D20 Design Diary: Why Do Inquisitors Get Teamwork Feats?
After I posted my draft of a Starfinder version of the PF1 inquisitor class, game designer and industry veteran Ryan Costello asked me a key question (and gave me permission to quote him on my blog about it):
“I noticed you mentioned in the conclusion that you are carrying over the PF1 Inquisitor teamwork feat focus. I always saw it as a strange fit for the theme. Any insight into why the class went that direction and why you are keeping it?”
So, this blog post is essentially my response.
I can only guess at the original design intent behind granting inquisitors bonus teamwork feats and solo tactics (which lets an inquisitor treat their teammates as having the same teamwork feats, making them much more useful) as a class feature in PF 1. While I worked on the book that was was introduced in, it was as a freelancer and all my work was to fill out support sections (archetypes, feats, spells, and so on), rather than do any design work on the base classes themselves. It’s worth noting that book was the APG, which is also where teamwork feats themselves were introduced, so it might be a simply and pragmatic decision to have one of the new classes tie into the new category of feats (as the cavalier class also did), and help differentiate them from clerics.
Of course one of the biggest fictional settings to heavily feature inquisitors is Warhammer 40k, and in that setting most inquisitors have a team of specialized agents that work for them. That doesn’t immediately equal teamwork, but the connection isn’t so tenuous I would discount it.
And you have to give inquisitors some kind of thematic hooks, and real-world examples of things like torture and bigotry don’t lend themselves well to the kind of heroic character Pathfinder mostly assumes players take the roles of. Also, with solo tactics, it’s less that an inquisitor is good at teamwork (working with people), and more that they are good at predicting how both allies and enemies will react in a way so precise they can use teamwork feats even when no one else is trained in those techniques, or even trying to use them. The inquisitor can work off people, taking advantage of their mere presence, almost like a kind of Super Combat Sense Motive.
Ultimately, I included the same thematic ideas because I set myself the task of creating a Starfinder version of the Pathfinder class, and I think this is a key element of that class, regardless of what the original thinking behind it was. But the fact it’s a different ecological niche remains true in Starfinder, which helps differentiate my inquisitor in a game system where there have been only 2 attack bonus progressions and 2 spell progressions to date, so something brand new always helps a class stand apart.
And, of course, since I designed my own teamwork feats, and plan to introduce them in the same book I introduce the final version of the Starfinder Inquisitor, the pragmatic consideration also applies. By putting a class with teamwork feats as a part of their legacy into a book that adds such feats (or, rather, my improved Starfinder versions of those feats) to the game, I am also driving greater engagement with different parts of the book.

d20 Design Diary: How Many Class Options is Enough (Starfinder Inquisitor example)
In the long run, this all comes back to the Starfinder Inquisitor I designed a draft version of. And, as a reminder, if you are a supporter of my Patreon in the timespan from today through tomorrow, you’ll get a slight-revised-and-expanded version of the class as a free pdf!
One common format of d20 game class design is to have selectable options as class features. These may be specializations — things you pick once that then give you fixed abilities as you gain levels (cleric domains, and sorcerer bloodlines are good fantasy examples of this, while mystic connections and operative specializations are the same idea in the Starfinder Roleplaying Game) — or may be a long set of talents that are abilities (some with prerequisites) you get to pick from every few levels (with the ur example being rogue talents, and everything from operative exploits, to mechanic tricks, and soldier gear boosts being iconic Starfinder examples).
These are things like will get endlessly expanded in expansions, campaign settings, houserules, and the blog posts of former-design-leads, so in the long run “enough” is “when the game stops being played.” But when the class is first introduced, you need to decide how many of these choices are presented to begin with. How much is “enough” to feel like there are a range of options with different focuses, themes, and effects. Obviously space constraints are always a downward pressure on these questions, but from a design point of view, you want there to be enough options at launch for players and GMs to have a feel for what kind of things you plan for those options to include, and for characters of the same class to feel different.
