  • When the defiance bar breaks, players get access to the Keep Construct's core.
  • Swipe - Keep Construct swipes at the players.
  • Backhand - Keep Construct slams his right arm behind him.
  • Construct Aura - A passive aura which damages all players in the arena.

Special Mechanics
  • Colored Orbs - At both 66% and 33% health, Keep Construct will become invulnerable. At the same moment white and red orbs will begin moving from the statues to the Keep construct. Players may stand in the way of the orb of the same color they are attuned to, and absorb the incoming orb. The more orbs reaching Keep Construct, the more damage he will cause at the end of this phase.
  • Construct Core - Keep Construct withdraws from the battle temporarily exposing three spirits protecting its core. If the three spirits are overcome, the Construct's Core becomes exposed and can be pushed (or pulled) through unstable rifts. Pulling the core through rifts will increase the damage Keep Construct takes upon his return.
  • Insidious Phantasms - When two (white) phantasms merge, they will form an Insidious Phantasm.
  • Radiant and Crimson Phantasms - When radiant and crimson (white and red) phantasms spawn on the battlefield, each player will receive a random attunement. Players may only kill phantasms of the same attunement as themselves.
  • Xera's Fury - Large circles will spawn under each player and a red circle will slowly expand outward. Once the circle is fully filled, all players within the circle will be dealt a moderate amount of damage.
