Is there a secret to beating her?
I get her to like 60% health on stage 1 and then get slammed by mechanics.
I watched some videos and there are some where they get her vulnerable and she melts.
I never get her vuln.

ISO some help.

It’s possible but extremely difficult with the low damage builds

Lilith is just a terrible fight. Unless you’re using a broken build don’t bother

Especially since the spark is glitched and the vast majority of people don’t get it anyway

Practice avoiding the attacks that give you tormented stacks.
