If youre going for realistic fighting weaknesses and strengths, there isn't much to say about capoeira. As far as I understand, it is great exercise and good fun - but its practicality in combat leaves something to be desired, and has a very long list of weaknesses. Not dissimilar from mcdojo Krav Maga.
However, if you dont mind the rationale (as you shouldn't, this is a fantasy world afterall) then consider reading some of the free pdfs on it. Im not sure which show fighting diagrams and breakdowns, but I found a few (specifically Capoeira: From Slave Combat Game to Global Martial Art) that could look up. Otherwise, YouTube will have a number of breakdowns on how it all works!
Good hunting!
