Yagura:SRD:Ability Scores
The Abilities
Each ability partially describes your character ("you") and affects some of your actions.
When an ability score changes, all attributes associated with that score change accordingly.
Nonabilities
Some creatures lack certain ability scores. These creatures do not have an ability score of 0—they lack the ability altogether. The modifier for a nonability is +0. Other effects of nonabilities are detailed in the ability's description.
Ability Scores
Abilities and Spellcasters
The ability that governs bonus spells depends on what type of spellcaster you are. In addition to having a high ability score, a spellcaster must be of high enough class level to be able to cast spells of a given spell level.
Ability Modifiers
Each ability, after changes made because of race, has a modifier ranging from –5 to +5. Table: Ability Modifiers and Bonus Spells shows the modifier for each score. It also shows bonus spells, which you’ll need to know about if you are a spellcaster.
The modifier is the number you apply to the die roll when your character tries to do something related to that ability. You also use the modifier with some numbers that aren’t die rolls. A positive modifier is called a bonus, and a negative modifier is called a penalty.

How To Determine Bonus Power Points
Your key ability score grants you additional power points equal to your key ability modifier × your manifester level ×1/2. Table: Ability Modifiers and Bonus Power Points shows these calculations for class levels 1st through 20th and key ability scores from 10 to 41.
