Carnwennan's Cage Hand

From the maker of the Hand of Ages platform, including the Micromanage Hand, Rage Hand, Sage Hand, and several others comes another can't-miss addition to your arsenal.

This hand is incapable of opening doors or directly causing damage, but can interact with magical items. 

A spectral, mechanical, floating hand glowing a sunny yellow color 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 60 feet away from you or if you cast this spell again. This variant of the Mage Hand was designed with trapping in mind, able to create structures and contraptions at lightning speed with incredible ease. It is capable of generating 100 feet of rope or metal wire, it can transform into a cubic or cylindrical cage up to 6 feet high and 3 feet across, and can also launch individual tendrils of wire into surfaces from the fingertips. The hand will follow you until the spell ends or 1 hour elapses. The hand emits a cone-shaped beam of light similar to a lantern from the middle of the palm. 

Boosted variant- In exchange for spell slots,  specialized materials can be made using the hand if given enough time and if it has the capacity. The duration of the spell is also increased by 30 minutes for each level used. In its boosted state, the hand can be "switched off" to conserve the rest of its duration, hibernating while executing some certain functions and commands it's given.
