He has extremely high defense and casts Holy, Flash, and Cure IV. He can be Silenced but resists it a lot. Elemental Seal and Silence at start is recommended. Bard's Threnodies will make it possible for RDM or WHM to land Silence, Slow and other spells on this NM. Paralyze and Blind will land without significant effort.
Periodically he will switch targets randomly, not based on hate. He will announce who his next victim is shortly before he switches targets. This causes a hate reset in the arena and generates a small amount of enmity to the new target.
Uses "Clobber", which appears to have a large AOE effect, possibly triggered by people behind him with hate.
At 50% HP, he will use "Granite Skin", a Stoneskin derivative. Standard attacks to his front will do no damage (Weapon Skills may do a slight amount of damage), while attacks from behind will still damage him. Dispel appears to have no effect, though it shouldn't take long to wear.
Below 30% HP, he will use a targeted AoE Fire-based TP move "Blazing Angon". Barfira and Curaga are recommended. A BLM and/or DRK should be able to stun it.
Around 25%, his Regen picks up and he tends to use Cures and Granite Skin much more frequently.
Elemental spells work pretty well. RDM's Thunder III does stable 500+ dmg on it. It's recommended to Chainspell nuke at last 20%.
Defeat the BCNM to start the next mission.
You are to escort Aphmau to Mamook on her mission to recover Ovjang. Will you find the automaton in the land of the savage Mamool Ja?
