Ability modifier

From NWN2Wiki

An ability modifier is the bonus or penalty associated with a particular ability score. Ability modifiers apply to die rolls for character actions involving the corresponding abilities -- such as attack rolls, saving throws and skills. The modifier is also used with some numbers that aren't die rolls. A positive modifier is called a bonus, and a negative modifier is called a penalty.

The modifier is equal to +1 for every 2 points above 10 in that ability score (or -1 for every 2 full points below 11). For example, constitution 14 provides +2 hit points per level.

In addition, ability scores determine the number of bonus spells for spellcasters. The ability that spells relate to depends on the type of spellcaster:

In addition to having a high ability score, a spellcaster must be of sufficient level in order to gain any bonus spells for a given level.
Spellcasters must also have a 10 or higher in the appropriate ability score in order to cast any spells.
