Elemental Dungeons is a part of the City with four dungeons, each linked to an element: Earth, Water, Fire, and Air.
You can only use heroes of the same element as the dungeon you choose to fight in.
Every day, two dungeons open up for you to explore.
In these dungeons, you earn special coins that you can swap for useful prizes at the Trader's Shop. These coins are obtained from a chest that fills up over time. The more levels you beat, the more coins you get from the chest. But remember, there's a limit to how many coins the chest can hold.
You can start exploring dungeons once you reach Guardian level 13.
