Get a 25% damage boost on effective skills, or a 25% damage reduction from a non effective skill.

Example: Fire skills get 25% damage bonus on ice and nature enemies, while a fire battler gets a 25% damage reduction from ice and nature skills.

However, the fire battler receives additional 25% damage from water and earth attacks, while fire skills get a 25% damage reduction when used on water or Earth enemies.

 

Note: Light and Darkness do not resist each other but are effective (bonus damage) on each other.