So, how much is enough? Well… it depends.
First, if you include bonus feats as choices (or the class feature is nothing but bonus feats, as with the fighter/soldier), you can count that as much more than one entry (depending on how many feats can be selected with the class feature). After that, it’s a question of how many different concepts you want to highlight, and how many such options a single character can take.
In this context, a character can only get a single specialization, so you don’t need as many of them. Talents, otoh, you usually get 5-to-10 of over the course of a single character’s career, so you need more to make sure that no member of the class is forced to pick the same talent as a different character with a different concept.
So, let’s look at the number of such class features that appeared in the Starfinder Core Rulebook, when the classes were first introduced. (I counted these by hand, so I might be off by 1 or 2 on one of these entries — which is fine, since I am looking for an idea of the range of options rather than an exacting tally.)
Envoy
Improvisations – 28
Expertise talents – 19
Mechanic
Artificial Intelligence – 2 (One being the drone, which has ANOTHER set of selectable options)
Mechanic tricks – 30
Mystic
Connections – 7
(The mystic also has spells, but that’s a bit different from selectable class features)
Operative
Specializations – 7
Exploits – 38
Solarion
Stellar Mode – 2
Stellar Revelation – 31
Soldier
Gear Boost – 12
Fighting style – 7
(These are in addition to gaining bonus combat feats at regular intervals, making the soldier highly customizable even with reduced number of gear boosts and fighting styles.)
Technomancer
magic hacks – 31
(The technomaner also has spells, but that’s a bit different from selectable class features)
It’s remarkable how similar some of those numbers are. It’s clear if you have an option that runs most of a class’s 20-level career, such as mystic connections, operative specializations, or soldier fighting styles, you want 7 of them to start. If you are doing talent-like choices, you want 20-40 of them (depending on how much the class depends on them, and how many other custom class features it gets).
So, what do we do with this knowledge?
Let’s apply it to our Starfinder Inquisitor., which is schedule to appear in a “full” version in the book Starfarer’s Companion II.

That class has inquisitions, which are very much in the “specialization” category for the kinds of class features we are discussing here. I only have one of those written up for the draft –the Battle Inquisition. I’m not going to have more than at-most one more for the free pdf version going to Patreon supporters, but when I release a “final” version of the class I’ll want 7 of those total. Offhand, I’d likely choose Battle, Madness, Occult, Solar, Technology, Tyrant, and Void for these first 7 slots, to give a wide range of options tied to both common Starfinder tropes, and inquisitor tropes from other science-fantasy fiction.
The class also has inquisitor tactics, which fill our “talent” design space. One of those — Team Tactics — is going to grant option to a range of teamwork feats designed for the class, so we can likely skew toward the lower end of the 20-40 talent number, especially since the class also picks either advanced melee weapon or longarm weapon proficiency at 1st, AND has spells. There are only 10 in the draft, so that number will need to be roughly double in the final version.

Genre Conventions as Game Rules
Years ago when I ran an RPG campaign called “the Masked Alliance,” (an alternate-history pulp masked-men campaign set in the 1930s on the cusp of the arrival of true powered superheroes), I borrowed from a lot of different game systems to create Detective! as a feat. (The core system was a no-Jedi Star Wars Saga kludge).
With Detective!, if you made an investigation check the worst result you could be stuck with was to figure out a location of another encounter that would give you more clues. No matter how badly you rolled, you got that at minimum.
So, if you rolled well, you might figure the whole thing out, and know where the main encounter was that would end that part of the plot. “This isn’t a typical stain. This is a splatter of Falernian wine, also known as “Cult Wine.” No one makes this anymore, except members of the Pantheon crime family. The pottery shards are new, made from clay available to the north of the city. A movie producer with suspected mob ties built a huge Greek temple out there he claimed was for an upcoming movie, but clearly it’s a Pantheon front. That’s where we’ll find the hostages.”
