Upon dying, Karthus enters a spirit form that allows him to continue casting spells.
Karthus unleashes a delayed blast at a location, dealing damage to nearby enemies. Deals increased damage to isolated enemies.
Karthus creates a passable screen of leeching energy. Any enemy units that walk through the screen have their Move Speed and Magic Resist reduced for a period.
Karthus passively steals energy from his victims, gaining Mana on each kill. Alternatively, Karthus can surround himself in the souls of his prey, dealing damage to nearby enemies, but quickly draining his own Mana.
After channeling for 3 seconds, Karthus deals damage to all enemy champions.
The harbinger of oblivion, Karthus is an undying spirit whose haunting songs are a prelude to the horror of his nightmarish appearance. The living fear the eternity of undeath, but Karthus sees only beauty and purity in its embrace, a perfect union of life and death. When Karthus emerges from the Shadow Isles, it is to bring the joy of death to mortals, an apostle of the unliving.
Karthus was released on July 13, 2010. Players could purchase them with Riot Points or Blue Essence as soon as it dropped in-game.
Karthus is primarily played in the Jungle lane and falls under the Mage class. The champion's kit and playstyle make them most suited for it, where they can maximize their impact throughout the game.
Currently, there are 10 Karthus Skins available in the game. This includes all cosmetic variants released since their launch, the base skin is not included.
Karthus costs 1,575 Blue Essence or 790 Riot Points. You can purchase them from the in-game store using either currency. Blue Essence is earned through the battle pass and disenchanting champion shards, while Riot Points require real money to obtain.
