Amulet of the Arch's Light

While this appears as a normal holy symbol of Corellon, it is much more than that as it holds a spark of her Divine Power for her followers to wield. While attuned to this holy symbol, you gain +1 to your spell attack rolls and the saving throw DCs of your spells and the saving throw DCs of your Channel Divinity as well as the ability to 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 you finish a long rest. 

You can also gain two additional abilities from being attuned to this. You gain an additional Channel Divinity option, the Preserve Life option from the Life Domain. (Which is "As an action, you present your holy symbol and evoke healing energy that can restore a number of hit points equal to five times your cleric/paladin level. Choose any creatures within 30 feet of you, and divide those hit points among them. This feature can restore a creature to no more than half of its hit point maximum. You can’t use this feature on an undead or a construct"). Also, as a reaction a number of times equal to your Charisma modifier when a creature you can see within 15 ft. of you is hit by an attack, you can magically take that damage, instead of that creature taking it. This feature doesn’t transfer any other effects that might accompany the damage, and this damage can’t be reduced in any way.

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