[Powers/Thaumatology] How to Model This?

[ajardoor]

Okay, I have a concept for a villain's gimmick; he gets bonuses against people who have deliberately harmed him or failed to help him after he did a favour for them. So he starts every encounter with a hero by helping them out with some problem, and let them take the first shot, to get the bonus. If the villain takes the first shot deliberately, he doesn't get the bonus. These bonuses apply to spellcasting rolls (any system of magic) and the mundane rolls that benefit from High Purpose (think Slay Demons or Slay Undead from Dungeon Fantasy).

Can someone think up stats for this kind of thing? Advantage? Perk? Just a special modifier system? Thoughts?

I would simply go with levels of Talent for this, with an Accessibility limitation. "Only applies against people who deliberately harm him or whom he has helped and hasn't reciprocated" seems like -50% to me. So just buy the level of Talent you need to get the bonus you want, apply that limitation to it, and you're good. For these purposes, I'd treat limited Talent as separate from unlimited, and allow you to buy levels that exceeded the normal +4 cap.

Sounds suspiciously like Higher Purpose.

Yes, sounds like HP to me too.

What is the point cost of the traits?
