Last time I played FFXII I was fighting the mandragora group in the Sochen Cave Palace. I killed the Tomato Captain and King Allaune. However, after that, the remaining three mandragoras acquired 100% physical and magic resistance (i.e., they would parry all attacks and take 0 magic damage), making the fight unbeatable. I tried dealing with it for 20 minutes before giving up.
Is this a glitch, or is there some Garuda-like secret that I need to know?
