How to Beat Room 1

Group Enemies Together

This strategy applies to the first and second waves. Group the Miasmic normal enemies together, then easily defeat them with one skill. You can gather the enemies by running around them and positioning your agent before unleashing the skill.

Rely on Dodges and Parries

The best way to deal with the Lockspring is by using Defensive Assists, as this enemy has fast attack combos. Pay attention to its attack patterns and quickly switch between dodging and using defensive assists.

How to Beat Room 2

Lessen HP Before Miasmic Field

You should reduce the Covenant Guardian's HP as much as possible before it enters its Miasmic Field. If you're using a Rupture team, you can continue your standard strategy during the Miasmic Field phase to purify it.

However, if you're using an Anomaly or Attack team, focusing on offense and removing the extra barrier will work too.

How to Beat Room 3

Perform Counters

Both the Farbauti and Dullahan have predictable attack patterns that can be easily countered. By paying attention to their attack cues, you can execute counterattacks.

Break Miasmic Shield

When facing the Miasmic Rampant Brute, avoid its attacks and concentrate on your offensive strategy to break its shield. Once the shield is down, it will be easier to defeat this enemy.
