Hi
I am a relatively new GM to Dark Heresy, we have only been playing it for about 3 months. Last session something terrible happened. the Psyker in our group experienced his first psyhic phenomena, rolling 99 he had to roll Perils of the Warp as well, coming up with a 93. Daemonhost. this led to a wild discussion, since apperantly there was no roll the psyker could do to prevent this, not even to use his mercy blade to kill himself.
After much flipping and reading through the rulebooks and checking the interenet. We decided to go for an optional rule, a opposed Willpower roll to see if the psyker could maintain enought controll to use his merceyblade. but of course he didn`t stand a chance.
I noticed that the effects on Perils of the Warp somewhat superseedes the other rules about deamon possession found in the rulebook.
My question is: can the psyker burn a Fate point to avoid this happening to him? I found nothing to support that when reading over the Fate point rules. They appear rather vague, and the whole section about fate points is rather short.
Is there anything that could help my player`s character? I will hate to let him die simply because of a freakish dice roll, but I am a GM that follows the rules, and are bound by our group`s codex: never to cheat, never to break rules.
