Character creation starts with the generation of 6 ability scores which determine the type of character class that a player will play. Each ability score is determined by rolling 3d6.

Strength measures your character's muscle and physical power. When using a melee weapon, you can use your Strength Bonus to modify your Base Attack Bonus.

Dexterity measures hand-eye coordination, agility, reflexes, and balance. When using a ranged weapon, you can use your Dexterity Bonus to modify your Base Attack Bonus.
