The fun thing about max Brave, Accumulate, Two Swords, and Martial Arts as a combo is that Martial Arts basically takes your base physical strength and uses it as the theoretical strength for your "weapon" (your fists), multiplied by your Brave as a ratio. Thus, Accumulate is far more useful if you've got Martial Arts; 97 Brave with (let's say) 15 strength means you've got a total power of 30, with two hits - this math isn't quite right, but bear with me - so that gives you a total power of 60 (sorta).
Every time you Accumulate, that means +1 strength, which with Martial Arts is actually sorta +2, and then with Two Swords is actually sorta +4 for every single Accumulate you do. And if you're doing this with Ramza and Scream, then you're also getting +1 speed out of the deal.
Also, Martial Arts' bonus to Monk action abilities gets more effective the higher your PA stat gets, so you also pretty much give Ramza the ability to full-heal himself and others with Chakra pretty quickly.
Even Accumulate and Martial Arts is pretty easy to pull off very, very early in Chapter 1; max Brave is something you should get on Ramza as soon as you possibly can (it's more of a Chapter 2 thing because you get Cheer, IIRC), and then just make a beeline for Two Swords. Ramza as a monk with Two Swords and Guts can basically cheese everything in the game immensely well while also healing himself incredibly effectively.
