Image: Push Square

The Forgotten Hall, found on the Astral Express, consists of different combat gauntlets, each with unique completion conditions which, when fulfilled, unlock stars. These stars can then be traded in for rewards, including Stellar Jade. Each stage in the Forgotten Hall has unique effects and some are afflicted with Memory Turbulence, which alters the dynamics of the battles with unexpected buffs or debuffs. As such, you may want to consider selecting your team specifically based on these factors, as smart decisions will give you a distinct advantage in battle.

Each stage of the Forgotten Hall will need to be completed within a set number of cycles, or turns, and if you exceed the maximum limit then you'll fail. Conversely, if you manage to keep your number of cycles below the designated threshold, then you'll earn more stars, which will contribute towards you earning your rewards quicker.

It should be noted that the Forgotten Hall operates outside of the core game, and thus Equilibrium Levels do not have an impact on the difficulty of the enemies you'll face. Furthermore, once you start a stage you won't be able to access traditional systems, like party setup, your inventory, and character levelling. For the later stages, you'll have to setup two different teams, and we've included the recommended Elements you should target in our guide below.

How to Earn Stars

In order to earn stars in the Forgotten Hall, you'll need to fulfil the completion conditions of each stage outlined in the list of objectives above. You can earn a maximum of three stars for each stage, and these stack, so you can earn all three in one attempt, for example. You can then exchange any stars you've earned for rewards, which include crucial currencies such as Stellar Jade.
