Karthus Lightsbane

Karthus Lightsbane released in November 2016 under the Rift Quest banner, a thematic line built around adventuring parties battling through the Rift. The skin costs 975 RP and casts Karthus in a more heroic, questing light than his usual grim persona.

It remains available for purchase now, meaning there’s no need to wait for a sale or event — players can add it to their collection whenever they’re ready.
