Skill Basis
Skill Basis
All characters have a Skill Basis modifier which is the 'foundation knowledge' your character has in all skills. This represents the fact that all player characters are exceptional, even in small ways, when compared to NPC's. The Skill Basis is the foundation number from which you calculate your skill rolls, in addition to adding in your stat modifiers, your ranks, magic bonuses, feat bonuses, and any other miscellaneous bonuses.
Your Skill Basis starts out as a +1 at first level, and every four levels goes up by any additional +1 (i.e., +2 at 4th level, +3 at 8th, +4 at 12th, and so on, to a maximum of +9 at 32nd level). Your Skill Basis increase reflects your greater knowledge of all things as you grow more world-wise, and can represent the 'school of hard knocks', the result of overhearing scholars talking in bars, hours of dedicated, solitary study, and many other things. Your Skill Basis increases in the same levels and for the same reasons that you get additional stat points as you level up: heroes are heroic, and their prowess is reflected in many ways.
