Let me put this way: anyone who completes the stage 2 trial is an absolute moron. You're losing 2.5m potential gil every dynamis run you fight ADL instead of farming currency. Multiply that by the number of times you'll need to kill him for every person in the alliance, and you could have completed every relic weapon up to level 99... instead glowing blue.

The auras are nothing more than a /point and laugh at how stupid someone is for actually having completed the trial.
