Yearner

Notes:

 * Spams Carousel, which consumes 2-3 shadows.
 * Because of this, NIN tanking is ill-advised for this fight.
 * Spiritreaver Automatons, avatars, and /SAM DDs are recommended.
 * Uses Brain Spike for a heavy amount of damage.
 * Did around 400 DMG to a PLD with over 600DEF and PDT-5%
 * Seems to increase in attack speed as its health gets lower.
