Active:Rammus tucks into a ball and begins to roll for up to 7 seconds, constantly accelerating up to 140% bonus movement speed. Upon colliding with an enemy, Rammusknocks all enemies within 200 units back 100 units, dealing magic damage and slowing them for 3 seconds afterwards. This also ends Powerball.
While in this state, Rammus cannot attack or use Puncturing Taunt. Activating Defensive Ball Curl during its duration will end the effect after 1 second, and it can be cancelled instantly by re-activating Powerball.
