I was trying to finish up that blasted signature questline and am on ST Forgotten Catacombs. I read the thread where Frost seemed to be bugged in the heroic instance, but I can't seem to kill Frost in the solo version either. When he casts Pile Driver, I threw a globe at him,, beat on the pillar like the scipt says to do (I am a fury and my merc is the assassin). What happens is first I can't send my merc in to attack the pillar,, it keeps attacking Frost,, once the globe is thrown and pillar deactivated,, I throw every big nuke I have at the pillar, and nothing seems to happen. Either I am doing something terribly wrong, or this mob/instance is bugged.
