Adelaide's Arcane Arms

You call forth two spectral arms that hang over or behind you, which last for the duration - you decide what these spectral arms look like.

As an action, you can make a melee spell attack against a creature within 10 ft. of you with any arms you have. Roll a separate attack for each arm you use - on a hit, the target takes 2d8 force damage, and then that arm vanishes.

While you have at least one arm active, you can use your reaction to have any number of your arms attempt to block an attack roll against you, increasing your AC by 2 for each arm you use - you can use this reaction after you see the total for the roll, but before any of the effects take place. If the attack misses you, the arms you used to increase your AC vanish.

A creature can use this spell in mundane ways as well, such as carrying boxes or lifting a rock. Each active arm is able to carry up to 100 pounds, and uses your spellcasting ability for any ability checks they make.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you gain an additional arm per level of slot above 3rd.
