Yeah it's this topic again. Recently one of my players started a psyker/noble character. He chose the basic healing power from minor powers ("knit flesh" I belive it was called) and a firestorm power from the pyromancy range. Know I knew that psykers could be lethal in DH, but he's character is simply riddiculous. During the first enagagement he burned 6 xeno creatures to ash with a single firestorm, and altough he went down soon after (the rest of the party abandoned him), this still proved decisfull for the whole combat.
During the last engagement he burned, with two firestorms, 5 cultists. He rolled a 9 only 3 times so far, and each time spend a fate point to prevent the manifestation. So much for the "use you powers on your own ris" thing.
But that's not the worse thing. He's basically a mobile healing station, even tough he plays a noble that everyone insult and dis. During a travel trough the warp he spend two whole days healing a single character. This really takes the tension of my game, and what's worse, he told me at the creation of his pc, that he'll be very selective with who he's healing. Bullcrap. You simply ask him, and then he heals you.
On the other hand, during the last session one of the npc's that's running with my team, insulted him and the psyker cast "fearfull aura", debilitating half the group, and, I'm pretty sure, breaking the sanctioning rules. However I know, that the rest of the team, even tough they ar emad at him, will still use him a medipack with powers, especially the arbites, who is kissing his ass like there's no tommoorow, even tough he's pious and hates witches. He was the witness of the "fearfull aura" thingie, and the only thing he did was to pull out his pistol and wave it in fornt of the psykers face. A friggin Adeptus Arbites! But then again I understand he's shitty motives - live psyker = free healing. Damn it….
So here's my qyestion - what should I do with this situation? Should I kill of the psyker. There are enough witnesess to what he has done? I don't really wnat to change the power ruling, but then again thi scharacter is basically imprevious to the manifestations/perils of the warp, beacuse he has still 3 fate points, and even when he casts his powers with 3 dices, he still rarely rolls any 9's.
My players already think that the difficulty level is too high in my games, but with this goddamn boltmagnet I can't see any other way to continue with our games, without starting to throw more heavily armoured/dangerous oponnents at them, altough I'm afraid that it will really disturb the balance of our sessions.
So - firestorm, epic healing and bad meta gaming - how can I deal with them all? Any ideas would be greatly appreciated.
