GammaFinder Mutantiary part 1 (Hammerderm)
So we introduced some quick and easy rules for GammaFinder, a post-apocalypse campaign hack for Starfinder, introduced the concept of the Unburned World and its relics (Halidom), and then gave some Halidom game rules. We’ve done one pretty standard theme for the setting, and two really weird ones.
Since GammaFinder is remaining popular so far, I thought it was time for a Mutantiary (like a Bestiary, but for weird mutant threats). Of course, these can be used for any Starfinder-compatible setting.
We start, with the hammerderm.
HAMMERDERM CR 7 [COMBATANT]
XP 2,400 each
N Large Magical Beast

Offensive Abilities ping
STATISTICS
Str +5; Dex +4; Con +0; Int -4; Wis +2; Cha +0
Skills Athletics +14, Intimidate +14
Languages none
SPECIAL ABILITIES
Bounce Off (Ex) When an adjacent character makes an attack against a hammerderm and misses, but misses by less than 5, the attack literally bounces off the creature’s hide and reflects back at the attacker. The hammerderm makes an attack roll with a +13 bonus and, if the attack hits, it does its base damage (not including Specialization, ability modifiers, or special abilities) to the attacker.
Ping (Ex) The vibratory sonar of a hammerderm can be focused into a massive damaging “ping”. This counts as a ranged sonic attack with a 30 feet range increment and the deafen critical hit effect. It can fire through a material the hammerderm is currently burrowing or swimming through, but not other materials in contact with it — a hammerderm can ping through the earth it is digging through, but not through a concrete slap or boulder sitting on the earth. A target hit by the ping must make a DC 15 fortitude save or be deafened for 1d4 hours.
Hammerderms are much feared alpha predators most common in areas with long stretches of uninterrupted soil or sand, such as planes, prairies, deserts, river deltas, and beaches. They appear to be some horrific blend of shark and rhino, though its unclear if they are actually a product of mixing the dna of these creatures of if the Unburned World process that created them simply followed the from of those natural animals.
Hammerderms have massively powerful passive sonar, able to sense virbations in soil, water, and even the air making them almost impossible to sneak up on. They also possess an offensive sonic “ping,” a deafening bolt of focused sonic energy projected from an organ known as the tintabulum that runs along the front ridge of their head. If a hammerderm is killed without using any bludgeoning or sonic damage, the tintabulum can be extracted and sold (making up treasure equivalent to the appropriate amount for the hammerderm’s CR).
Hammerderms travel alone or in mated pairs, except when the moon is visible in the evening sky before nighttime, when they gather in small herds of 7-12. Hammerderms give live birth to 2-4 “peens,” which emerge fully capable of fending for themselves. A typical hammerderm is 12-15 feet long and weights around 5,000 lbs.
This is Just The Beginning
If the Mutantiary proves popular, we can do so much more with it! If you are looking for more GammaFinder-appropriate mutant critters right now, you can check out the grizzly boar and rattle-cat, which were designed for Really Wild West, but also work great in GammaFinder!
Want More GammaFinder?!
I now depend on my Patreon for more of my income and support than I ever expected to. If you find any value in my blog posts or videos, I could use help with the Patreon. If you can spare a few bucks a month, it’s a huge help. If not, even just sharing and linking to my blogs, videos, and the Patreon itself is a huge help that just takes a moment of your time.
Thanks, everyone.
Halidoms: Relics of the Unburned World for GammaFinder (Part 2)
Okay, we’re still discussing Halidoms, for GammaFinder! We introduced the concept in yesterday’s article, and now we start looking at game rules.
Halidom Game Rules
Halidoms are a form of item that come without instructions. The GM can replace 25% of all treasure given out with Halidoms, though they are most common as Moderate and Major items.
The good news for layers is that if you find a Halidom, getting it to work gets you a scaling item. A halidom upgrades itself as you gain levels (normally once every 5 levels, based on when a version of roughly the same item is available with a higher item level). The base news is, you may blow yourself up trying to figure out how to use it.
