Effects in the text
Volcanic Rupture
Ornn slams the ground, sending out a fissure dealing damage and slowing enemies hit. After a small delay, a magma pillar forms at the end location.
Effects in the text
WW
Bellows Breath
Ornn advances, breathing fire. Enemies hit by the final gout of flame become Brittle.
EE
Searing Charge
Ornn charges, dealing damage to enemies he passes through. If Ornn collides with terrain while charging, the impact creates a shockwave around him which deals damage and knocks up enemies.
Effects in the text
RR
Call of the Forge God
Ornn summons a massive elemental at a location which travels toward him with increasing speed. Enemies run over by the elemental take damage, are slowed and are made Brittle. Ornn can recast the ability to charge into the elemental, redirecting it in the direction he hits it, causing the elemental to affect any enemies it runs over to be knocked up, dealing the same damage and re-applying Brittle.
