Hero Deck

The Hero Deck allows players to choose up to four heroes they can play as during a match. The Deck can be changed, but is locked during waves. This allows players to create specialized heroes, or to adapt as the situation changes.

You can not change the heroes in a deck during waves. You can change between your heroes to set up different defenses, and even combos. The hero that sets up a defense will determine its stats. Changing to a different hero after you've set up defenses will not alter the stats of the towers you already have on the map.

Changing the hero deck setup can be done in the hero menu and in the inventory
