Tonic

Tonics are a type of consumable that allows a player to change their form temporarily. All tonics come in two versions: single-use and infinite-use (differentiated by the infinite-use version bearing a sleeve with the infinity symbol on it). They can be acquired in a variety of ways, including special events and from the Zaishen Chest. Only one Zaishen Chest tonic is available at any given time; every month, the current Zaishen Chest tonic is replaced by the next one in order, until a year passes and the cycle begins again.
