I don't watch in window with fight communicates. But i think U're right. My first oppinion about this (after fight) was "son-of-a-bitch infected me", and "it will be part of mod content, I find something later".
But nope.
I have save near to this fight and i loaded, replay fight and... after each hit of this furry bastard my character under line with suffer damage has line with "saving throw vs breath weapons". It's not vs death (like U wrote), but i think this is responsible for change app/ lycanthropy curse after fail s-throw. In this second/test fight Master Werewolf hit mi 30-40 times before i decided to finish this, but there was no change, maybe all saving throws were positive? Dunno.
I think we have source of this mess, ok, but in that case it must be in GLOBALS, yes? Like "PLAYERLOOKSLIKEDROW = 1" after Adalon spell in Underdark.
Idon't know: "WEREWOLFCURSE"? "LYCANTROPHY"?, or something like that...
But which line? I don't see anything in GLOBALS, dunno.
Damn.
Someone known?
