Starting a separate thread since the update thread seems to be overwhelmingly about new items.
Main boss: Bozzetto Conjurer with Garuda pet. Has aura when avatar is out and is super evasive til avatar is killed. Fairly innocuous except for his Kamaitachi move (similart to Yagudo AoE sweep kick) and can one-shot non-tanks (did 2500 dmg to me).
Appears with BRD, BLM, SAM, MNK, NIN. The adds can do there respective SP moves and have bonus evasion (?) when they have buffs.
On our attempts, all mobs including the NM were easily slept with Troub/Night Lullaby. However, the boss seems extremely magic resistant even when its avatar is dead. My RMA (in full AF acc gear including regal earring) bard had trouble dispeling and sleeping the boss and avatar.
