Dart of Destiny

You cast a magical dart into the air. The dart can target any creature you know that is on the same plane of existence. It magically travels in a straight line towards the target, passing through any obstacle in its way, and will reach them in exactly one hour regardless of the distance. If the target leaves the plane, the dart vanishes. The dart deals 1d4 + your spellcasting modifier piercing damage to its target.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d4 for each slot level above 2nd.
