Baleful Hand

A spectral hand much like that of the mage hand forms from the hand or paw growing in significant size, taking up 2 cubic feet appearing in an unoccupied space of your choosing within range. The hand lasts until dispelled, or dismissed as an action. The hand vanishes if it is ever more than 80 feet from you or if you cast this spell again as a cantrip.

The baleful hand may immediately make an attack action upon casting. As a bonus action the caster may control baleful hand using it to do everything the normal mage hand can as well as pick up creatures, and objects equal to or less than 30lbs as well as make one melee attack within range using a weapon's attack and damage stats. Or if unarmed the baleful hand may attack using the caster's primary magic casting stat [ INT/WIS/CHA ] (1d6 + up cast level (see chart below) + modifier)

For each spell level above 2 the baleful hand grows an additional 2 cubic feet in size up to 18 cubic feet, gains an additional 30lbs to its weight limit up to a maximum of 240lbs, additional modifier to attack to a maximum of +14 + spell casting modifier, as well as up to 14 additional damage dice per the chart below.

Up cast to 4th level the baleful hand grows to such size that attacks cover larger area. Upon making an attack on a target the baleful hand may attack another target within 5 feet. Cast at 6th level and above the baleful hand may attack any amount of targets within a 5 foot radius. Cast at 8th level and above the baleful hand may attack any amount of targets within a 10 foot radius.

Up cast at 5th level, and above the baleful hand can use simple magic items and objects so long the caster may also use the magic item it is holding, or touching.
