Janna Ability (LoL): Howling Gale

Janna summons a tornado that grows stronger over 3 seconds then blows along its path. It deals 55 / 90 / 125 / 160 / 195 (+50% of ability power) (plus 10 / 15 / 20 / 25 / 30 (+10% of ability power) per extra second charged) magic damage and knocks up for 0.5-1.25 seconds. The distance, damage, and knock up duration increase based on how much the tornado grew.

Janna can recast to send the tornado early.
