After playing this game for a while, I discovered a problem.
There's no spell that seems to ensnare or arouse the monster girl further to want to have sex with you.
Well, that's not the real problem, the problem is when you upgrade a spell to become able one shot the monstergirls, you can no longer interact with them since the requirement to unlock sex animations with them is to get them low on health, and I don't know what other requirement since there's no help book that seems to mention it.
So, it would be nice to have a spell that allow us to not kill monstergirls, or allow us to downgrade our spells that one shot them. Or just allow us to unlock regardless of essence when clearing an entire dungeon, that's the simplest fix.
Well, the other fix I can think of is allowing us to upgrade the artifacts, like that cloak we get to immediately allow us to have sex with monstergirls whose max health is just 25.
Like
level 1: Once the monstergirls current health are <= 25 in health, allow sexual intercourse
level 2: 30 *
level 3: 35 *
And so on.