Halidom Key Skills
Every Halidom has a key skill that is the primary way it was designed to be interfaced with. In 70% of cases this is Computers, Engineering, Life Science, Mysticism, or Physical Science. In 20% of cases, it’s Culture, Diplomacy, Medicine, or Sleight of Hand. And in 10% of cases, it can be literally any other skill. That said, take it easy on Halidoms with Profession as their key skill–there are a lot of different Profession options, and no group can possibly cover them all. On the other hand, a quantum knife that keys of Profession (cook) is both reasonable and, if we are being honest with ourselves, funny. (I like the idea of “Soup’s On!” as a battle cry…)
A GM may pick the skill to match either the form of function of the Halidom, if desired. For example, a laser pistol that takes the form of a small remote control steering wheel (which is used to guide a targeting dot like a flying remote, with a gear shift to fire the weapon) might have Engineering (for the laser weapon aspect), Physical Science (for the general laws dictating how such a device works ), or Piloting (for the actual interaction with the device’s steering mechanism).
On the other hand, it might interact with Culture (to recognize the Unburned World toy name brand and marketing), Acrobatics (because you have to twist and turn the device to make its various functions work), or Bluff (because it constantly asks if you have parental approval to use it without the safety systems engaged).
A GM can also just roll on the table below to determine a Halidom’s Key Skill.
Roll 1d100
01-14 Computers
15-28 Engineering
29-42 Life Science
43-56 Mysticism
57-70 Physical Science
71-75 Culture
76-80 Diplomacy
81-85 Medicine
85-90 Sleight of Hand
91 Acrobatics
92 Athletics
93 Bluff
94 Disguise
95 Intimidate
96 Perception
97 Piloting
98 Profession (Pick one at random)
99 Sense Motive
100 Survival
Discovery Checks
A Halidom does not come with instructions, and it doesn’t work in a way that is obvious to adventurers of the GammaFinder World. Even if it looks like a gun, acts like a gun, and has a trigger, a Halidom gun may require you to think a mantra in praise to the Saint of Bullets before you pull the trigger, or might have a palmlock that requires you to fake only having 3 fingers, or might only work when held sideways.
And, of course, it might exactly like the serum of healing that requires you to place the gunlike object against your own thigh and pull the trigger.
There were reasons for all these odd things to exist, and they made sense to the society of the Unburned World. But those reasons were based on philosophies and conditions that are in many cases inconceivable to heroes of the world as it exists now, and the factors that caused such unusual designs are long-lost to the Chasm of History.
When a character first encounters a Halidom, they can make skill checks to try to determine its Key Skill. The base DC for any such check is 15 + 1.5x the Halidom’s item level. Any skill that is NOT a Halidom’s key skill has a -5 penalty to all checks regarding the Halidom.
Until a Key Skill is identified, all characters can do it pick a skill, and use it to interact with the Halidom. This can be done once an hour, unless a side effect deactivates the Halidom for a time. You cannot intentionally activate a Halidom until you make enough Identification results to gain that knowledge.
Halidom Interaction Skill Checks
Beat DC by 10. Make a Identification roll.
Beat DC by 5. Identify that if skill being is Key Skill. DC lowered by 1.
Meet DC. Identify if skill being used is Key Skill.
Fail DC by 4 or less. Minor side-effect.
Fail DC by 5 to 9. Minor side-effect. All DCs increase by 1 until Key Skill is identified.
Fail DC by 10 or More: Major side-effect.
Identification Rolls
Roll 1d4. If you get a result you already know, you get the first result of a higher value you haven’t gotten yet.
1. Learn Item Level
2. Learn Item Function (Small Arm, Upgrade, Computer, and so on)
3. Learn Key Skill’s ability score
4. Learn Key Skill. +1 to all future rolls (cumulative with getting this result multiple times)
5. Learn a hapahazard activation. (Can activate Halidom, but suffer a minor effect when doing so unless you succeed at a Fortitude or Reflex save, DC 10 + Halidom’s item level). +1 to all future rolls (cumulative with getting this result multiple times)
6. Halidom mastered, can be used normally.
Minor Side Effects
Roll 1d6.
1. Item changes Key Skill. Any activation is haphazard (as 5, above) until Key Skill is identified.
2. Take damage of a random physical type, 1 point per item level.
3. Take damage of a random energy type, 2 points per item level.
4. Weird discharge. You are sickened for 1 hour per item level.
5. Weird discharge. You are confused for 1 round per 2 item levels.
6. Discharge. You are targeted by the item for its normal function (if it cannot affect targets, nothing happens).
Major Side Effects
Major side effects function as a wonder grenade, but the area is a radius with a number of feet equal to the Halidom’s item level, rounded down to the nearest 5 feet. If that is less than 5, it only effect’s the triggering character.

