Hey Vig,
What is up with the whole stunning fist being Fort save 10 + level +modifier - their level.
The system basically starts to break down the higher the opponents level. For example I'll use three situations:
MAM 4 - stunning fist vs fighter 2
Fort save 14 = (10+2(wis)+2(level difference).
MAM 8 - stunning fist vs fighter 6
Fort save 14 = (10+2(wis)+2(level difference).
MAM 12 - stunning fist vs fighter 10
Fort save 14 = (10+2(wis)+2(level difference).
For my example I'm saying that the stats all stay the same as a fighter can just as easily raise his Con as the MAM raises his Wis.
We can see that the saving throw remains the same but in reality it become easier for the fighter to make.
Situation 1: If the fighter has no Con he has to roll 11
Situation 2: If the fighter has no Con he has to roll 9
Situation 3: If the fighter has no Con he has to roll 7
Is this a flaw?
Am I reading something wrong?
