Ancient Blade

are NaN Items in.

Location and Uses
NaN Ancient Blades are NaN Materials. They can be TotK: to a weapon or arrow to increase its attack power by 50, but will break after the first hit, and will disintegrate normal NaN Enemies on contact in the same way as NaN Ancient Arrows in.

They can be found in various NaN Treasure Chests across TotK:, as well as bought from a TotK: in the TotK: once the "TotK:" TotK: has been completed.
