The Hand is a mythical item which is said to hold the true power of the human soul. It is a floating hand covered in a white glove, which can even walk on land or swim. The Hand can be killed, but respawns after 1d6 days undamaged. While it is no more than 30 ft away from at least one party member, it has two major powers:

The first power is his speed and strength: it can be commanded by using a bonus action or a reaction (but not both, and only one time per round per character) to retrieve, pass or use an item between party members, given that the item does not weight more than 100 pd. (weapon can be used only if one-handed, and it uses a +6 mod to hit and +3 to damage)

The second power requires attunement: each attuned member can use one time per day the spell Bigby's Hand, without any kind of component except for verbal one. The Hand teleports to the target and uses only one action, after which the spell ends. It uses +7 to hit and +4 to damage.

The Hand's Proficiency scales with the party's.

Notes: person. The attunement is used to unlock the second power of the Hand, and it can be attuned to more than one person.
