Just slew her on PotD. Well, that's just ridiculous in comparison with the original game. Even w/o starting WM2, it's way too easy on level 12. You run up to her all-party-in-line, cast hold beasts, relentless storm, get her stunned !!!!! and carve into mincemeat. Matter of 10 seconds max. Protection from fear, devotions and cleansing flame - that's the only casts by priest before she dies. Should try solo. Druid, it seems, is quite capable.
