Benedictus boss fight break.

In the Benedictus boss fight in Act 4, if you damage and kill him faster than he can phase change, he will start the death animation and the electrical field attack at the same time. There are no visual queues for the electrical field attack since he is in his death animation and if your character dies during that time, the scene breaks and Benedictus will start talking before teleporting off screen with the precursor forge doors staying closed.

Same, triggered the last sequence when benedictus gets killed by Tavakai but died to an exlposion of his that still went off. Respawning results in him vanishing and being unable to proceed without reseting the zone.
him teleporting away is quite funny though.
