General Information for all Phases

  • Never move out of melee range from the boss. If you are hit by an Arrow you cannot collect Greens. You should always stand on the edge of the boss’ hitbox.
  • When you get Spreads, dodge them inwards or sideways at the last second. You can stack spreads with other players, and dodge all of them at once.
  • When you see Greens, intercept them by standing on them. Make sure you do not move from the boss to do this: only intercept them when they are in melee range, while remaining on the edge of the boss’s hitbox.
