Hang on, Binder Fred...
I don't think it was a fireball -- more like damage from a flask of burning oil. Or, to be more precise, a Glyph of Warding is what I think it was -- a first level spell 3rd level, sorry. And, like I said before, Klyman was given several chances to avoid or lessen the damage and even save vs, death and be left with 1hp if he did take full damage. That's nowhere in the rules AFAIK, it's just a gift of the DM that my suck-a$$ rolls spoiled. And, truth be told, I almost decided to let the flask lie and ignore it.
I like the job Imperialus has been doing, and I like the job you and everybody else has been doing. So please, please, don't let this hiccup unravel the whole game!
I must say, though, Imperialus, I have had second thoughts about making the new Dwarf a PC - forgot he only had one hand now. A one-handed thief doesn't sound to good....
