The Choralier’s Companion (Saddle of the Cavalier)

Uncommon

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.

Fochlucan Bandore (Requires Atunement)

Uncommon

An instrument of the bards is an exquisite example of its kind, superior to an ordinary instrument in every way. Seven types of these instruments exist, each named after a legendary bard college. A creature that attempts to play the instrument without being attuned to it must succeed a DC 15 Wisdom saving throw or take 2d4 psychic damage. You can use an action to play the instrument and cast one of its spells: fly, invisibility, levitate, protection from evil and good, entangle, faerie fire, shillelagh, speak with animals. Once the instrument has been used to cast a spell it can’t be used to cast that spell again until the next dawn. The spells use your spellcasting ability and spell save DC. You can play the instrument while casting a spell that causes any of its targets to be charmed on a failed saving throw, thereby imposing disadvantage on the save. This effect applies only if the spell had a somatic or material component. This item is found in the Dungeon Master’s Guide
