Nintendo is holding a new Spirit Board event in Super Smash Bros. Ultimate this week. The event kicks off tomorrow, January 7, and it introduces a handful of new Spirits based on the recent Zelda spin-off, Hyrule Warriors: Age of Calamity.

Three new Age of Calamity Spirits are making their debut as part of the event: Age of Calamity Impa, Master Kohga, and the Diminutive Guardian. All three will be appearing randomly throughout the event, and defeating them will net you extra gold as well as unlocking them for your own use.

The Age of Calamity Spirit event begins at 10 PM PT on January 7 and runs until the same time on January 12.
