Friend A2 notably with Excalibur and Discernment
So Zargabaath is pretty godly in this fight since he can buff everyone with confusion resistance and drain all of Skeletor's MP in one round with Judgment Blade. The problem is he can't do both of these on the same round. And in later rounds you need to be draining MP every turn. There is a disturbing lack of Confusion resistance gear in this game.
WoL uses Arms Breaker, Light is With Us, defend every 3 turns.
Fina uses Ritual+2 and that's it.
Orlandeau uses Pod abilities and Divine Ruination.
A2 attack every round with Dash Attack, Finisher, or limit break.
So i had Skeletor down to 14%, but he killed WoL. I decided to gamble on killing him off instead of recovering WoL. Nope, only got him down to 2%. He wipes everyone but Zargabaath. Zarga spends a couple of turns trading attacks, but Judgment Blade is just offsetting Skele's healing and I'm spinning my wheels. I gamble for a second time on Zargabaath's limit break. It kills, barely. *sweatdrop*
Got no white magic and 5-man missions, didn't care about getting the summon mission.
