It was assumed that the Sheik amiibo, arriving sometime in February with the other wave three amiibo, would have some type of functionality in the Zelda spin-off title Hyrule Warriors. There is now confirmation that the Sheik amiibo does have functionality in the game: it will unlock a weapon — specifically for usage with Sheik — rated three stars or higher, once per day.
This is incredibly similar to how the Zelda amiibo functions as well, so this doesn’t seem like much of a surprise. Link also works in a similar way, unlocking the “spinner” weapon once per day. Will you be picking up the Sheik amiiibo, if you can manage to snag it?
