How to quickly improve the level of Metaphorical Fantasy Archi State
The prototype gains A-EXP, which is the second value shown on the victory screen of a battle. Against most enemies in the game, you'll gain less A-EXP than normal experience points, so your archetypes will level up slightly slower. Each archetype can be upgraded twenty times, and upon reaching the maximum level, the character can summon the next archetype of the family, as long as it has been unlocked through that archetype's followers. Defeating enemies in the outside world is helpful, although only providing a small amount of A-EXP.
Other ways to get more A-EXP include:
Defeat the Elemental Man
Achieve an injury-free victory
Use Hero Spice, Hero Fruit and Hero Light Leaf
Elemental Trolls will not resurrect after being defeated, but will provide a large amount of A-EXP, MAG and Reeve. However, they will run away after only one turn in combat unless stunned. Other hero items can be used in any character's archetype, and are often obtained relatively commonly as loot in quests and dungeons. The Heroic Light Leaf is the best item as it provides 1,000 A-EXP to any archetype, and luckily, they can be obtained over and over again.
