Omega Planetes
Omega Planetes becomes much more dangerous when it activates Pantokrator mode. Keep hitting the head so it focuses on one hunter who can steer those attacks. If that hunter is in trouble, another hunter can take the focus by hitting the head again. Hitting the legs opens more attack chances. When it charges Delta Attack, it summons a Nerscylla clone. Kill that clone before the charge finishes so a shield appears, then stand in the shield when the beam fires. If the clone lives, there is no shield and the beam ends the quest. Fire works on the clone; Thunder works on Omega Planetes.
