Cool Off

Cool Off is a reccuring Art in the Xenoblade series. It is Sharla's talent art in Xenoblade Chronicles. In Xenoblade Chronicles X, it is an art exclusive to the Bastion Warrior class. It is tied to the Gatling Gun weapons and Cross can use it once learnt by equipping said weapon no matter the class he currently is.

Xenoblade Chronicles
It can be activated at any time if Sharla's Talent Gauge is not empty, and will automatically activate if her Talent Gauge is full. While Cool Off is active, Sharla regenerates 3% of her maximum HP every second, but cannot move, attack, or use arts. Her healing and damaging Arts' power also depend on how much her Talent Gauge is filled.

Talent Gauge Effects
Sharla's talent gauge affects the damage and healing done by her arts, with damage increasing and healing decreasing as the talent gauge fills.

Xenoblade Chronicles X
In Xenoblade Chronicles X, it allows a Bastion Warrior to remove their debuffs and convert their current aura into TP if they have one. Secondary and Tertiary cooldown bonuses allow the Bastion Warrior to reuse the Art immediatly.
