Vaults of the Artificers

''House Cannith needs adventurers for its challenging enterprises - and will pay a king’s ransom! 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)''

Note challenges are partially free to play. By visiting the challenge token vendor in House Cannith, you will be given a number of challenge tokens free per day. Free to play players get 3 on their first character, and 1 on later characters on the same day. Premium and VIP get 5 on their first character, and 1 on later characters on the same day. 1 token allows one free entry into a specific challenge, or in the case of VIP or Premium players, you can use them to unlock certain bonuses from the vaults found within the challenges.

See Vaults of the Artificers/Daily Challenge Token Schedule to see what tokens are available on a given day, or here for a simple display of today's and tomorrow's tokens.

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. With 21 challenges available, this means there is a total of 126 favor possible. (*Note*: Stars are not earned progressively. Only the maximum number of "Star Objectives" completed within a single instance will be awarded.)
