have qualified that . . I never fight that beast unless my party is at least level 65 and my Gladiator has GM Spear (with two Artifact Spears - I try for 2 Gungnirs). My Assassins will have at least a 20 (hopefully 25) Blade Skill and are using at least 1 Artifact Daggor and 1 Basilard (hopefully of Stoning) apiece.
My Priest, by that time, has 15 Skill Points in Dark Magic (skill at the Expert level) and GM 10 in Light and Spirit. 10 points in Elemental at Master level. She os also Master Bow and Cudgel by then.
During this combat, my Priest's main function is to cast DI when needed, but in between she casts Poison Cloud.
My Priest very rarely casts offensive magic and I have her in the party primarily for travel and healing. With the Assassins at GM20+ in Blade, they are getting 10-15 attacks per turn and the Gladiator at GM Spear gets 6 attacks per turn.
One last note, when fighting him in melee, keep your finger on the "Up Arrow" key and his Wing Buffet will be minimized.
