Argilla Ruins is the first dungeon accessible for Union of Fury characters. Found in the North region of Reikeuseu. The preferred level range is about 15-24. Anything higher and experince points will no longer be substaintual. There is no map for the Argilla Ruins. Your radar is useless and it is quite easy to get lost. The best way of navigating the dungeon is to party with veterans and simply follow them. There is one main and semi-complicated path that leads to both of this dungeon's bosses - Kargos - then Knight.
