Atziri is becomming unkillable during her 2nd phase

This has happened to me both times i tried to kill her, fight goes down fine, but as soon as i get her to like 10% HP, she does her huge AoE nuke and then just chills spamming corrupted blood meteors and storm call.

This is the second time this happens since launch, and its really demoralizing spending ALL that time to get to her, just to lose EVERYTHING, because since I cant kill her, the only way to get out it to let myself get killed, and since that counts as you falling the temple, it gets completely destroyed, wiping hours of progression for absolutely nothing
