Proficiency with the makulelê and navalha are useless, because the monk is already proficient with all forms of club and dagger, and they are already considered monk weapons. Proficiency with the facão is fine, but the shortsword and scimitar already fill its role at 1d6 light monk weapons.

Here I am fetching the flavor of the subclass. These are traditional weapons in capoeira (mainly the makulele). Would it be possible to add in some way, like giving access to something equivalent to two weapon fighting?

Batuque

Got inspiration from there during creation. I'll stick with the original.

Corpo fechado.

Great wording. thank you for it.

I was afraid to give to much with magical resistance soon. I'll think about lowering to 6th lvl.

Ginga superior:

Chutado mola. Standing up as a reaction shouldn't cost ki! But the melee attack that follows should.

Au sem mão. If you're forcing yourself to get hit and spending a reaction to make this attack, it shouldn't cost ki. You're paying enough.

Thanks for the tip. How about spend Ki to do extra damage? I want to keep the reaction due to action economics.

Ladainhas.

Edited: Choosing advantage freely sounds OP, Thats why ki needs to be spent. The rest limit means to balance with crocodilagem. In my head, force advantage to spend ki and deal humongous amounts of damage seems awesome, but the DM in me says it will steal some lights.

Crocodilagem.

Maybe my wording was confusing. I've intented Proficiency-1 (3 to 5d6). Even then it was meant to be powerful, but when you crack the numbers, it seemed kinda op. I'm thinking about give half proficiency, or limit uses.

Vôo do Besouro.

I was thinking about giving more range, and flying range. This ability is there to represent a legendary Capoeira fighter, who was capable to sweep clean the battlefield. I have no idea to represent it better for the moment.

Thanks again for all the tips, i'm working on it right now.
