Oceanic Sling

Ammo: sling bullet

This elegant weapon is adorned with engravings depicting leaping dolphins and drifting jellyfish. You gain a +1 bonus to attack and damage rolls made with this magic weapon, and you ignore the normal penalties on ranged weapon attacks while using this weapon underwater. While holding the weapon in front of you with both hands, you have a swimming speed of 30 feet. Additionally, while you hold the weapon, you can use an action to cast the water breathing spell. Once this property is used, it can't be used again until the next dawn.

Ammunition: You can use a weapon that has the ammunition property to make a ranged attack only if you have ammunition to fire from the weapon. Each time you attack with the weapon, you expend one piece of ammunition. The ammunition of a firearm is destroyed upon use. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon). At the end of the battle, you can recover half your expended ammunition by taking a minute to search the battlefield. If you use a weapon that has the ammunition property to make a melee attack, you treat the weapon as an improvised weapon (see "Improvised Weapons"). A sling must be loaded to deal any damage when used in this way.

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.
