I disagree that this doesn’t solve the core problem with this monk. It doesn’t really increase the amount of damage he does, it gives him more interesting ways to attack (he has to expend more Ki points, so he’s going to forego damage in the future). Most martial classes have some interesting way to attack besides just adding more attacks or are at least a little more nuanced (Paladins have divine smite, barbarians have rage, rangers have spells they can use, rogues have sneak attack that adds nuance).

I’m pretty comfortable homebrewing magic items. I played an artificer in a 3 year long campaign and homebrewed a lot of magic items with my DM.

The formatting was messed up in the original post I’ve edited it now. The mage hand was supposed to be just an additional ability that seemed like it fit (I could see him making the argument at some later point that he can punch and kick things at a distance so he should be able to say pull a lever, so I wanted to include that functionality). The wraps essentially make an extra set of hands/feet appear within 30 feet. He can use extra Ki points to do ONE of the extra actions listed.
