The eleven Immortal Compendium rewards have been released.
Compendium owners will find Immortal Strongboxes in their Armory. Strongboxes work just like our new Treasures, granting no duplicate items for the nine primary Immortals. Each Treasure also has a chance of granting up to two bonus Immortals.
Each Compendium comes with one Immortal Strongbox and about every ten levels you are awarded an extra Treasure. You can level up your Compendium by performing tasks and by purchasing extra points.
