The Gauntlet consists of 15 waves. After each wave is complete, a reward of a random item (shards and Heroes included) is added to a large number of gold and/or Dragoncoins. The Gauntlet can be reset once per day and unlocks at Level 30.
After every successful wave completed, you are offered a brown chest. Brown chests contain gold and random items; the amount of gold and rarity of the items increase the further you go in the gauntlet. After every 3rd victory, you will receive a red chest. Red chests contain Dragoncoins, gold, and better items. It is not uncommon to receive Blue or Purple items, shards, or even tier 1,2, or 3 Heroes from Red Chests.
There are a total of 12 items sold here:
- 5x Prometheus and 5x Hecate shards at 500 Dragoncoins
- 5x Helen shards somtimes spawn in place of Hecate shards at the price of 800 Dragoncoins
- 2 EXP consumables like Wisdom Potions, Wisdom Salves, and Wisdom Cakes