If you rolled badly, you at least figured out enough to get to another encounter (possibly just with thugs – masked pulp heroes do well with thugs).
“This is ‘Old Meadow” tobacco, which isn’t sold here. There’s only one importer in 200 miles that handles it, and they went out of business last month. They DO have a warehouse in receivership down on the docks… “
Only one player took that feat, for the Great Detective Vigilante character, but all the players loved it. The plot always moved forward, and no one complained if I had to come up with another colorful pulp-era encounter on the fly.
Last last bit it the rub, of course. Since I was kitbashing a game and I am comfortable with extemporaneous creation of new ttRPG scenes for my players, I was okay creating a system that depended on me being able to do that at the drop of a hat. But it does put a lot more work on the GM, and in a polished, professional release of the same idea I would feel the need to have a lot more guidance on how to do that (likely with tons of examples).
But it worked well in the game I used it, and it continues to be a thing I keep in the back of my mind.

d20 Spotlight Tokens
d20 Spotlight Tokens are an optional rule for most d20-rule based (or “T20”) games. The tokens are designed to give players a concrete way to grab some spotlight time (real-world time where they are getting the most done, being the most impressive, and having the most attention paid to them). These are absolutely a power-up in terms of what a group of PCs can handle, and that’s both intentional and, in my opinion, a good thing. It’s not an increase in what characters can do all the time, but it is a way for a player to decide to have remarkable success when the going gets tough… or when the player just wants that to be the way the story goes.
These are a mechanical solution to spotlight time. A player can’t help but be the focus of attention when one is spent, even if they are shy or not big talkers.
Once you have played with d20 Spotlight Tokens for a few game sessions, it should be obvious how to adjust for them as a GM. It may be the players simply choose to take on more encounters in a row, taking overnight rests or breaks to recharge abilities less often, in which case no adjustment may be needed. Or it may be appropriate to treat the characters as being one or two levels higher, so they face more dangerous opponents that require them to expend some tokens to succeed.

Spotlight Token Rules
You get one token per session, plus one per 5 full character levels. If no other player takes the same spotlight token as you, you gain 1 extra token per session.
Select one of the following tokens. This should be done, together, as a group. If two players choose the same token, they can decide if they want to overlap, or one or both of them change their choice. Once this choice is settled, it cannot be changed until you gain a level or another player selects the same Spotlight Token you already have (in which case, again, you discuss it and one, both, or neither of you can change your choice).
You can spend a Spotlight Token immediately any time the relevant game event occurs, even if the action has already been resolved. For example, if you select the Attack Token, you can spend it after an attack misses, or after it hits but does less damage than you want. When you spend a spotlight token, you also get one additional full round of actions you get to take immediately. This additional round of actions does not benefit from the powers of the Spotlight Token–for example if using the Assault token attacks you make as part of your bonus round of action do not also automatically hit.
Currently, here are the token choices. They are designed to lean into common character focuses, and to have more than one options for each broad focus.
ARMOR – You take no damage until the end of your next turn.
ATTACK – Your attack (anything requiring an attack roll) hits and does 150% its max damage.
ASSAULT — Your attack (anything requiring an attack roll), and all attacks you make before the beginning of your next round, hit.
CRITICAL — Your attack, effect, or spell (anything requiring an attack roll) is a critical hit, if it has rules for being so (for example of a spell does not require an attack roll and has no rules for being a critical hit, it does not benefit from this token).
DEFENSE – An attack misses you, as do all other attacks from the same source until the beginning of your next turn.
EFFECT – One foe fails a saving throw against a spell or effect of yours. If there are degrees of failing a saving throw (such as an additional penalty if the save is failed by 5 or more), it takes the worst effect.
MANA — You activate one spell or ability you can use at least once per day without it counting against your normal uses per day.
