Amulet of the Devout

Requires attunement by a cleric or paladin. While
you wear this holy symbol, you gain a +1 bonus
to spell attack rolls and the saving throw DCs of
your spells.
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.
For we live by faith, not by sight.—Corinthians 5:7
