Test Island

Test Island (テスト島, Tesuto Shima) is an exclusive map only accessible by using cheese method which is meant to be for beta test only.

Overview
This island can only be accessed by teleporting with its ID and set coordinates to a small island for test purposes.

The island consist of Goddess Ilias, Seraph Eden, two adult Promesteins, Tamamo, Granberia, Erubetie, Kitsune and Alice unsealed version.

Features
Talking to Goddess Ilias will result in a new game plus like similar to Reaper’s NG+ option after beating the game.

Difference will be that your companions and key items will be kept instead of a do over. This loophole can technically make the player play with Goddess Ilias and Alice at the same party, but there will be some bugs that may cause some events to not activate, or jumbled up making the other events never happened.

Talking to Tamamo will cause the player to unlock all like Jobs, Library, Items and more.

Talking to Granberia can allow the player to fight opponents like Micaela, Goddess Ilias, Dark Goddess Alice, Minagi or Chaos.

Talking to Erubetie can allow a party member to max their Race and Jobs to max.

Talking to Goddess Ilias can allow the player to start a new adventure similar to NG+ but there will be some bugs doing so.

Talking to the Two-Tailed Kitsune can warp a player to an event.
