If you are looking for a gameplay guide for a character named Aria, the two most common results are:
: Build Phantom Power (via basic attacks, EX specials, or chain attacks) to unleash Level 3 plunge attacks.
Aria is an agent focused on high-scaling "bloom" damage during stun phases.
: Defense (aim for 2,000+), Critical Damage (target 250%–350%), and Effect Resistance (100%+).
