Mr. Shifty's Trident (5e Equipment)
From D&D Wiki
Weapon (trident), legendary (requires attunement)
An elegant, brass trident that looks almost decorative.
You have a +1 bonus to attack and damage rolls you make with this magic weapon, and attacking with it at long range does not impose disadvantage on your ranged attack rolls. When you use it to make a ranged weapon attack, each creature in a line 5 feet wide that extends from you to the target's location, excluding you and the target, must make a Dexterity saving throw. The DC for this saving throw is equal to the attack roll. A creature takes 4d6 piercing damage on a failed save and no damage on a successful one. On a hit, the target takes damage from the trident plus 3d6 piercing damage.
You can use a bonus action to teleport to the trident's location.
