The Attacker starts the fight with a Thermostat value of 10.
Landing Basic Attacks increases the value by 1 for each hit.
Blocking an attack, or activating a Special Attack decreases the value by 2.
If the value reaches 0, the Attacker is inflicted with Coldsnap, if the value reaches 20, the Attacker is inflicted with Incinerate.
If either of these are triggered, the Thermostat value is reset to 10.
