Festival Kassadin

Festival Kassadin, part of the Winter Sports line, made its debut in February 2010 for 520 RP, placing it among the earliest reskins ever given to the Void Walker. The line leaned into a wintertime competitive-games theme across several champions at once.

These days the skin lives in the Legacy vault rather than the standard shop, so it only becomes purchasable again when Riot brings back legacy content during a limited-time event.
