Treasure rooms spawn randomly during a compaign run. The room is easily distinguished by the formation of your heroes lining up along the back wall of the room as three chests fall down in front of them. The type of rewards gained from the chests are tiered based on rarity. The rewards do not increase as you level up and will thus receive the same reward as a new player or as a veteran player.
Upon choosing a chest, a status will show the type of rarity chosen and the rewards gained.
- Good - This reward gives a small amount of gold and hammers.
- Great - This reward gives a moderate amount of gold, hammers, and a random Evo larvae.
- Amazing - This reward gives a moderate amount of gold, hammers, a random Evo and a random Hero Token (but not above the Hero Rarity gold). When a treasure room is found then there is a 25% chance to get an Amazing chest.
Dungeon levels affected by increased hero token and gold drops in daily events will also double the number of Hero Tokens and gold gained.
A maximum of one treasure room can be spawned in a dungeon level.
