Janna Ability (LoL): Howling Gale

Janna summons a tornado that grows stronger over 3 seconds then blows along its path. It deals 60 / 85 / 110 / 135 / 160 (+35% of ability power) (plus 15 / 20 / 25 / 30 / 35 (+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.
