I've got a new player and so, for the first time, a PC Astropath. Most of the Psychic stuff makes sense to me, but there's one little thing I can't find anywhere in the book; What dice to you roll to check against the Psychic Phenomena Table?
When I first read it, I assumed it was a d100. If this is true though, how does the Astropath's "Roll an extra d10 and drop one" abilitiy work?