OVERCOME — You get to take a single action that can be performed in one round or less, that you would be able to take if your character was not suffering any damage, penalties or effects, and without applying any penalties for current damage, penalties, or effects. Yes, even if you are dead.
RESIST — You succeed at a saving throw, and at all other saving throws from the exact same effect (such as all saves against a poison, or against one ongoing spell).
SKILL — You may choose for one skill check (regardless of how much time it represents), or all skill checks you make in a single round, to be treated as if you had rolled a 20 and the d20 roll.

d20 Design Diary (Part 6)
This is the sixth in my series of class-focused d20 Design Diaries. I suspect I only have a couple more posts to go on this topic, but we’ll see how the topics actually shake out (and what kind of feedback I get).
If you followed class design steps in the order I have written about them, we’ve settled on an appropriate and interesting class concept, set up the right class progression tools, made sure we are following (or at least only breaking by intent rather than by accident) the game’s style and etiquette, looked at how many options you want for each level of your class and how that impacts complexity, and discussed spell access and progression.
But we still need to talk about spell lists. Specifically, do you give your new class access to one (or more) existing spell lists, or make a brand-new spell list? And, it turns out, that.s a pretty complex question that depends very much on the game system you are using.
So, you know, let’s start by saying studying what that system does and how it handles those questions.
Also, it’s very important to know if you are building expansions classes that are in addition to a *core* set of pre-existing classes or are building a whole set of classes from scratch. Most of the advice here is directed at the former case. If you are in the latter situation, there may not even be pre-existing spell lists for you to borrow from. In that case you’ll need to make decisions about how many class lists to build from scratch, and the following advice may still be applicable to that decision.
Certainly the more you want a spell list to have a very strong theme tied to the class’s concept, the more you should consider a unique class spell list. The more you want the spell list to interact and grow well with other publisher’s content, the more you should consider using an existing class list.
In Pathfinder 1st edition, classes have access to a hodgepodge of class-specific lists, sharing class lists, and mixing class lists. The bard has its own spell list for example (though the skald later gains access to it as well), while the warpriest just has access to the cleric list (though it gets most spell levels later in its own level progression, when they are less powerful compared to the challenges being faced). Both sorcerers and wizards use the sorcerer/wizard spell list, though it has specific spells only one of the classes can take. Hunters get both druid and ranger spells (and gain access to ranger spells much earlier than rangers do, potentially making them more powerful compared to the challenges faced when you first access them), but inquisitors have a unique spell list.
Counting only official classes, no alternate classes, and only actual spell lists (as opposed to formula lists for alchemists and investigators), by the end of its run Pathfinder 1st d had 16 separate spell classes. On top of that, all of the class spell lists are defined as being arcane, divine, or occult.
In that environment, it seems insane to create a brand new unique class list. First, there are tons of lists with different themes already. Second, each of those lists has been expanded by so many supplements (official and otherwise) that any new lists is either going to fill a small book on its own, or have many fewer options than the 16 existing lists. Further, if someone is adding content from other publishers, those 3pp spells won’t even know to suggest what new spells should be on your unique class spell list.
By the same token, by the time a game has 16 unique spell lists, it’s hard to claim a 17th will be the bridge too far for design weight.
Pathfinder 2nd edition, as a counterexample, has only 4 spell lists. Absolutely every class has access to the arcane, divine, occult, or primal spell list. Some classes can pick what spell list they access based on other class features (such as the sorcerer), and many classes have access to a very small number of “focus spells” unique to their class. This includes both classes with access to a traditional spell list (such as the bards and their occult spells), and classes with no other spell access (such as champions). While it would be possible to build a whole 5th spell list (akashic magic, perhaps, or runic magic), this would likely only make sense if designing multiple classes that accessed it, or perhaps writing class variants of existing classes that accessed your new magic type. However, adding a small number of focus spells to any new spellcasting class, but otherwise tying them to one or more of the 4 existing lists, seems an excellent way to both benefit from that class having unique and flavorful spells of its own (new focus spells) and benefiting from ties to a growing standard spell list that other books and companies can expand. Pathfinfer 2nd ed also has things such as spell rarity which could be used to create “new” spell list options (such as creating a magister class that has access to common spells for multiple lists, but can never gain uncommon or rare spells).
