Mutators are special conditions added to maps in Co-op Missions rotated on a weekly basis every Monday. They reward players with bonus experience depending on the difficulty. They were introduced in Patch 3.3.0.
This mutation applies to "Oblivion Express."
- Inspiration: Enemy Heroic units increase the attack speed and armor of all enemies within a small range.
- Aggressive Deployment: Additional enemy units are periodically deployed onto the battlefield.
- Avenger: Enemy units gain increased attack speed, armor, and life when nearby enemy units die.
Mutators are special conditions that bring additional challenge and diversity to existing Co-op Missions. Mutators can vary wildly, from having to fight a completely cloaked army, to dodging lava erupting from the ground. Mutators vary on a weekly basis. Each week, players have the chance to take on a Weekly Mutation where several Mutators are applied to a Co-op Mission. The mutation will be available for seven days with a break before the next one begins. Difficulty levels can still be selected, as can normal Co-op Missions, with the ability to toggle between the two modes.
If players complete the weekly mutation, they will be awarded a tiered XP "bounty" bonus based on the difficulty level selected. Completing a weekly mutation on a higher difficulty level will award the cumulative sum of all XP bonuses up to that level. For example, completing the weekly mutation on Hard will award the sum XP bonus of Casual + Normal + Hard.
