Wait, it flees? It should never ever flee wtf!
I'm adding that to the bug report. You're supposed to seduce the alter ego.
I try but once [redacted] is fully lustfull , any attempt past that is ignored, if u try to fuck, it will say that u don't know how to fuck it. I tried to seduce it and had max lust and 15 more attempts to flirt but nothing happened other than it killing me.
When i try to kill [redacted], it will flee at 20% health
However I found that attacking the lonely bunny form with a fay will remove the ego and cure it.
