Magic hand can be used for nut punches
So we were in a close quarters fight, our rogue gave up his awesome plan to throw an oil soaked net on top of the group we were fighting and then lighting it on fire to punch a guy in the nuts with his magic hand.
Rogue: “I use my magic hand to punch that guy in the nuts to make him drop his weapon.”
Everyone else ooc: “No go with your other plan, you’re going to waste your attack!”
DM: “Okay, roll an attack.”
Rogue: “…I rolled a nat 20.”
DM: *after laughing for a solid 5 minutes* “Okay, you punch him in the nuts for 3 damage. He screams and drops to the ground. He drops his weapon to put his hands over his nuts.”
