Amulet of the Companion

This amulet bears the symbol of the Companion inlaid with precious stones or metals. 

While you wear this amulet, you can use your Channel Divinity feature without expending one of the feature’s uses. Once this property is used, it can’t be used again until the next dawn.

You also gain the ability to cast magic circle once per day without using a spell slot.

While you wear the holy symbol, you gain a +1 bonus to spell attack rolls and the saving throw DCs of your spells.

Notes: Bonus: Spell Attacks, Bonus: Spell Save DC, cleric or paladin of the Companion
