High Summoner Galatea:
As I previously stated, in order to pass the Trials of the Summoner, you must battle and defeat six summoners. Before you challenge an opponent, you must have your own unique Arcana Cards created. Go and ask Lara of the town of Dion about making cards.
Do you have any other questions?
Ask about battle methods. Ask about Arcana Cards. Ask how to create an Arcana Card. Ask about potential opponents.
