Another of Not So Dark Heresy series, based on our recent campaign.
For those who don't know: In WH40K Dark Heresy, a Psyker must roll a dice anytime he uses his powers. When the Psyker rolls 9 on any of the dices used to manifest a power, he will invoke a Psychic Phenomena which often leads to the Perils of the Warp.
Since the Warp is very unstable and (haha) chaotic, the psyker gains Corruption Points. And it means lots of fun for all the team
