Mutators

• Mutators are modifiers to enemies that spawn in the Onslaught game mode. You will be able to see with what lanes get x modifier(s) before starting. These can be an advantage or disadvantage to the enemies or can grant additional effects.
• Double Mutators start at floor 22.
• As of the Shifting Sands Update Pain Aura has been removed due to poor performance. To compensate, Bloodlust, Trollblood, Speed Demons, Berserked, and Reckless has been added to the game.
