I finished the Maze Engine campaign on my rogue today, yay! Unfortunately I also learned that one of my rogue's daily powers, Lurker's Assault, doesn't play nice with the last fight at all. Part of its effect is that it teleports me towards my current target, but something about Baphomet causes this movement to get messed up.
Once I got stuck in the air and it was kind of funny because I could at least still hit the boss, but when it happened again I somehow got trapped on the outer age of the platform on which the fight takes place instead, unable to move back in or target the boss (though he could still hit me somehow). I tried to commit suicide by jumping down into the lava (and Drizzt dutifully followed me) but it actually ended up doing no damage to me and I just ended up stuck at the bottom of the room instead. The /stuck command didn't help either, and eventually I had to Alt+F4 to get back out.
Then I repeated the fight for the weekly quest, and the exact same thing happened again. I guess I just won't be able to use that particular daily power on this fight, ever.
