"Trial" is a special dungeon that appeared in v1.4.0.
It is unlocked by conquering the Pandemonium.
The configuration changes every day.
Not only the configuration, but also the race, job, origin, and keystones at the time of the challenge will change randomly each day.
It can be used with setups that you do not own.
Even if you own a setup, equipped lab parts will not be applied.
Lab parts obtained upon clearing can only be obtained with setups you own.
You can obtain a unique reward, "Tag of Afterglow," on first clear each day.
The "Tag of Afterglow" you obtain can be exchanged for various items in the shop.
