Bardoq The Magnificent's Mighty Mage Hand! (Tm)

Your persistence in the fundamentals of magecraft has paid off at last! While other mages were foolishly toiling for mere god-like (or even godly) power, or training to increase their base abilities,  you were focusing on what really matters: the FUN-damentals! After following Bardoq The Magnificent's patented twelve-week correspondence course, (and signing away a non-zero percentage of your mortal soul), Your puny Mage Hand has evolved through rigorous (and dubious) training to become Bardoq The Magnificent's Mighty Mage Hand! (Tm)! Go forth and Hand-le all of life's challenges with Bardoq The Magnificent's Mighty Mage Hand! (Tm)!

•  You can cast Bardoq The Magnificent's Mighty Mage Hand without verbal or somatic components, and you can make the spectral hand invisible. Its strength is now equal to one of your own hands, and anything you could do with one hand, you can now do with your Mage Hand. 
• As a bonus action, you can use your Mighty Mage Hand to attempt any action you could do with one hand.
• The Mighty Mage Hand can be used to wield and attack with light weapon as a bonus action. This does not qualify for two weapon fighting or dual-wielding bonuses, but does count as an off-hand attack. 
• Spell and Cantrips with a range of Touch can be cast using the Mighty Mage Hand as a conduit.
