Fight and lose to slime girl many time to increased their relationship..slime girl will be your cloth on high relationship ..you can fight succubus with slime girl as you armor,because it's impossible to beat her in normal terms
oh ok thanks
You can beat her without the slime-outfit, just need enough health potions and some luck.
If you have light magic before this it's pretty easy to wipe the floor with her.The issue is it seems you *have* to lose to progress, though I'm not sure if you get the dark magic book without beating her at least once.
