Magic Items

Wondrous Item, rare (requires attunement by a cleric or paladin)
This amulet bears the symbol of a deity inlaid with precious stones or metals. While you wear the holy symbol, you gain a +2 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.

Weapon (any sword), rare (requires attunement)
When you hit a creature with an attack using this magic weapon, the target takes an extra 2d6 Necrotic damage and must succeed on a DC 15 Constitution saving throw or be unable to regain Hit Points for 1 hour. The target repeats the save at the end of each of its turns, ending the effect on itself on a success.
