(Request) Make invisible knuckles for vanity

[Kitfox]

Good luck punching behemoth with your bare hands and expecting him to even notice it.
Punches could work in a man on man fight, but we're taking on primals, beasts, armored fighters, and mythological creatures. It's the old tale of how man can match up with the forces of nature not only with his (relatively weak) strenght, but because he can craft the right tools for any situation.

If a MNK is capable of effectively swinging around the Allagan Weapon, which looks like it weights 10-20 kg each, I assure you that without those things slowing him, a barrage of his punches would still hit like a full broadside from one of the Limsan ships.
