Gauntlets and a monk's unarmed strikes

[IcyCool]

But that feat chain is exactly what you would need according to my interpretation. I'd personally switch the order because you'll get far more advantage that way and it makes more sense to me.

Ah, note that I said Spiked Gauntlets (a light, simple weapon). What I was unsure about was, should I also include Gauntlets (an unarmed strike). It seems like there might just be too many issues with that, so I just focused on Spiked Gauntlets. I went with the same style as the Eberron feats that let you use a non-monk weapon as a monk weapon (Serpent Strike, Whirling Steel Strike, etc.). I tried to avoid letting a monk get around its inherent limitations with a single feat, hence the feats placement in the chain.

Metal Fist Strike

Benefit
You may substitute your unarmed strike damage for the spiked gauntlet damage while still benefitting from the spiked gauntlet's enhancements and special materials.

You must have at least one hand free to use this feat.

Normal
When attacking with spiked gauntlets, you do base 1d4 damage as a medium character, not your monk unarmed strike damage.[/sblock]

Good proposed feats, IcyCool.
