I hate that SP draining skills I think from incubus. not sure.
What card should I use to stop this. The only thing I am lacking from Razer's list is the Kalitz. Ty
Cant be stopped. Carry GJ. Magnificat helps too.
Or Gunslinger. 
Have you played long enough with a gun slinger down there ? Spirit destruction, high defence of enemies, Less HP mod of a slinger are the obstacles I think of.
Hundreds of Grape Juice, Hundreds of Slim White Potions (now mastella fruit because its buyable). Between it and Skellington, I got to 99. Got Soul Staffs, never a succubus card, sup with that.. ;/ I promise you, as long as I say I've played, I know how the game is able to be played. Double Santa Porings on a Garrison, Desperado GG.
Edit: Yes, that does mean I was down there before reaching level 99.
