The fire below the mountain.
Passive - Living Forge & Master Craftsmen:
Living Forge: Ornn can spend gold to forge items for himself any time he's out of combat. For convenience, suggested items appear in a special on-screen menu. Ornn can also open the shop manually to build any item.
Master Craftsman: Ornn and his teammates have access to special upgrades for select items in the shop. Each player is limited to one of these upgrades.
Q - Volcanic Rupture: Ornn slams the ground, sending out a fissure that deals physical damage and slows enemies. After a small delay, a magma pillar forms at the target location, functioning like a tiny wall for a few seconds.
W - Bellows Breath: Ornn becomes unstoppable, shields himself, and belches out flames. These flames deal a portion of the enemy's current health as magic damage. Enemies struck by the final gout of flame become Brittle. Ornn's basic attacks knock back Brittle targets.
When Brittle, enemies suffer a portion of their maximum health as bonus damage when struck by immobilizing effects. Immobilizing effects also last longer when used on Brittle enemies.
E - Searing Charge: Ornn charges, dealing damage to enemies he passes through. If Ornn collides with terrain while charging, the impact creates a shock wave that deals damage and knocks up enemies. This ability destroys player-created terrain.
R - Ornn summons a massive fire elemental at a target location. It then travels toward him with increasing speed. Enemies run over by the elemental take magic damage and become Brittle.
Ornn can recast this ability to charge forward. If he strikes the elemental with the charge, he'll redirect it. The redirected elemental will then knock up all struck enemies, dealing the same damage as before and applying the Brittle effect.
