Arrow of Seeking

Weapon (arrow), rare

When you make a ranged attack with this arrow, you don’t make an attack roll for the attack, but instead choose a target you have seen. If the target is within 600 feet of you, the arrow flies unerringly toward it, moving around obstacles and ignoring cover. If the arrow reaches the target, it must succeed on a DC 17 Dexterity saving throw or take damage as if it were hit by the arrow.
