Ornn Ability (LoL): Volcanic Rupture

Ornn slams his hammer into the ground, sending a fissure in the target direction that stops early if an enemy champion is hit, dealing 20 / 45 / 70 / 95 / 120 (+ 1.1 per total attack damage) physical damage and slowing enemies hit by 40% for 2 seconds.

After a 1.5 second delay, an impassable magma pillar erupts at maximum range for 4 seconds.