By contrast Starfinder goes the opposite route, and give every spellcaster their own unique spell list.
Starfinder only has 3 official spellcasting classes so far of course, and each also has the same level of spell access and spells/day. That certainly sets an expectation for players that a class focused on spellcasting would likely follow the same path. There are many potential reasons to not go that route (if creating a mechanic/technomancer hybrid class, the Dronemancer, that only had access up to 3rd level spells, it might well make sense for it to have the technomancer spell list), but again the key point is to know what tools are at your disposal, and study how the core game (or similar games, if you are starting from scratch) use them.
Dungeons & Dragons 5th ed also gives each class its own spell list (at least in the Player’s handbook), including the sorcerer and wizard, who shared a spell list when the sorcerer was first introduced in 3rd edition. There is greater variety in both spell access (paladins and rangers only get up to 5th level spells), and how the class uses spells (warlocks and wizards have very different game mechanics dictation how they interact with and use their spells). The larger number of lists makes it more likely that you can match a specific class’s theme with an existing class list or combination of lists, but it also drives home player expectation in much the same way Starfinder does.
As a final note, it’s worth mentioning that whether a game has dozens of class spell lists or just three, d20 games almost always have some basic spells that appear on multiple (or even all) spell lists. the most flavorless and utilitarian spells are often there, from detect magic to light. By the same token, most such games have at least a few types of spells that are kept off specific spell lists, in the tradition of “clerics don’t cast magic missile, wizards don’t heal.”
But honestly, that’s another whole blog post worth of commentary.

Design Diary: Creating d20 Classes (Part 3)
Last month we began a line of Design Diary entries discussing how to create a character class from scratch for a d20 class/level based game. We’ve gone over concept, and discussed the class progression tools various games give you to fill out the mechanical roles your class might fill. Now, it’s time to begin discussing the heart of what makes a class fun and unique–special abilities.
Of course there are lots of elements to good special abilities. Balanced numerical considerations. Well-worded rules. But also, matching (or intentionally breaking from) the game system’s class organization etiquette.
Yep. Etiquette.
Each d20-based game system has an etiquette on how classes are presented, which you need to understand on order to build a set of class features players will find satisfying and relatable. Yes, you can challenge it, but you need to know why it’s there and understand how GMs and players may react to a class that doesn’t follow the system’s rules of class presentation etiquette.
Since we haven’t talked much about special abilities yet, let me use a progression bonus example to explain what i mean/
If you were making a Chaos Adept class for Starfinder, you could perfectly well decide it has a +2 base Will bonus at 1st level, +0 at 2nd level, +3 at 3rd and 4th, +1 at 5th, and +4 at 6th. Done properly, that can be balanced, and match the class’s theme. None of those numbers are out of whack for balance purposes at the levels they are presented, so the class is not in that regard unbalanced.
But it breaks etiquette in a big way. A lot of GMs will flip out. It LOOKS wrong, since every other class in Starfinder uses one of just two progressions, which all march slowly upward at a regular pace. It also makes it really hard to a player to know if the class is one that in general is “good” at Will saves. If they want to be more mentally resilient than ususal should they invest in Iron Will or similar save-boosting options? Most players won;t have a clue.
Further, the class if going to give different end result feels at different levels. Sometimes it’ll feel very mentally resilient, while on other occasions it will seem weak for entire levels of gameplay at a time. That can be chaotic, of course, but it puts a lot of mystery into how the class is going to act, forcing the player to guess or do a fair amount of analysis before discovering what to expect from the class.
Is that worth the chaos-themed-feel? You can’t answer that questions until and unless you understand why the etiquette existed to begin with.