Halidoms: Relics of the Unburned World for GammaFinder (Part 1)
I introduced GammaFinder, a post-apocalypse campaign hack for Starfinder, yesterday. The response was… positive. 🙂
So, now I am exploring what kinds of rules we can add to that simple framework to help bring the PA flavor to a GammaFinder campaign. We begin with halidoms… which are going to need to be split into two articles. Here’s Part One.
The Unburned World
No one is sure what happened to create the GammaFinder World. Some say it was a war, fought with quantum reassignment projectors, x-ray-pumped lasers, and boson bombs. Others think there was a Great Disalignment, when magic flooded into the world, dragons awoke, demons rose, and common citizens turned into trolls, orcs, kasatha, and wizards. Other theories include a genetic virus, the Gray Death, luddite cults, social anarchy, and even a rogue comet. The records of the time of the Burning are muddled, contradictory, and confused, as if a half-dozen worlds got shoved together into a single shared disaster.
The Chasm of History
History, in short, has a Chasm. On this side, the GammaFinder World. Before it, the Unburned World. And in the middle… anarchy, pain, horror, and disagreement. What is certain is that before the rise and fall of the great cities of Alpha and Beta, there was a very different place, able to do things no one can conceive of now.
Halidoms
There are… things… left over from the Unburned World. Or at least, from the time of the Chasm, if not the world before. Objects. Strange devices that use super-science, eldritch powers, or some combination of the two to create effects no one in the GammaFinder World can duplicate. They are often the thing that allows a town to survive in a harsh terrain, grant a petty warlord his power of metal men, or make cursed places seen as vaults of wonder and horror.
These are sometimes called relics, fragments, antiquaries, or crytobjects. But for whatever reason, the most common term for these Unburned Icons is “halidoms.”
Appearance
A halidom can look like… anything. Some are straightforward–a sword hilt which can project a sunblade. A vial of liquid you drink. A talking teddy bear which informs you of the ill intent of nearby creatures. Others are obtuse. A cube made of 27 smaller cubes which slide and shift into different configurations. A gnarled knot of roots and vines that are never observed to move, but constantly seem to be in different shapes. A tiny metal sphere with incorporeal lights orbiting it.
The problem is, form does not seem to follow function. A sword hilt may project a sunblade… or it maybe designed to be shoved into a rock that forms a mouth that gives medical advice. A vial of glowing liquid may be meant to be drunk, or it may hold the soul of a cryptowizard that casts one random technomancer spell a day. A spoon may full a bowl with soup, or it may project a sunblade.
A GM wanting a jumping-off point for the appearance of a halidom can roll 1d10 and consult the table below. It’s important to note that players don’t get to know what you rolled–if a haildom looks like a gun, that could be because its a kind of gun and you rolled a 1, or it could be a computer, and you rolled a 5.
- Typical appearance for its function (a gun looks like a gun)
- Representational appearance for its function (a gun looks like stone with a gun-shaped rune on it)
- Appears to be a puzzle with no link to its function
- Appears to be a toy
- Appears to be a typical appearance for an unrelated function (a gun that looks like a vial of serum)
- Appears to be a shifting mass of some specific material (a gun that looks like a ball of wires with tiny lights traveling along them)
- Representational appearance unrelated to its function (a gun that looks like a holy symbol)
- Appearance of a household object unrelated to its appearance (a gun that looks like spoon).
- Appearance of an item of apparel with some hint of its function (a gun that looks like a glove with a barrel on the wrist)
- Appearance of an item of apparel with no hint of its function (a gun that looks like a belt)
Most denizens of the GammaFinder World don’t risk trying to determine the function of a halidom once they realize what it is. But PCs are made of sterner (or dumber) stuff. So they tend to… experiment.
We’ll get into the rules for interacting with a halidom tomorrow.

GammaFinder — Simple PA rules for Starfinder
I am a huge fan of Post-Apocalypse games. That may be why I wrote for Sword and Sorcery’s Gamma World line, and d20 Apocalypse.
Setting
The world ended. A few times. But for living memory, there were two Great Cities — Alpha, a land of ancient technology and highly-educated people living in a gentle, safe, totalitarian Bubble; and Beta — A huge, sprawling rough-and-tumble metroplex of rivers and bridges and canyons where mutants and rogues lived and traded and taught and sometime killed each other, but were free of most outside influences. Both had occasional visitors from a Third Great City — Gamma — but no one knew where ti was or what it was really like.
