The grand Adjudicator phase 2 won't trigger.

Somehow, “Aurelian, the Grand Adjudicator” won’t trigger Phase 2 and stays immune to damage for a very long time.

I just died in T16 HC because he was immune to all damage and ailments (since Phase 2 needs to start for him to take damage again). He kept spamming all his moves for at least a minute and a half. I got caught and died to one of his very large AoE spam attacks (he even used some Phase 2 moves).

The most annoying part is that after he killed me, Phase 2 triggered immediately, which really got on my nerves.

This boss already has so many bugs, but this one is the worst I’ve seen so far.

Please review this, GGG.

My bug is thah this boss has leave the arena. And i'm in...

How can i do to echap ?
