Various venomous snakes have this “may become septic if victim survives” verbiage regarding their bite wounds. That looked fine to my editorial eyes, but now I need to rule on it as a referee, because (lo and behold) a PC was bitten thrice by vipers and survived. The game effects of septic wounds aren’t detailed. I’m thinking of applying a slower version of the inflict disease spell but am open to suggestions from the forum.