The Omega Invasion was unlike anything that had been seen in centuries. New horrors, new machines, new creatures, wiped out Alpha and Beta. The OI seemed poised to wipe out all life… until the Gamma Strike, which wrecked their bases and leaders, and left them in a scattered wreck of damaged robots and crazed ex-soldiers and experiments.
But there are Omega Invasion forces left, and they are trying to rebuild their armies. So heroes must seek out Gamma, and see if it can be convinced to once again save the world of the GammaFinders.
Level
Characters start at 4th level. The GammaFinder World is a harsh place, so we start with more competent characters. And that means you are just one level of a nice ability score bump!
Starships
Not happening, don’t worry about them.
Emphasis
Every character gets an emphasis. There are three available at the moment.
Mutations: Select one item of your character level -1, or two of your level -3. You gain the abilities of those items as mutations. If they use batteries or ammo, you can use the ability as often each day as one full load of ammo or batteries. As you gain levels, you can change these items. When you gain levels you can improve your mutations to higher-levels of the same thing, or switch to entirely different items your mutations emulate, to represent ongoing mutation.
Relic: Select one item of your character level +1 or less. You have an ancient piece of tech that does what that item does, though you can change its appearance. If it has batteries or ammo, you refill them each time you spend Resolve to regain SP following a 10-minute rest. If your relic is lost or destroyed, you get a replacement when you gain your next level. You can change your relic at each character level, to represent the shifting effects of this ancient technology.
Talent: You get one bonus feat at every odd level. You must meet the prerequisites. Alternatively, at each off level you can gain one additional spell slot of the highest-level spell you can cast at that level. If you select this latter choice, you are likely described as a “psionic” or “witch.”
Items
You get one item of your level (Major Item), one of your level-1 (Moderate Item), one of your level -2 (Minor Item), and one of your level -3 (Incidental Item). If it’s a consumable item, you can replace it when used at the beginning of each day (you may be able to make a new one, or find a new one, or have something that produces refills for it once per day).
These items don’t go up in level automatically, and if lost are not replaced.
Level Advancement and Treasure
You gain a level every 12 encounters. Over 6 encounters, you expect (on average) to get one Major, one Moderate, one Minor, and three Incidental items. If you have the ranks in a skill needed to make an item, you can convert an items of the same type into a different item, once. Every time after that you convert and item, it loses one item level.
That’s it! It’s otherwise just Starfinder as a quick-and-easy PA setting!

Social Distance Thoughts. GM-less 5e Gaming: Part One – Skills
Pandemic changes things. For everyone’s sake, we need to adapt. For our own sakes, we need to stay sane.
At least for the next few weeks, a lot of us aren’t going out and doing the things we normally do. That leaves us with only online options to interact with friends.
RPGs are a great way to spend time with friends. And if you are willing to go theater-of-the-mind, it works great just via chat or video conference.
But, no one may be in the mood to act as GM.
So, a group of 2-4 friends sure CAN run through a pre-generated adventure without a GM, or a map. Just treat it as a board game, deal with one encounter at a time, roll targets of attacks randomly, and don’t get too hung up on things like tactics or worrying about player knowledge. One Facilitator reads each encounter as you run into it (and maybe that role rotates), and players agree to deal with things cooperatively.
You can even use these ideas to run yourself through adventures on your own, a kind of Gaming Solitaire.
But… it might be nice to have some guidelines for things like skill checks interacting with encounters, when you don’t have a GM to make rulings. So:
GM-less 5e Skill Rules
This is just the beginning of a potential ruleset for playing through a published 5e module with friends, likely online and without a virtual tabletop, and without a GM. This is a first set of thoughts—the beginning of this idea, rather than the end.
Group Skill Decisions
When you want to try something the text doesn’t give you guidance on, the group needs to decide on a DC for the effort. The player proposing the action suggests an ability and related skill, and describes how the action would work. The group then sees if they can agree that the thing being proposed would be Very Easy to accomplish, Easy, Medium, Hard, Very Hard, or Nearly Impossible. The default DC of anything the group can’t decide on is 20 (Hard).