Different games handle how the class gains bonuses to basic tasks and game functions differently. Proficiency values are fixed in 5e, it’s what you apply them to that varies. Proficiency tiers are given as specific levels in PF2 and have set values. No one ever gets a d11 hit die in any of these games, even though d11s are easily available.
Using a specific set of tools and presentation makes it much clearer to players and GMs what a class is good at and should be able to do. Breaking those norms has consequences, and you need to grasp what those are before you can decide if your off-the-wall design is worth it.
There’s also some Picasso at work here.
If your choices appear entirely random and disconnected from how the game you are designing for builds a class, players and GMs have little reason to trust you know what you are doing as a designer. Suspicion and confusion can very quickly lead to gamers spending more time picking about the game design than playing the game, and that is unlikely to lead them to feel they got good value out of what your spend so much time and hard work creating.
On the other hand, if your class design is familiar in how most of it is presented, the places you do deviate from the norm are more likely to be accepted as mindful, intentional efforts to make something new and innovative. Like a work of Picasso, at least some people are going to evaluate something that breaks the normal conventions in the context of knowing the creator has proven to have mastered the normal rules of that art form first. Picasso mastered the conventional styles of art in his field, and was then able to change the rules from a place of understanding what they were and how to use them.
So, analyze how the existing classes in the game present everything from bonuses to proficiencies to class features. In Starfinder, every class has beginning armor and weapon proficiencies, class skilsl and skill points/level (and in general twice as many class skills as the number of skill points it gets per level), Weapon Specialization at exactly third level, and most have a few set core abilities every few levels and one or two different sets of tiered ability choices with level prerequisites.
By contract, 5e classes all have a proficiency bonus that increases by level (at exactly the same rate for every class), fixed abilities at most levels (generally with one kind of choice at 1st or 2nd), and one or two points where the player picks a specialization. Classes don’t have special class abilities that are picked every few levels in 5e, though things like feats and spell selection still have an element of that.
So if you want to introduce a whole new mechanic of player (say, a system of runes that don’t work like any existing class feature as I have in the runecaster class now available through the 52-in-52 program), you want for everything else in the class presentation to follow the normal class etiquette. Not only does that show you knew what you were doing, it lets gamers who look at your design focus on learning the new rules you are presenting, without having to also grasp a totally different presentation of information.
You CAN change anything you want as a designer. Just make sure you only do so when the result is worth the cognitive load on your customers.
Next week, for sure, we’ll talk about fixed abilities versus customizable abilities. 🙂

Design Diary: Creating d20 Classes (Part 2)
Last week we began a line of Design Diary entries discussing how to create a character class from scratch for a d20 class/level based game. We tackled a number of questions about the concept for you class then, and now it’s time to look at taking that concept and turning it into playable game mechanics.
And that starts with the tools d20 games give you to define the base competencies of your class, and how quickly they progress.
Class Progression Tools
The heart of a good character class is its special abilities, but you don’t have to start with those. In fact, beyond a general idea of what you want its special abilities to be able to do, as part of settling on a class concept, I prefer not to focus on special abilities until I have more of the class’s framework in place. That framework is made up of various progressions — health, skill points, class skills, beginning proficiency, base attack bonus, base saving throws, and spell progression.
In most d20 games, there are only a few progressions available for these, and they are often interconnected in non-obvious ways. For example, in 1st edition Pathfinder, a class that gets a “full” base attack bonus progression (+1 to bab per level gained) always has at least a d10 Hit Points per level (the sole non d10 full-bab class is the Barbarian, who gets the slightly-larger d12), and no one gets a d10 or higher Hit Die unless they have a full bab progression.
