Character Advancement Rules
In this section I’ll list any special rules that pertain to character advancement.
At 4th level and every 4 levels thereafter, player characters may increase two abilities scores instead of just one. Both increases are by one point, and the two points may not go to the same ability score.
Player’s Handbook II p.191-199 ‘Retraining’ allowed with the listed costs (including a possible quest as well), ‘Rebuilding’ rarely allowed. Both on a case by case basis only. (double check for anything similar in Pathfinder).