Ability Checks Table: Typical Difficulty Classes
Task Difficulty (DC)
Very Easy (5)
Easy (10)
Medium (15)
Hard (20)
Very Hard (25)
Nearly Impossible (30)
Each ability score lists the skills associated with it, along with typical results for success and failure of skill checks that aren’t specifically outlines in the adventure. Have fun with these checks. Describe the attempts, discuss how the story plays out. It’s a different kind of roleplaying, but no less fun or effective for being more cooperative.
For example, the adventure says there is a locked door. Kyla suggests her barbarian should be able to shoulder the door open with a Strength (Athletics) check. The group agrees that’s possible, but given it’s a sturdy, well-maintained door, it’ll be Hard. Kyla attempts a DC 20 Strength (Athletics) check. If she succeeded, she could bypass the obstacle (forcing the door open). As it happens she fails. The typical failure for Strength Athletics) is to take Damage equal to DC -20 -2d6. That’s a base of 10 (DC 20 -10) hp of damage. Kyla rolls 2d6, and gets a 7, which she also subtracts. She ends up taking 3 (10 -7) points of damage, and the door is not open.
Strength
(Athletics) – Success: Overcome one obstacle. Cause one monster to be unable to act for 1d4 rounds. Failure: Take damage equal to task DC -10 -2d6 (minimum 0).
Dexterity
(Acrobatics) – Success: Overcome one obstacle. Cause one monster to be unable to affect you for 1d3 rounds. Failure: Take damage equal to task DC -10 -3d6 (minimum 0).
(Sleight of Hand) – Success: Take one item of fist-size or less from the encounter. Cause one monster to be unable to use an item for 1 round. Failure: Disadvantage on defensive rolls for 1 round.
(Stealth) – Success: Escape an encounter. Examine an encounter without triggering it. Failure: Trigger an encounter, lose turn failing to escape the encounter.
Constitution
Endure a hazard or circumstance for 1d4 rounds without taking additional damage or penalties.
Intelligence
(Arcana) – Learn the details of one magic creature, effect, trap, curse, or similar item. Failure: False information causes you to be at disadvantage for your next check against the magic examined.
(History) – Learn the details of one ruin or established settlement, or item pertaining to it. Failure: False information causes you to be at disadvantage for your next check against the place or related item examined.
(Investigation) – Learn the details of one location you can examine unhindered. Failure: False information causes you to be at disadvantage for your next check against the location or a related item examined.
(Nature) – Learn the details of one natural creature, effect, hazard, location, terrain, or similar item. Failure: False information causes you to be at disadvantage for your next check against the natural creature or phenomenon examined.
(Religion) – Learn the details of one religion or a related creature, effect, trap, curse, or similar item. This specifically includes angels, demons, devils, and undead. Failure: False information causes you to be at disadvantage for your next check against the religious subject examined.
Wisdom
(Animal Handling) – Success: Overcome one animal-based encounter that has not yet become a combat without it becoming one. Cause one animal to be unable to affect you for 1d3 rounds. Instruct a friendly animal to take a specific action. Failure: Bad interaction causes you to be at disadvantage with your next check with the relevant animal.
(Insight) – Success: Learn the true intentions of one intelligence creature. If the creature intends to attack you, you may take an action to begin the combat before the creature does. Failure: Bad conclusion causes you to be at disadvantage with your next check with the relevant creature.
(Medicine) – Success: Learn the nature of one disease or poison. Stabilize a dying creature. Prevent a disease, bleed, or poison from affecting its victim for 1 round. Failure: target takes 1 hp.
(Perception) – Success: Learn all elements of an encounter. Failure: No penalty.
(Survival) – Success: Live off the land without using up supplies for 1 day. Avoid one natural hazard. Locate a natural encounter and observe it without setting it off. Failure: One random party member takes 1 hp.
Charisma
(Deception) – Success: Overcome one non-combat encounter with intelligent creatures. Gain advantage on your next check with one creature in a combat encounter. Failure: You are at disadvantage on your next check with the creature you attempted to deceive.
(Intimidation) – Success: Overcome one non-combat encounter with intelligent creatures. Gain advantage on your next check with one creature in a combat encounter. Failure: Creature attacks you.
(Performance) – Success: Gain advantage for the next check a party member makes in a non-combat encounter with intelligent creatures. Failure: Suffer disadvantage for the next check a party member makes in a non-combat encounter with intelligent creatures.
(Persuasion) – Success: Overcome one non-combat encounter with nonhostile intelligent creatures. Failure: No penalty.
