High Summoner Galatea:
This trial tests to see if you have the will and determination to become a Summoner. What must be done is quite simple. You must seek out and engage other Summoners in battle. Achieve victory against six opponents and you will prove yourself worthy and pass the test.
This may seem an easy task, but a battle amongst Summoners is fairly difficult and will test a Summoner's ability to control his or her summoned creature.
