Heat Gauge is a gauge located at the bottom of the screen. It is used to perform Distortion Drives, Astral Heats, Counter Assaults, Rapid Cancels and Crush Triggers. Player can gain Heat by hitting the enemy, making the enemy block an attack, taking a hit or blocking an enemy attack. The amount of heat gained per hit scales downwards as a combo goes on. The Heat Gauge resets to empty at the start of each round. After performing an ability that consumes 25% or more of the Heat Gauge, player will gain 75% less heat and auto heat gain will stop for a set amount of time. When players health bar is under 35%, his Heat Gauge will slowly gain Heat automatically at the rate of 1 unit per frame. Hakumen normally gains 3 units per frame, but when he has less than 35% health, he gains 4 units per frame. The heat meter will have a flashing icon when this occurs.
