The following skins were released along with this patch. The first two skins' in-game appearance and splash art were recoloured on October 11th due to community feedback which claimed they looked too similar to the original skin.
The following skin was released with this patch, but was not available for purchase until Tuesday, October 11th, due to the fact that there was a particle error.
Arcanopulse: Fires a long-range beam of energy, dealing magic damage to all targets hit.
Locus of Power: Xerath anchors himself to a source of magical power, increasing the range of all spells and granting him bonus % Magic Penetration. Although he is immobilized while Locus of Power is active, his movement speed increases upon disabling the ability.
Mage Chains: Deals magic damage to an enemy and marks them with Unstable Magic. The next spell Xerath strikes this enemy with stuns them.
Arcane Barrage: Calls down a blast of arcane energy, dealing magic damage to all enemies in an area. May be cast up to three times before going on cooldown.
Ascended Form (Innate): Xerath feeds on arcane power, making him increasingly resilient to physical harm. He converts a percentage of his Ability Power into Armor.