In general, you want to have a balance of good, moderate, and bad progressions. In some cases those progressions already come in those quality levels–in most d20 games your base attack bonus progression can be good (+1/class level, like the barbarian, cavalier, fighter, soldier, and so on, also known as a “full” bab progression), moderate (+2/3 levels, like the bard, cleric, envoy, mechanic, and so on), or poor (+1/2 class levels, such as the sorcerer, witch, and wizard–interestingly Starfinder has no classes with this progression). In these systems it’s easy to see that if you give a class a good attack progression the focus of that class is combat, if you give moderate bab progression it is going to have numerous combat options but will either need abilities to make it more effective, or must accept that combat is a secondary function, and if you give it a poor progression it’s never going to be good at combat without special abilities.
There are some built in potential problems with those progressions that show up over 20 levels of play (the gap between a fighter’s chance to hit and a wizards goes from as little as 5% at 1st level to 50% or more at 20th), which several newer d20 games have tried to solve by having very different ways of rating who is combat. pathfinder 2nd edition has a flat progression of everything from level (+1 to attacks per level for all classes), and uses five ranks of proficiency (untrained, trained, expert, master, and legendary, or U/T/E/M/L) and class features to differentiate which classes are combat-focused. Most classes are at-best trained in various weapon categories, while the fighter begins play expert in some attack options. Similarly 5e has a flat “proficiency bonus) (ranging from +2 to +6) which classes can add to various attacks, defenses, skills, and ability score checks, and class features (the barbarian’s rage, the fighter’s fighting style) determine who is good at the raw math of combat.
The best way to begin a character class is to see how many good, moderate, and poor progressions (or whatever similar mechanics the game in question uses) a typical class gets and which classes have which progressions. Normally a class that is strong in combat has weaker skill options but more HP, and characters with strong spell abilities have weaker saving throws. These aren’t hard-and-fast rules, but you want to make sure every class both has strengths and weaknesses, and that it’s bonuses and game mechanics support what the description and flavor tell players the class is good at.
That last element can be tricky, of course. If you have a Combatant class (not a great name, but fine for example purposes) which you describe as the best class at combat, and a Big Boxer class which you describe as the best at unarmed combat, it’s going to be frustrating for Big Boxer players of the Combatant is better even at unarmed combat than Big Boxers are. On the other hand, you don’t want all the flavor and mechanics of a class to just be a difference on where they get their bonuses. You could have an Archer class and a Smasher class and have their only different be the Archer gets big bonuses to ranged weapons and the Smasher gets them to hammer attacks, but that gets boring and tightly locks those classes into narrow character concepts.
Spellcasting deserves a special note here, because not every class gets it, and it has a huge impact on character effectiveness. The most obvious variable in levels of spellcasting is what level spell a character gains access to–in early d20 games it’s often a question of 4-level spellcasting (such as the paladin and ranger), 6-level (such as the bard and all official Starfinder spellcasting classes), and 9-level (such as clerics, druids, and wizards). But even within that there are important distinctions such as how effective a spell list is at specific things (the wizard spell list has more and better offensive options than the cleric, for example).
Again, not every d20 game keeps this set of progressions (5e has 5-level and 9-level casting, PF2 has 10-level casting and access to specific focus spells), but each game generally has a few standards you can borrow when building the superstructure of your character class. If you don’t feel like you know what the progressions and proficiencies of the core classes of the game you are designing for are, you need to do some study and analysis before you try to write a character class for that game.
You don’t have to get all this right in your first pass–if a class initially feels like it’s going to be strong at skills and spellcasting and weak on everything else, and then analysis or playtesting reveals that limits its options too much, you can go back and beef up some other progression to give it more core competency. But handling your initial idea of progressions, proficiencies, skills, and spells up front also helps define where things like special abilities should go. If a class doesn’t gain any spellcasting (or mutations, psionics, superpowers, miracles, or whatever) in a game where such powers exist, it’s worth thinking about how that class is going to deal with things that DO have supernatural powers when writing the class’s special abilities.
Because special abilities are the heart and soul of most classes. And we’ll look at them, especially fixed abilities versus customizable abilities, next week!
