Initial Skill Points depend on your stat distribution. Strength, Dexterity, and Constitution contribute to the Combat SP pool, while Perception, Intelligence, and Charisma contribute to the Civil SP pool. Once the game starts, SP are gained by completing quests and vanquishing your enemies; high Intelligence increases the amount of SP gained.
