Nasty little Krish. I have only done one TPK in my time as a DM and that wasn't my fault. The group had a dwarf that had taken two sorcerer levels so he could go and use detect magic on everyone, just in case they carried magic items he could use. So, they meet some archwizard thats 12 levels above the highest leveled player and the stupid, dum, no longer in the group, dwarf attacks. I didn't even bother being nice, the mage just killed him outright, as he deserved for his actions. After all, If I was a 23 rd. level Wizard, I wouldn't think twice about fragging some little dwarf that attacked me for no reason, especially if I was neutral-evil. The rest of the group foolishly tried to assist, instead of merely letting the dwarf die (which is good team spirit though).
