Astral Hand

You create a replica of your own hand-formed of shimmering, translucent energy originating from your own hand. The hand lasts for the spell's duration, and it moves at your command, mimicking the movements of your own hand.

The hand is a material projection formed of astral forces. It is incorporeal and has hit points equal to half your hit point maximum. If it drops to 0 hit points, the spell ends. It has a Wisdom of 10 + your WIS modifier and a Charisma of 10 + your CHA modifier. 

When you cast the spell and as a bonus action on your subsequent turns, you can move the hand up to 30 feet and then cause one of the following effects with it.

Mental Pugilist. The hand strikes one creature or object within 5 feet of it. Make a melee spell attack for the hand using your game statistics. On a hit, the target takes 4d4 psychic damage.

Forced Projection. The hand attempts to push a creature within 5 feet of it in a direction you choose. Make a check with the hand's Charisma contested by the Wisdom check of the target with disadvantage. If you succeed, the hand pushes the target's astral body out of its material body. The target falls unconscious until they succeed a WIS check DC 15.

Mind Vice. The hand attempts to ensnare the astral body of another creature within 5 feet of it. You use the hand's Charisma score to resolve the action against the target's Wisdom check. The target becomes charmed while its astral self is held. While the hand is holding the target, you can use a bonus action to have the hand crush it. When you do so, the target takes psychic damage equal to 1d4 + your spellcasting ability modifier. The target can attempt to make a Wisdom contested check against the hand to escape the hand's clutches.

Psychic Guardian. The hand interposes itself between you and a creature you choose until you give the hand a different command. The hand moves to stay between you and the target. Any magic attacks the target attempts to make towards you the hand will intercept and extinguish. Every attack extinguished only consumes hit points.

At Higher Levels. The damage from the clenched fist option increases by 1d4,  and the damage from the grasping hand increases by 1d4 per spell level.
