Characters selected in one Room cannot be used in other Rooms. Save characters for different stages and form your teams carefully.

How to Beat Room 1

Be Ready to Parry

Scorpse Incoming Attack
The Scorpse likes to launch attacks in succession, so be ready to parry multiple hits within a short period using Defensive Assists.

Use Attack Agents

The effects in Room 1 work best with Attack Agents due to the increase in CRIT DMG. Rupture Agents can also work here, but they are better suited for Room 3.

Ye Shunguang is the top choice here as she deals damage that the boss is weak to. The free character Zhao also works extremely well in this room due to her ability to activate Ether Veil and synergy with Attack Agents.

How to Beat Room 2

Use Dodge Counter for Movement

Yanagi Dodge Counter
The Miasmic Terror Raptor will often retreat to the other side of the arena, putting a significant amount of distance between the two of you. When it does this, you can dodge its long-range attacks and perform Dodge Counters to propel yourself towards the boss to save some time.

Use Anomaly Agents

Room 2 has plenty of buffs that Anomaly Agents can take advantage of, including increases to both Anomaly Proficiency and Attribute Anomaly DMG. While having any two Anomaly Agents of different Attributes can be effective for triggering Disorder, pairing Yanagi with Burnice in this room would work extremely well due to enemy weaknesses.

How to Beat Room 3

Bring Rupture Agents

Rupture Agent for Room 3
The Sheer DMG buff in Room 3 makes it the ideal stage to bring your Rupture Agents. Yixuan is the best choice to take advantage of enemy weaknesses, but other Rupture characters like Yidhari can also be effective due to the room buffs.
