Where to unlock?
  • You can unlock new cards by finding them inside chests. Some of the rarer chests have a better chance of unlocking new units. Other cards can be unlocked by participating in Events or Brawls or by purchasing them in the Shop.
  • Artifacts can only be unlocked in the Lab by spending Doh Shards, found in the Tower of Loot.

  • Cards can be leveled up to make them stronger. To level up a unit you must collect enough cards of a particular unit and collect enough coins for the Upgrade cost. Once both requirements are fulfilled, you can level up the card to make it more powerful!
  • Artifacts cannot be upgraded.
