Seeking Orb

Spell Lists: Sorcerer, Wizard
2nd-level evocation
Casting Time: 1 Action
Range: 5 feet
Components: V, S
Duration: Concentration, up to 1 minute.
You create a tiny orb of pure arcane energy that hovers within range, and designate a target creature within 120 feet. For the duration of the spell, at the end of each of your turns, the orb will move 30 feet directly toward the creature. If the orb reaches the target, it will detonate dealing 6d4 force damage to the target and ending the spell. If the orb does not reach the target before the spell ends, it fades away without dealing damage.
