KMST 1.2.417 - Part Time Jobs

Ah i see, then perhaps it is:
B - 31+
A - 71+
S - 121+
SS - 200

That probably fits better given the fact that Cygnus can only reach A


I wonder, does that mean High Max HP/MP = Higher damage? Thats pretty awesome for making a HP warrior i guess xD

Nope, it's:
30~69 rank B
70~119 rank A
120~199 rank S
200 rank SS

with the exception of KoC will be rank A even if they're 120.
