Rammus Ability (LoL): Powerball

Rammus channels for up to 6 seconds, tucking into a ball and starting to roll, gaining 25−39.17% bonus movement speed per second over the duration (depending on level), up to a maximum of 150−235% (depending on level). Powerball can be recast after 1 second during the channel, and does so automatically when the channel ends without reactivation or is interrupted.

Rammus stops rolling upon colliding with an enemy, dealing 100/130/160/190/220 (+100% of ability power) magic damage to all nearby enemies, knocking them back 125 units, stunning them over 0.4 seconds and slowing them by 40 / 50 / 60 / 70 / 80% for 1 second.

RECAST: Rammus ends Powerball.
