skillz

Pathetic --> Untrained --> Novice --> Adept all costs 1 skill point per step
Adept --> Expert --> Master costs 2 skill points per step

Five edges, with single-skill-point edges
Skill points (or I guess stats if they so choose - have to balance that out too) at every other level

up to 5 skill points at chargen --> 5 skills at novice
Assuming one skill point per even level, they could have two adept skills at level 4 with 3 novice skills. At level 6 they could have 3 adept skills. No one can have expert skills without taking the feat for skill ranks until level 8, and then the rest of their skills would be novice and they'd only have four of them max. At level 12 they could have tha expert skill be master, but they'd suck at everything else. In comparison, they could instead have 4 adept skills and 3 novice skills at level 12. I haven't figured this out yet for higher levels than that because I have to grab food.
