Hmm, I don't think there are any more characters who can use any of those special stat growth rates in Suikoden II. They have definitely tried it with Viktor and Gremio, and suffice to say, Viktor's STR stat (A in hex) worked but not Gremio's (C in hex). IIRC, Viktor's HP growth in Suikoden I is one of those special growth rates, namely 0A in hex, but in SII, they changed his HP growth rate to 06 since he joins Riou's party much later than when he joined Tir's.You know there are 2 unused stat growth (B and C hex) that get better at level 60-99. So i actually think maybe Konami have a plan to make some "late bloomer" character, i mean we already have Viktor who's "early peaker" (A hex in stat growth).
So what do you think? maybe a char like meg, millie, bolgan, tuta should have this stat growth instead.
Actually Gremio does use this in Suiko 1. His strength increases normally from 1-20 and then again from 60-99, with 20-59 being his "dead levels" of only gaining 1 or 2 strength. This is why he's so weak when you lose him around level 33 or 34.
As far as I know, he's the only example of this.
