Event Overview

Progress through Main Story Chapter 10 and challenge the score battles to earn rewards such as Dimensional Crystals.

■ Score Battle

During the event, you can challenge score battles of varying difficulties.

These battles do not consume Stamina and are unlocked by progressing through the new Main Story chapter.

Please check the event screen for the specific unlock conditions for each difficulty.

In score battles, your performance is evaluated and scored based on three criteria: total DMG taken until victory, number of rounds elapsed at victory, and number of Core Exposures. Scores are ranked from C, B, A, to S. (No score will be awarded for a defeat.)

Your current highest score can be viewed on the event screen. For reference on further increasing your scores, please check the breakdown for each criterion on the Result screen.

There are two types of rewards related to score battles: first-clear rewards and mission rewards, which are earned by achieving a certain score.

■ Stage Effects

The New Chapter Event features unique stage effects.

Utilize the stage effects and push for the highest score.

■ Missions

You can earn rewards and titles by clearing various missions.

Main Story Chapter 10 Release Celebration Login Bonus

In addition, you can get valuable items such as Dimensional Crystals, THE GAME Gacha Tickets, and Stamina Jellies.
