Tahm Kench Ability (LoL): Abyssal Dive

Dive down and then re-appear at target location, dealing 100 / 135 / 170 / 205 / 240 (+150% of ability power) magic damage and knock up all enemies in an area for 1 second. Hitting at least one enemy champion refunds 40 / 42.5 / 45 / 47.5 / 50% of the cooldown and mana cost. Devoured allies can be taken along for the ride (but can always hop out early).
