I'm currently fighting the gluttony demon but I can't seem to defeat him, can anyone give me some tips on how to beat him?
I found the heal on climax, MP leech on enemy climax, increased enemy climax speed skills work great on it. Just smack it with a charm when your HP or mana is looking like you could use a pick-me-up, and then let the tentacles do their thing. You get a free hit (or several), a free heal, and free MP.
