Amulet of the Storm

This silver amulet has a small sapphire dolphin set in the middle. 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, whenever an ally within 10ft makes a successful melee attack, you may spend a reaction to add call down lighting to empower their attack. Roll a number of d6s equal to your proficiency bonus and add them together, the attack deals that much additional damage. Once this property is used, it can’t be used again until the next dawn.

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