Ive been getting a lot of questions on max stats. Here is a small chart that shows when each of your stats can be taken higher. Remember, you need to use max_stat eq to do this.
level Class Stat ordering
40 prime 19, 18, 18, 18, 18)
2x40 20, 19, 18, 18, 18);
3x40 21, 20, 19, 18, 18);
4x40 22, 21, 20, 19, 18);
5x40 23, 22, 21, 20, 19);
6x40 24, 23, 22, 21, 20);
7x40 24, 23, 22, 21, 20);
8x40 25, 24, 23, 22, 21);
