Weapon (sling), uncommon (requires attunement)
You gain a +1 bonus to attack and damage rolls made with this magic weapon. While holding it, you can use an action to speak an insult into the sling's pocket, instead of loading it with a sling bullet. You then make a ranged attack with the sling. On a hit, the target takes psychic damage, instead of bludgeoning damage, and is affected by the vicious mockery spell (save DC 13; 1st-level version).
You don't need to attune to this weapon to use its properties if you already know the vicious mockery spell; a target hit by the sling in this way is affected by the spell as if you cast it, using your spell save DC and level.
