I believe that the achievement “Who’s Afraid of the Dark?” in the Vault of the Wardens dungeon is bugged.
I’ve done it multiple times and have not been given the achievement. I start the fight by picking up the light. I throw it at her in the middle of the room then DPS her down to 40% where she casts Creeping Doom. I dodged all the walls and then attacked her once she came back down. I had to pick the light up to reveal the avatar mob she spawns that shields her. I have killed her while holding the light and also while the light was on the ground.
I was told by a GM that I’m basically S.O.L and it’s out of their hands. They also suggested that I use in-game bug reporting in addition to submitting a forum post to ‘increase visibility’. One or the other should suffice but I don’t want to allow the next GM to say something to the extent of “Should have made a forum post”
I have no idea what’s going wrong with this achievement. I am absolutely confident that I dodged all the Creeping Doom walls and my combat logs reflect that statement.
Any help is appreciated.
