So I decided to make a trap disease that applies -0.8 to the player 'HealthRegen' actor value. I don't know if I can make this AV negative, but if not, I'll settle for making it 0. The idea is that once they have this disease, they will permanently and very slowly die (I'm nasty that way). If they're wearing an item of fortify health regen, I don't mind. I'll even leave a necklace somewhere to help (I'm kind that way).
They can also keep popping potions of fortify health regen. I don't mind that, either. I want the permanent cure to be one of a few potions thay can find in the dungeon.
Looking at the original disease system to see how to go about this, I just don't get it. The disease magic effects and enchantments have no special keywords, nor does the potion of cure disease, as far as I can see. I could find no formlist that is being used. There's just the effect archetypes 'disease' and 'cure disease'.
Unless I get how the system functions, I can't make progress with my new disease. Once I know this, applying it to the traps is no problem.
