Amulet of Hidden Dreams

This amulet bears the symbol of a deity inlaid with precious stones or metals. This is only able to be worn by someone who is both a cleric and a rogue. While you wear the 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.
While wearing this amulet,  you can use your Channel Divinity to instead add 1d6 per cleric level to your sneak attack. 

Notes: Bonus: Spell Attacks, Bonus: Spell Save DC, cleric rogue
