The Stagger Effect Pt. 2
|Stagger 15 enemy types||Chapter 3||ATB Boost Materia|
You'll pick this up in Chapter 3 and once again, this is a rather simple one. You won't be able to auto complete this as soon as you receive it however as it's impossible to encounter more than 15 types of enemies before Chadley first hands you the request.
As for the task itself, always use Assess on new enemies (or check out the Enemy Intel section of this very guide) and target their weaknesses, this will Pressure them allowing you to follow up with the Focused abilities (Thrust, Strike, Shot) to Stagger them.
