From fiery crystal mines and kobold-infested islands to fantastic extra-planar vaults, Cannith needs you for missions of acquisition and conquest. Contains 12 challenges and Epic Level Loot! (Level: 4-25)''

Introduced in Update 12, this adventure pack offers 4 new dungeons. These 4 dungeons are separated into 12 challenges with different rewards available. 9 of these challenges have a separate "Epic" variation available, for a total of 21 separate variations across 4 dungeons.

Completing challenges grants favor for House Cannith: 1 Favor point per star achieved, plus an additional favor point if you 5 star a challenge on its maximum available level.
