Lilith, is inherently OP. But I'm cool with that because of catching her off guard and I assume she's the plot villain.

To counter act with how strong she is, I've made her more of an assassin like character. While she can be quite invulnerable, you can still do tactics that can stun her and stuff like that. In addition, she can still be overwelmbed with attacks (But not be killed by mortal hand and weapons), not to mentioned surprised and wounded with enough force, and when she feels like enough is enough or that she's losing, she will often retreat or leave your character with a mind fuck. So she CAN be "defeated", just not be killed with the mortal hand. She'll more often retreat then kill, as they are not worth her time. She has her mind on vengence with TWO people/angels (took at the bio for that info).

Yes she will be a plot character in the future and yes you'll probably still encounter her before that time comes. BUT, I got an anti-character covered for her, Adam, who'll I'll make some time more in the future. 

Don't worry though, she may sound OP, but I'll use her right and fairly. :)
