Dungeon

The dungeon is unlocked once you have cleared Chapter 1 (3-10). Elemental Cores can be acquired from the Core Dungeon, once a day. The available elemental cores will vary per day so it will be a good practice to visit the dungeon at least once a day to secure a core. The star rank of the core you’ll get will depend on the dungeon’s difficulty level.

Normal difficulty yields 3-star Cores while Hell yields 4-star cores. The Super Core Dungeon follows the same mechanics. Normal difficulty yields x10 Super Core Fragment while Hell yields x20.

You can enter this instance for free once a day. This attempt is used regardless if you’re successful or your party gets wiped out. A Free Admission Ticket or 350 Rubies are needed to enter again after the daily free attempt has been used.
