This is related to the Slayer (but I didn't want to start a new topic for such a small thing) but in the slayer change dialogue then there is the following option:
+ ~False()~ + ~I accept, despite the risks.~ DO ~IncrementGlobal("SlayerDeath","GLOBAL",1)
SetGlobal("Slayer10","GLOBAL",2)
SetGlobalTimer("TheSlayerTimer","GLOBAL",60)
ApplySpell(Player1,SLAYER_CHANGE_TWO)
ApplySpell(Player2,DRAIN_PARTY)
ApplySpell(Player3,DRAIN_PARTY)
ApplySpell(Player4,DRAIN_PARTY)
ApplySpell(Player5,DRAIN_PARTY)
ApplySpell(Player6,DRAIN_PARTY)
ForceSpell(Player1,SLAYER_FEAR)~ EXIT
Any ideas?
Btw, I this dialogue option is viewable in InfExp in my no-mods install of BG2 but not my modded version. I don't know what removes it although my guess would be either Ascension (which adds new options to that dialogue) or you've already dealt with it in UB.
