Untouchables aren't very good at resisting Psychic Powers right now.
"But they get massive bonuses!" I hear you cry.
"No, they don't," is my response.
Now, let me explain. I'm cool with there being multiple levels of Untouchable. That's fine, with varying talents and things. Totally cool.
However, their best thing - resisting Psychic powers, frankly, sucks.
Psychic Null revolves around using Deny the Witch, or opposed WP checks.
The thing is, they only get one Reaction a round. This is pretty bad. If they get shot at, and dodge, or parry an attack, they can't Deny the Witch. If they're against two psykers, they're toast. This even applies to the Culexus Assassin, providing you shoot at it enough to wipe out the extra Reactions.
My solution is simple, and prevents us going back to 1st ed. Untouchables:
Deny the Witch doesn't require a Reaction. It does not require skills such as Dodge, as he isn't Dodging to Evade.
This means it can be used multiple times per turn. Characters who invest a ton of XP into it could become immune to certain powers, but that's okay. They'll still technically be able to get beat in opposed checks, but it'll be tough, which is fine. It's very likely their 'special thing'.
