Just fought Andariel in Torment 1 Hardcore. At the beginning of the fight she took damage as normal. But a short time into the fight, she stopped taking damage. Yes the totems were destroyed and she should have been open to attack, but her health appeared to be infinite. Possibly related to the stat squish?
The character died.
I just wanted to report the bug.
Its not a bug but a normal behavior of Andariel mechanics.
I have beaten Andarial many times in previous seasons. The mechanics are simple she is damagable then throws up 3 totems in boubles. Destroy the totems then she becomes damagable again. Rinse repeat.
But this time after her shields go up. And the totems are destroyed. Her health becomes near infinite.
