I'm going to begin pay in a campaign and am playing a Psion Telepath, who'll become a Mindthrall. So I'm an evil face -type who enjoys controlling people. I've never played a Psion in Pathfinder before and I'd like to know which of Mental Intrusion and Impose Will would be more useful to me?
I'll be the only Psion in my group and quite possibly in the campaign world (I'm from another dimension), so some powers wont be useful to me at all and I won't be going up against other psychics.
