|Q||Undertow||60 / 60 / 60 / 60 / 60 Mana||8 / 8 / 8 / 8 / 8||Olaf throws an axe to a target location, dealing 70/115/160/205/250 (+) physical damage to units it passes through and slowing them by 29/33/37/41/45% for up to 2.5/2.5/2.5/2.5/2.5 seconds. The further the Axe flies, the longer the slow lasts, but it is never less than 1.5/1.5/1.5/1.5/1.5 second.
If Olaf picks up the axe, the ability's cooldown is reduced by 4.5 seconds.|
