Betelgeuse's Unseen Hand

Three invisible hands of eldritch origin emerge from your back, shooting out 30 ft. in any direction. Each turn, you can move the hands up to 15 ft. as a free action. When a hand is within 5 ft. of a target, you can use it to attack as a bonus action - the target must roll a Dexterity saving throw or take 1d10 force damage. Each turn or time attacked, creatures within 60 ft. can roll a DC 23 Perception check, losing disadvantage on the saving throw on a success and automatically succeeding with Truesight. Disadvantage is also lost when particles can reveal where the hands are, such as rain or dust clouds.

As a reaction, targets who can see the Unseen Hand can roll to attack it as a reaction. The hands have an AC equal to 14 + your spellcasting modifier and 10 HP.

For each level the spell is upcasted, it creates an additional unseen hand, and gives you an additional bonus action that can only be used with this spell.
