The Girl Who Forgot Her Name also provides another avenue of spending your arma gems—Champion Medals. Talk to her about trading in arma gems for a tutorial on summoning Champions in battle. This system allows you to call in an ultimate attack delivered by a Final Fantasy Champion, provided you have enough Champion Gauge (see the Game Mechanics chapter of this book for details on storing Champion Gauge). As you progress through the main story, additional Champion Medals become purchasable. For now, you can opt to purchase the Warrior of Light’s Champion Medal to summon a devastating single-target physical attack. Alternatively, you can save your arma gems to complete two Intervention Quests instead (which opens up a huge potential EXP bonus).
