Echo of Lilith result in unkillable boss

Hey, so I’ve already beaten the game and I decided to tackle the Echo of Lilith, and Ive come across a HUGE glitch. In 1st phase, every now and then, Lilith will drop to like 1/32nd of her health, and NEVER lose the rest of it, no matter how much i hit her. If I happen to make it to the 2nd phase, the 2nd phase will NEVER drop below 1/32,and just kill me. I survived over 60seconds on the 2nd phase trying to win, but it just would NOT lose health. This has amounted in an unkillable boss glitch, and needs to be patched ASAP.

That is how Lilith rolls. Try Rob2628 build then you will defeat her.

On the 2nd phase, are u getting to the end where she cuts all 3 tp parts of the stage? Once you get to that point she will take damage and be killable. Shes designed to do all 3 stage cuts before she dies. Good luck
