Chaos’ passive launches a massive hit when Remora duration ends, scaling up the longer Remora has lasted. This instantly makes
Hathor his best ally in any team because her passive extends Remora duration from 5 seconds to 12 seconds.
Skia, on the other hand, shortens Remora duration, so he kills this synergy.
The other component of Chaos kit requires Ultimate uptime, which prefers Charged teams.
Chaos Charged Team
Chaos,
Hathor,
Zero,
Jiuyuan
The natural fitting team for a main DPS Chaos, with Zero’s instant Esper Meter refill, and Hathor extending Remora duration to buff his passive, while also granting a Crit Rate buff. Jiuyuan groups enemies for Chaos, because his AOE is small, and works as burst DPS, with healing with her A2.
This team has the highest uptime of Chaos’ Ultimate, and relies on him staying on-field most of the time.
Stain Team
Chaos,
Hathor,
Zero,
Fadia
Chaos,
Hathor,
Zero,
Haniel
The comfort option for Chaos is using Fadia, given his charged attacks have a long animation and he’s open for enemy attack while casting. Fadia negates a lot of damage taken, and adds Stain reaction, which increases Lakshana damage taken by enemies.
Zero focuses on renewing Remora on cooldown, and Chaos swaps to Fadia for Stain, so both have decent uptime, but you lose the Ultimate energy regeneration from Charged. So there’s room to use Hathor’s full kit while his Ultimate is down.
Zero doesn’t benefit from building Cycle Intensity in this team, as Remora doesn’t deal much damage on itself.
Haniel is a more offensive option, but this version is the weakest in defenses. You lose Zero's small healing, Jiuyuan CC and potential healing, and Fadia's damage mitigation.
Chaos Hotori Blossom Team
Chaos,
Hotori,
Zero,
Jiuyuan
Using the infamous Zero + Hotori duo, this team exploits replicated skills to trigger more reactions. It’s similar to the Mono Blossom team, but for accounts without Nanally.
Once spawned, Blossom deals damage passively over time, and doesn’t require any specific character on-field. It also scales with Cycle Intensity on Zero, so it’s an excellent secondary DPS source.
Hotori plays as a third source of DPZ (Damage Per Zero-second as she stops the timer), and replicates skills to help build up both Esper Meter and Ultimate energy.
Remora duration will be shorter without Hathor, and Chaos’s nuke will deal significantly less damage. But we compensate with other sources.
