Fought this guy yesterday in a Lv.8 Mamool Ja Besieged. Uses the standard list of Mamool Ja Blue Mage spells, but seemed to use them with a more strategic AI than most BLU mobs. Also uses Vorpal Blade, Firespit, and the Besieged-only TP move Groundburst.
He will cast Yawn (AoE Sleep), and quickly follow it with a Groundburst. This is done quite often, and due to the high damage of Groundburst, wiped many people.
He might be able to use Self-Destruct. Damage is very much like a Mijin Gakure from NIN mobs, and as such does not KO Panurgic Ryubool Ja.
