Cheston goes down on all four and starts pounding the ground, heavily damaging and throwing all hostiles away from him. It increases his base movement speed by roughly 50% but prevents Cheston from using weapons or other skills. If used midair will give a surge of speed but will drain much faster, this is called 'rampage jump'.
It can also be used offensively to do damage to stationary bots or turrets, to trap a player in the corner, to attempt a ringout or to knock opponents away from friendly pros.
Leveling increases damage per tick and reduces cooldown.
