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.
29-42 Life Science
57-70 Physical Science
85-90 Sleight of Hand
98 Profession (Pick one at random)
99 Sense Motive
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.
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
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.
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.
