Team Recommendations

Important element in the first half: Pyro
Pyro is important here to destroy the weak point of Cryo Regivine in the last chamber. It is best to bring 2 Pyro characters. In addition, try to bring another element so you can create elemental reactions, preferably Electro for Overload.

Important element in the second half: Hydro
Hydro is important here to destroy the weak point of Pyro Regisvine in the last chamber. It is best if you bring 2 Hydro characters.

Floor 8 Chamber 1

Enemy Level	Challenge	Total Time
70	✩ – Finish before 3:00 ✩✩ – Finish before 5:50 ✩✩✩ – Finish before 7:00	10:00 minutes

First Half

*Slowing Water: Elemental Skill and Elemental Burst CD +100%.*

There is only one wave here and it’s Cryo Abyss Mage and Hydro Abyss Mage. The Hydro Mage has a Slowing Water Aura that will pulse every 15 seconds so focus on it first.
When you start the challenge, instead of approaching the Mages, go back to the back area and stay there so that the 2 Mages will teleport to your location. But don’t be too far back or the Mages won’t move, stay in the position like my Heizou above.
If you take too long to defeat the Hydro Abyss Mage, it has an attack that spawns a bubble that will catch after you. Use any ranged character (bow) to destroy the bubble from afar or use any Skills.

Second Half

*Tracking Fire Ball Ability: A fireball will trace the on-field character and deal Pyro DMG per 0.7 seconds to the character in range. The attack has 3 waves and the duration is 1.6 seconds per wave.*

There is only one wave here and it’s double Pyro Abyss Mage. The Pyro Mage on the left has a Tracking Fire Ball Ability that will be activated every 20 seconds so focus on that Mage first as that ability can drain a lot of Stamina if you’re trying to dodge it and deal a ton of damage if you didn’t avoid it.
Similar to the first half, when you start the challenge, instead of approaching the Mages, go back to the back area and stay there so that the 2 Mages will teleport to your location.
Once they’re both together like in the image above, spam your Hydro attacks to remove their Pyro shield fast.

Floor 8 Chamber 2

Enemy Level	Challenge	Total Time
70	✩ – Finish before 3:00 ✩✩ – Finish before 5:00 ✩✩✩ – Finish before 6:00	10:00 minutes

First Half

There is a Cryo Elemental Node in the middle that will provide 100% DEF to enemies near it every 15 seconds (can be seen by a Cryo sheen on them). It will also apply Cryo on enemies so you can take advantage of it and trigger elemental reaction damage, which will also remove the buffs they have.
When you start the challenge, focus on the Hilichurl Shooters so they can’t stagger you with their arrows.
Once all the Hilichurls are defeated and only the Ruin Guard is left, you can start attacking it (if it’s still alive). You can stun the Ruin Guard by hitting its eye or the core at the back of its head if you’re having trouble with it moving around. However, if you’re out of time, it’s better to brute force and dash to avoid incoming attacks.

Second Half

There is a Pyro Elemental Node in the middle that will provide 40% ATK to enemies near it every 15 seconds (can be seen by a Pyro sheen on them). It will also apply Pyro on enemies so you can take advantage of it and trigger elemental reaction damage, which will also remove the buffs they have.
When you start the challenge, focus on defeating all the Hilichurls as they spawn all over the arena (even better if you can gather all the available Hilichurls near the Ruin Guard with an Anemo CC).
Once all the Hilichurls are defeated and only the Ruin Guard is left, you can start attacking it (if it’s still alive). You can stun the Ruin Guard by hitting its eye or the core at the back of its head (using a Bow character’s Aimed Shot) if you’re having trouble with it moving around. However, if you’re out of time, it’s better to brute force and dash to avoid incoming attacks.

Floor 8 Chamber 3

Enemy Level	Challenge	Total Time
70	✩ – Finish before 1:00 ✩✩ – Finish before 2:00 ✩✩✩ – Finish before 3:00	10:00 minutes

First Half

The Regisvine will start with its weakness at its root. Use Pyro attacks to destroy the weakness fast and stun it for several seconds. When it’s stun, spam all your Elemental Burst to decrease its HP.
If the Regisvine is still not dead, it will recover and have its weakness on the Corolla at the top (you will receive a notice saying “the Corolla is forming…” when it occurs). In this phase, it will be hard for your non-bow characters to reach the weakness so you can only wait for the Regisvine to deal with certain moves like faceplant attack where it will smash the corolla to the ground so that even your melee characters can reach it.
