Arcane Professor Heimerdinger

Arcane Professor Heimerdinger draws its look straight from the Arcane series, giving the champion a makeover that borrows the show’s signature visual style. It launched in December 2024 as an Epic skin for 1350 RP and landed in the same stretch as a batch of other content inspired by the show.

The skin has since been shifted into the Legacy vault. That means it no longer appears in the regular store and only comes back during select promotional events. It includes one chroma, and collectors who keep an eye on vault rotations tend to watch for it.
