How do I transform into an Eternal?

Transforming into an Eternal requires you to obtain all 4 pieces of the Eternal’s Relic set. For example, you will need all 4 pieces of Irenna’s kit (Crown, Amulet, Weapon 1 and Weapon 2). 

Once you have picked up all the pieces, you can transform and unlock a new skill by holding the ‘X’ key on your keyboard or the L + R sticks on your controller.

Upon transforming, you will recover all fortitude and health, and have access to the Eternal’s unique skill, which can be activated by pressing ‘X’ on your keyboard or the L + R sticks on your controller, but you will be locked into using that build-out for the remainder of the match.
