Belberith is a Legion-Look A like...In a way.

Agh, I stuck once more, lolz, funny I thought bezoubel was hard. Belberith is kinda the same thing just uglier and more powerful...So, anyone got more tips for me, maybe i'll try level my party first.

Fly and Phantasma demon skills are invaluable in that fight. Just teleport up to him and smack him in the jaw.

Mazandyne, wind amp and wind boost. Belberith is weak to force. Or are you having problems with the shomonkai grunts ?_?

[Ike.]

Do the following:

Pair your MC (or highest-powered magic-using character, preferably Yuzu because she's fast) with a demon that knows Phantasma and another that knows Awakening (Deity class).

Equip the following on said character:
Active
Zandyne (and/or Force Dance)
Drain

Passive
Wind Boost
Wind Amp
Dual Shadow

Auto
Blitzkrieg

Teleport over to Belberith. Cast Awakening (Magic dmg x1.5). Attack.

Cast Zandyne/Force Dance. If you're lucky, Dual Shadow will make it fire twice. Repeat until dead.
