Junkyard/Exploration

Unit EXP Guide
In order to gain the maximum amount of experience points possible, you must win all monster encounters available until obtaining a certain amount of gil from each of the two zones. You can open the menu to keep track of the amount of gil you obtained from the dungeon. Because the amount of gil you can collect is predetermined, it will indicate your progress in defeating all available monster encounters.

If you want to clear the map completely: Note: The off-map path leading to Treasure Chest #5 counts as Zone 2
 * Stay in ZONE 1 until you have 4,200 Gil.
 * Full Steal: 8,400 Gil.
 * Proceed to and stay in ZONE 2 until you have 10,092 Gil.
 * Full Steal: 20,184 Gil.
 * Defeat the boss.

You should conclude the dungeon exploration with a total of 10,687 gil and 69,400 EXP.
