Chest O'Plenty (NM)

Chest O'Plenty and Coffer O'Plenty have the same behavior.

Spawns as the faiulre condition for the A.M.A.N. Trove battlefield. Instantly uses Ka-thwack, killing everyone without reraise in range and drawing-in anybody not in range.

Immune to Stun and Silence. Susceptible to Lullaby.

Appears to have four distinct phases, transitioning at 100%, 69%, 39% and 9% health.^[1]

Phase 1 is a fight against a fairly standard NM. It casts its full complement of spells and uses its physical damage TP skills and Death Trap.

In phase 2, it will alternate between two magic-absorption 'modes.' One mode absorbs all Light-skillchain damage (fire, thunder, wind included) and the other mode absorbs all Dark-skillchain damage (ice, water, earth included). The mode changes appear to be triggered by consecutive weaponskills, which may be retaliated against with a use of Death Trap.

In phase 3, it retains its magic-absorption mechanics and will take now greatly reduced damage of all types and gains the use of Pandora's Curse/Gift.

In phase 4, the fight reverts to Phase 1 damage mechanics but Ka-thwack is greatly increased in potency.^[2]

Proc red removes

Strong enough damage of the 'correct' type of elemental damage will proc blue and removes the aura gained by Ka-thwack in phases 1-3.
