Wait...what's Kraken doing THERE?
 

Black Belts were next to useless. Their upgrade class ate Knights for breakfast and were cheaper to boot.

its just supposed to be a random moster with tentacles
assume its a marlboro for now until Brian says ootherwise

I can only assume that's not supposed to be Kraken in particular, just some tentacled monster. Like Ultima said.
Actually, a Black Belt gains absolutely nothing in the transition to Master. Since the class change itself does not increase your stats at all, the only things that a character gains are the ability to use new equipment and learn new spells. A Master still cannot learn any spells, and doesn't rely on equipment to fight anyway. Basically, there is no difference between a Black Belt and a Master.

Didn't a Master get more attacks than a Black Belt?

YES he did. Thus making him hit substantially harder. Now I'm not sure about how origins has it, but it was this was way in the original. Never call BB useless. He's a beast. At Level 8 he hits harder and sooner than your fighter does. His only weakness is no armor. And you are overanalizing this Blue mage. That was just some silly joke that Brian wanted to make about sexual organs.

Honestly, this is going to feel like I am being crucified.

So the Master gets more attacks? That is true, however...
-Every other class can use magic.
-The Master can't take hits worth anything.
-He does not have the amazing power of the BW.
-He does not have the healng capabilities of the WW.
-He does not have the awesome defense Knight.
-He does not have the speed, defense, and luck of the Ninja.
-He also does not have the versitility of the RW.

A few of these may have been exagerations, but I have never seen a good use for the Black Belt or the Master any time I have played the game's. I realize the Meistro's (spelled wrong) point was that he does get something after class change, but it is insignificant compared to the other classes. I don't really believe this should become an argument, but they don't seem to have many good traits.

Which is funny that BB was the deus ex machina until he got killed by Kary. Which in itself was funny since she did it in one hit, as BBs have bad defense.

BB can't defend for crap is a true statment. But if your looking for raw consistant damage output through the whole game go with BB. My team was always Fighter BB RM and either WM or BM depending on whether I felt more agressive at the time. And at the beginning BM sucks bad. And at the end were all of his spells but one are useless he isn't your best person there either. If I had to choose the worst character game wise, I'm going with theif. Their lack of Attack and defnse isn't masked up enough by their luck and speed. And by the time they get black magic most thing in the game have too much HP and resistance to do anything. But the ninja looks considerably more badass than the master.

And about the no spells thing, you can always just give him one of the umpteen billion items with a spell use. But the point is BB/Master hits harder than anyone. Fighter/Knight does almost as much damage and has more defnese and HP. But at the later point of the game Tough fights are normaly the ones were the monster does nothing but cast some god spell taht hurts your whole team and magic doesn't really hurt him(cept for nuke). Then comes trusty BB/Master to hit him 16 times and a half dozen crits. The crit rate of BB is only slightly matched by thieves and their uncanny luck. But still BB is always one of my characters. And the cheapness factor helps through about half the game. After the next half it doesn't matter.
