The Choralier’s Companion (Saddle of the Cavalier)

Uncommon

Wondrous Item, Minor, Uncommon Table B, Tier 1-4, 8 TCP While in this saddle on a mount, you can't be dismounted against your will if you're conscious, and attack rolls against the mount have disadvantage. Any mount that wears this saddle possesses a phenomenal gift for singing—the song selection, frequency, and volume depends on the temperament of the mount, but it’s beautiful and almost always entertaining. This effect does not grant any additional languages to the mount.
