Gems and Trait Rerolls are important resources in this tower defense experience. Gems are the main in-game currency, which you can use to summon units from the gacha. The free diamonds offered by codes help you save time that would have otherwise been spent on clearing stages.

Trait Rerolls allow you to switch the traits of your characters. To do so, speak to Karoli and Justi in the lobby and choose the "Traits" option. You can have up to two traits on a unit, and each provides a different stat boost/s.
