Atlantean Weapon (5e Spell)
From D&D Wiki
|Casting time:||1 Bonus Action|
|Duration:||Concentration, up to 1 hour|
You imbue a weapon you touch with the elemental power of the deep blue sea. Until the spell ends, the weapon emits bright light in a 30-foot radius and dim light for an additional 30 feet, and attacks made with the weapon while underwater are not made at disadvantage. In addition, weapon attacks made with it deal an extra 3d6 water damage on a hit. If the weapon isn't already a magic weapon, it becomes one for the duration. A creature that wields the weapon and is friendly towards you has resistance to acid, fire, and water damage.
