Term: Recharge⟳

Recharge, or ⟳, is a mechanic for many creatures in the Creature Index. Once a creature uses a feature or action (often a big, defining one, like a dragon's breath weapon), it will go on a lengthy, Round based cooldown, going down at the start of each of that creature's turn or through Escalation⥣. Once it reaches 0, the creature can use that feature again, and the creature will often have ways to make the Recharge go down faster.
Features and Actions with Recharge will often read like this.

Recharge⟳: Once used, this action takes 1d6 rounds before it can be used again. This count goes down at the start of the Red Dragon's turn, and each time they critically strikes a target with a Natural Weapon.
