Spiral Abyss

A massive underground city constructed by an ancient civilization long gone. To this day, the purpose of this underground city remains unknown. Its structure is divided into the "Abyss Corridor," which connects worlds, and the "Abyssal Moon Spire," which leads to the unknown. It is now collectively called the "Spiral Abyss"... It is said that many secrets and treasures that have been long forgotten by this world lay buried within...

Monsters and humans alike flock to the tower in search of the secrets and treasures it contains. Challenge different floors of the tower and defeat the opponents within to win Abyssal Stars. Do this, and the Spiral Abyss may yet look upon your hard work and bestow rewards upon you.

The Spiral Abyss is divided into floors with each floor containing 3 chambers. Each chamber has 3 challenges with increasing difficulty.

Abyssal Stars will be rewarded upon completing the challenges. The 3 chambers of each floor must be cleared with a minimum of 6 Abyssal Stars in order to proceed to the next floor.

There are two ways to get the Abyssal Stars: by clearing the challenge within the requested time, or by defending the Ley Line Monolith from enemy attacks. Once the stars are obtained, they can no longer be lost nor will they affect obtaining the stars of another challenge or floor. You can also check the progress and statistics of the previous 12 months.

The Spiral Abyss is composed of two parts: the "Abyss Corridor" and the "Abyssal Moon Spire."

Clear all 8 floors of the Abyss Corridor to unlock the Abyssal Moon Spire.

The Abyssal Moon Spire will reset itself every month, with a new Lunar Phase occurring on the sixteenth day.

However, the generous treasures found in the Abyss Corridor which connects the world to the Abyssal Spire will not change or reset over time.

There are several restrictions in the Spiral Abyss. When challenging 3 chambers consecutively, you cannot:

• Consume food or other such items

• Change party members

• Change artifacts or weapons

• Level up or ascend characters.

In addition, each floor in the Spiral Abyss has different Ley Line Disorders.

It can give buffs or debuffs to characters, opponents, or both. In order to complete the challenge more easily, you should always take the Ley Line Disorders into consideration.

Challengers will receive recognition from the depths of the Spiral Abyss. This recognition comes in the form of a buff that assists you in battle.
The blessing in the Spiral Abyss changes every month and provides a range of buffs. You can check the current buff in "Blessing of the Abyssal Moon."

In addition, at the start of each chamber, you can choose to receive one Benediction of the Abyss. Different benedictions have different effects and durations:

Effective this floor: Effect lasts until entering the next floor.
Effective this chamber: Effect lasts until entering the next chamber.
Effective immediately: Effect starts immediately.

Choosing the right benediction according to your party composition will help you complete the challenge more easily. You can also take advantage of the fact that the cards are renewed every day.

It is said that some floors in the Spiral Abyss will diverge into two paths. To dive deeper, you must split your party into two groups...

Certain chambers will be divided into first and second halves. To clear the chamber, you need to split your party into two groups and clear each half separately. You cannot have the same characters in both groups.

Clearing the Spiral Abyss gives you generous rewards. Clearing each chamber for the first time allows you to receive the "Chamber Bounty." Earn enough Abyssal Stars in each chamber to collect the "Star's Bounty." You can check the rewards in the Reward Preview.

With the start of a new Lunar Phase on the sixteenth day of each month, the Abyssal Moon Spire's rewards will reset, which may also cause a new period of Blessing of the Abyssal Moon to begin.
Abyss Corridor rewards will not be reset over time.

Additionally, there are two permanent events through which you can obtain the characters or their Stella Fortuna and Masterless Starglitter if you already have them.
