Olaf's attack speed increases by 1% for every 1% of his missing health.
Range: 400 - 1000
Cost: 60 mana
Active: Olaf throws an axe in a line to a target location, dealing physical damage and slowing enemies it passes through for between 1.5 and 2.5 seconds, depending on the distance the axe has travelled.
The axe remains at the target location until Undertow is off cooldown. Olaf can pick up the axe to reduce Undertow's cooldown by 4.5 seconds. If the axe would land inside terrain, it will instead stick to the wall.
Vicious Strikes will increase all healing effects targeted at Olaf. This will stack additively with Spirit Visage. However, it is worth noting that Spirit Visage will not increase healing effects sourced from other champions (such as an allied Astral Blessing), while Vicious Strikes will.
Vicious Strikes has no cast time and it will not interrupt previous orders.
The amount of attack speed granted dynamically adjusts over the 6 seconds.
Cooldown: 12 / 11 / 10 / 9 / 8
Cost: 21 / 34.5 / 48 / 61.5 / 75 (+12% AD)health
Active: Olaf attacks with such force that it deals true damage to his target. The ability's cost is equal to 30% of the damage dealt and the cost is refunded if Reckless Swing kills the target.
Olaf's basic attacks will reduce the cooldown of Reckless Swing by 1 second.
