Keep in touch with this post because I will add more character comp and some tips in future
Floor 11 guide: https://www.tacter.com/genshin/guides/genshin-impact-spiral-abyss-floor-11-guide-tier-list-best-team-4e0512ee

Matrix Algorithm/ Primal Construct

Electro is the best way to counter them, even better if there are more Dendro Characters. Every time they turn invisible, apply Electro to stun them.
Black Serpent Knight: Windcutter

If one of the Black Serpent Knight: Windcutter's attacks is fully absorbed by a player's Shield (does not count if the shield breaks as a result of the attack), it will gain a temporary buff at the cost of 15% of its Current HP, which increases its ATK by 30% and allows it to blink away from the next attack and take no DMG no matter the scale.
Rifthound

Rifthounds apply corrosion status on hit, which continuously drains HP from all party members. Shield cannot protect you from this status. So Healers are the best choice for protection.
First Half
- Require the ability to deal good single-target damage and AOE damage.
- Electro characters are highly appreciated because of their ability to counter Matrix Algorithm and Primal Construct.
Recommended team












For F2P











Artifact: 2pc HP% + 2pc HP%
Second Half
- Requires high AOE damage
- Should have Hydro characters in the team to break the Pyro shield
- Healers are the best choice for protection because Rifthounds and Black Serpents counter Shielders
- Pyro DPS is not rated highly because of the enemy's high resistance to Pyro
Recommended team












For F2P
