Mastermind Tips
This class has a ranged debuff play style. You want to focus on abilities and skills that increase ranged damage, your ability to debuff enemies, and increased duration.
Many Arts and skills acquired from these classes help make the enemy more vulnerable so that you and your team can deal more damage.
This is also the class branch you want to pick if you want to control enemies and the battlefield.
