Lilith's Way Of Fighting!
-----
Lilith was already amazingly talented at magic the moment she evolved thanks to Chaos' Miasma, her magic and mana stats were through the roof, and in Hell, they taught her a lot of Illusion Magic, a magic that dealt with illusions, charming, hypnosis, and more.
It also had a branch, dream magic, which could help Succubus find new mates through visiting men that had wet dreams.
But she couldn't do it for anything sexual!
Chaos allowed to go to the library where there were many magic books, and she ended spending several nights without sleeping there.
At some point, after a few days, a new Lilith showed up.
"I won't be a burden, and I will help out my master…!"
And since then she had been joining Chaos expeditions, slowly becoming a common member, and forging a strong friendship with the other monsters in the party.
