During this promotion, keys are used to unlock gems rather than the traditional chests. The gems remaining to find are shown on the right side of the interface, so players can see what rarity of items they can possibly obtain. After unlocking 4 gems, players can choose to spend 100 Hearts of Ice to reset and obtain a fresh set of gems of varying rarities that may be unlocked, as long as there isn't a unique prize gem of ultra rare rarity available to unlock - it must be unlocked first. All players receive 10 Treasure Hunter keys as their first prize.
The original promotional prizes include shadow gem overrides, protean selections and a pack of 10 Treasure Hunter keys. On the promotion's return, all of the original prizes were available, while several new prizes were introduced.
