Under each Primal's or boss's health bar, there may be a secondary gauge.

• • When the Gauge Fills:
    

    • Once full, the target becomes "Exposed" or "Unbalanced".
      

    • This puts them in a vulnerable state, allowing you and your team to unleash powerful attacks while they are stunned.
      
      

Important Note:

This mechanic applies to you as well. If your Primal becomes Exposed or Unbalanced, enemies can take advantage—so stay sharp in battle!
