General Tips

Most chambers don't have any strict element requirements. As usual, it's best to try to build teams for each chamber one at a time when going for stars.

characters in particular are better on Side 1 for Chamber 1, but Side 2 for Chamber 2. You will often want to change setups for each chamber.

Chamber 1

Monster Level - 90

	Side 1	Side 2
Shieldbreakers
Preferred DPS Elements
Avoid DPS Elements

Side 1

In Depth Guide	Other Info
Nobushi	227K HP
Pyro Agent	347K HP

Make sure to bring Crowd Control on this side to stagger the mobs. The Pyro Agents can quickly combo you charactersout if left alone. characters that can pick up enemies are particularly effective here.

Try to save some burst damage for when the Pyro Agents spawn. If you can hit them with enough damage early, it will stagger them and break them out of invisibility, making them much easier to deal with.

Side 2

In Depth Guide	Other Info
Geovishap	555K HP
Hydro Mimic (Boar)	111K HP
Hydro Mimic (Ferret)	97K HP

In the first wave, aim for the Boars first, and let the Geovishap come to you. Boars tend to stay at range, and will heal over time.

In the second wave, aim for the Geovishap first. Ferrets will naturally group up and will usually go down to AoE damage.

DPS works the best here, as it is effective against all the enemies. Build a team around that if possible.

The mimics should go down fairly easily to AoE damage, however if you're struggling with them then bring to Freeze them.

Geovishaps will Infuse once they reach 50% HP, adding Elemental attacks which make the particularly annoying with the Hydro Mimics. Try to kill the Mimics before Geovishaps infuse.

Chamber 2

Monster Level - 92

	Side 1	Side 2
Shieldbreakers
Preferred DPS Elements
Avoid DPS Elements

Side 1

In Depth Guide	Other Info
Maguu Kenki	1.5M HP

This is a difficult fight if you're not familiar with the attacks and dodge timings. Check the in depth guide page and practice on the overworld version a few times to get used to it's attacks.

Remember once the Maguu Kenki reaches 75% HP it will become invulnerable and perform an AoE attack. Make sure not to waste your damage on it during this time.

This is mostly a DPS check, so bring your most invested composition on this side when going for 3★.

Characters with strong single target damage (e.g. Hu Tao or Yoimiya) are highly recommended.

Side 2

In Depth Guide	Other Info
Cryo Cicin Mage > Ice Cage	383K HP
Mirror Maiden > Mist Bubble	772K HP

Make sure to bring Crowd Control on this side to stagger the mobs.characters that can pick up enemies are particularly effective here.

When going for stars, focus the Fatui Mages first, as they have the most HP and have Auras. Try to kill the Hoarders using AoE damage.

If you find yourself dying, you may want to focus the Hoarders first, as they are set up to trigger Elemental Reactions on you along with the Mages. Watch out for Freeze in particular in the first wave. Doing this may lose you time, but make the fight easier to deal with.

Chamber 3

Monster Level - 100

	Side 1	Side 2
Preferred DPS Element
Avoid DPS Elements

Side 1

In Depth Guide	Other Info
Ruin Hunter	551K HP
Ruin Destroyer	416K HP
Ruin Guard > Rumbling Stone	643K HP > 3349 DMG / Wave
Ruin Cruiser	416K HP

Try to make sure enemies are grouped and you're hitting at least 2 targets at the same time. Only hitting one enemy at a time makes this a much harder DPS check for 3★.

For each wave, attack the small Ruin Machines first and let the large one come to you.

The Rumbling Stone Aura deals a significant amount of damage, so having Shields or strong healers are recommended.

Grouping Guide

On the First Wave, move towards one of the Ruin Destroyers first, and see if the other one tunnels towards you. If it does not, you should simply reset the chamber and try again. Whether or not the other one tunnels and groups makes a huge difference in clear time.

On the Second Wave, run behind one of the Ruin Cruisers, and make sure you line up the other one directly behind the one you're facing, and start attacking. This should trigger the Orb Dash ability, sending the Ruin Cruiser backwards and hopefully into the other one. Follow it, and start attacking.

Side 2

In Depth Guide	Other Info
Ruin Guard	643K HP
Ruin Cruiser	416K HP
Ruin Grader > Rumbling Stone	827K HP > 3349 DMG / Wave
Ruin Defender	582K HP

Try to make sure enemies are grouped and you're hitting at least 2 targets at the same time. Only hitting one enemy at a time makes this a much harder DPS check for 3★.

The Rumbling Stone Aura deals a significant amount of damage, so having Shields or strong healers are recommended.

Grouping Guide

On the First Wave, run behind one of the Ruin Cruisers and make sure you line up the other one directly behind the one you're facing, and start attacking. This should trigger the Orb Dash ability, sending the Ruin Cruiser backwards towards the center.

The enemies here are more spread out than in the first side, so in order to fully group you will have to repeat this for the other Ruin Cruiser and also send it to the middle with the first one.

On the Second Wave, rush for the Ruin Grader first. This prevents it from using it's Charge attack which loses you time and splits up the enemies. The Ruin Defenders will usually group up on you by themselves, but be aware of their shields blocking damage.
