Utility
A spectral, floating hand appears at a point you choose within range. The hand lasts for the duration or until you dismiss it as an action. The hand vanishes if it is ever more than 30 feet away from you or if you cast this spell again.
You can use your action to control the hand. You can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move the hand up to 30 feet each time you use it.
The hand can't attack, activate magic items, or carry more than 10 pounds.
Would it be possible to summon this in somebodys bloodstream and just, stop the flow of blood throughout their entire body or would I need wall of force for that
Under Rules As Written, no, because the spell description says exactly what things you can do with the hand, and that's not one of them. Also, this is kind of a gray area but as a DM I would probably not allow summoning things inside of creatures in general.
