Slime Queen/Lust Grimm

Slime Queen (クイーンスライム Kuīn suraimu) is the seventh boss in Lust Grimm, found in the Waterway. She returns in Lust Memory as the fourth boss encountered.

Profile
''A pink slime. She has high intelligence among the slime succubi. She captures men inside her jiggling body and sucks out their strength along with their semen. She is having a hard time trying to dispel the image of slimes as weak and insignificant.''

Skills
Royal Drain: drains level and does damage, used more often if Lust greater than 70%

Join The Family: high damage, leads into Become As One

Become As One: follows Join The Family, 5 hits

Heal*: restores 5000 Vigor

*: not actually named in game

Strategy
Like the normal Slime, Slime Queen has absurd defence but low HP. Equip the book "The Blue Light" and use the skill it grants, Lust Dream. This always does 100 damage and so will defeat her instantly. It is possible to defeat her using your most powerful moves, but these will generally take more than one hit, giving her more time to level drain you.
