Determine Bonuses

Source PRPG Core Rulebook pg. 15
Each ability, after changes made because of race, has a modifier ranging from –5 to +5. Table 1–3 shows the modifier for each score. 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. The table also shows bonus spells, which you’ll need to know about if your character is a spellcaster.
