Can a multiclassed Hexblade warlock/monk use their Hex Warrior class feature on their Martial Arts unarmed strike?

How about the Pact of the Blade feature to make their unarmed strikes magical?

Best Answer

No to both, unarmed strikes are not weapons

Hex Warrior says:

...whenever you finish a long rest, you can touch one weapon that you are proficient with that lacks the two handed property.

Pact of the Blade says:

You can use your action to create a pact weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it (see chapter 5 for weapon options). 

Unarmed strikes are not weapons so they cannot be used. Not to mention that Pact of the Blade works by creating a weapon out of nothing or by transforming an existing magical weapon, neither of which can apply to unarmed strikes.

Unarmed strikes are not listed as a weapon in the PHB after the errata which says:

Unarmed strike doesn’t belong on the Weapons table.

Also, Jeremy Crawford has clarified here:

Unarmed strikes have always been weapon attacks. Here's where the confusion comes in: your unarmed strike (fist, elbow, knee, butt, etc.) is not considered by the rules to be a weapon the way a longsword is a weapon. But the rules let you make unarmed weapon attacks anyway.

and here:

The rule on unarmed strikes is an exception: they can be used for melee weapon attacks, despite not being weapons.

Of course, monk weapons will work as usual and both benefits could be applied to those.
