High Pressure

High pressure is a short range attack, the more damaging of the short range abilities the Frost has. When you shoot the shell that hits the target does no damage. When it hits the target orange/yellow fire balls expand out, then they close back into the initial shell. The more you upgrade the High Pressure ability the further the fire balls travel out and the more damage they do. If there are two targets and you hit the one lower then the other one the fire balls can travel through terrain and hit an enemy.
