Ketzuli, High Priest of the Sun crash

Ketzuli's eye beam attack ("Gaze of the Vaal!") sometimes crashes the game. The crash seems to become more frequent over time, as it did not crash at all during my first two attempts, but from the fourth attempt onward this ability crashed the game about 50% of the time. This crash did not close the instance, and upon logging back in the fight continued from where it left off.

I'm having the same issue. Logging back into the fight instantly crashes the client again. I can log into town and repeat the fight, but if that move is used I crash.

Same. I've tried creating new instances, updating my gpu drivers, clearing the shader cache, etc. It seems to be happening with the gaze attack. I cannot get through the fight.

I've had the same thing happen twice now.
