My character is a level one high elf rogue, so I picked mage hand as his high elf cantrip. When he gets to level three, I plan on picking the Thief archetype.
Can he use the fast hands bonus action to control the mage hand that he cast on a previous turn?
I think he should be able to because fast hands allows for the "use an object" action and I can't think of what other type of action controlling mage hand would be.
Best Answer
Mage Hand's description reads:
Fast Hands:
Presumably, this newfound dexterity is proper to the Rogue (i.e., the physical prowess of the PC), whereas Mage Hand is based on mental effort and the limitations of the spell. Hence, without a houserule, I don't think you can control Mage Hand using a bonus action.
As othniel2005 said, you would have to pick the Arcane Trickster archetype for that.
