Phantasy Star IV (Genesis) - Boss 05
Gens v2.12 Movie 11
Chaz - level 18
Gryz - level 19
Ryka - level 18
Demi - level 15
Rune - level 21
Easier boss than the previous one, he has only single target attacks. Just be sure to use Saner to play quicker than him and Deban and Barrier to set defenses.
I tried using Blizzard by combining Chaz' Zan and Rune's Giwat, it was not very convincing. Maybe it would have been useful with Gizan instead of Zan, but Gizan requires five more levels for Chaz to learn it.
