The Psycorruptor and Mastermind Classes in Xenoblade Chronicles X are mostly focused on support and debuffing the enemy. This is viewed as a more advanced class tree than the others, but I think anyone can do it as long as you understand the game and how the classes work.
I’ll help explain this class and tell you all the arts and weapons they can use. For help with the base class Enforcer, or any of the base classes, check out my Base Class Guide.
This guide will go over the Psycorruptor and Mastermind class tree in Xenoblade Chronicles X including:

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.
