A.K.A. "Project Babel: Bai Ze Chamber", occurred under the Lost Chapter Patch.
1) The Project Babel - Bai Ze Chamber consists of 3 levels. Each level has only 1 optional stage. In the optional stage, you can freely choose the combination of strategic objectives.
2) Each level can be challenged with up to 3 teams. You can only use the 1st team attempt each level at the beginning. When the 1st team has a clear record for each level, the 2nd team will be unlocked. When the 2nd team has a clear record for each level, the 3rd team will be unlocked. The record for each team's challenge level and members will be saved separately.
3) Each level contains 5 difficulty levels. Based on your selection, the final Strategic Level will gain different bonuses. Final Strategic Level = Strategic Level Selected x Difficulty Bonus Coefficient (rounded off).
4) There are three parts in the level: [Environmental Intelligence], [Strategic Target] and [Support Module] which will affect the battle.
Environmental Intelligence: Environmental Affixes in the battle. The challenge of this level will be affected by the Environmental Affixes.
Strategic Target: Difficulty Affixes in the battle, the selected Affixes will be added to the level to increase the difficulty.
Support Module: Buff Affixes in the battle, the selected Affixes will aid your members in combat.
5) After each successful challenge, the members used will be locked and cannot be used in other levels and form another team. The players can change the status of the members by "Clearing Record" or "Restoring Record".
Clearing Record: To clear the Strategic Levels gained by completing the level and unlock the members at the same time.
Restoring Record: Restores the level to the state before completion and regains the corresponding Strategic Levels. The members used to complete the level will be locked again.
6) According to the combination of Strategic Objectives selected in the challenge of each level, rewards can be obtained once the total Strategic Level for a single level or the accumulated Strategic Level has reached the requirement of the Challenge Mission.
7) Once you complete a level, you will get a collectible reward. The higher the Strategic Level you reach, the better quality the collectible will be.
8) The final Strategic Level reached by all of your teams will be shown on the Babel Tower Ranking.
