My name is Anaxagoras, one of the Seven Sages of the Grove of Epiphany, founder of the Nousporists. Now, don't make me repeat the following again. Rule number one: Do not call me Anaxa. Rule number two: Never interrupt me — silence is golden. Remember that.

Each time Anaxa lands 1 hit on enemy targets, inflicts 1 Weakness of a random Type to the targets, lasting for 3 turn(s), with priority to the Weakness Type that the target doesn't already possess.
While Anaxa is on the field, inflicts the "Qualitative Disclosure" state on enemy targets that have at least 5 different Types of Weaknesses. Anaxa deals 30% increased DMG to targets afflicted with the "Qualitative Disclosure" state. In addition, after using Basic ATK or Skill on them, unleashes 1 additional instance of Skill on the targets. This additional Skill does not consume any Skill Points and cannot trigger this effect again. If the target has been defeated before the additional Skill is used, it will be cast on one random enemy instead.

Technique | Prism of the Pupil
[Impair]
After using Technique, inflicts the Terrified state on enemies in a set area. Terrified enemies will flee in a direction away from Anaxa for 10 second(s).

⟢ Why play Anaxa with The Herta?

Anaxa is the newest addition to the Erudition roster, and the first thing we need to check for is synergy with our beloved Erudition Emanator, The Herta! She gets stronger with a second Erudition partner, and currently we lack a “BiS” option for her—as Jade is only really strong in AoE (even Serval outperforms Jade in Single-Target with The Herta!)

✘ = You do not own the character

✔ = You do own the character

Scenario 1 ―

✘ Jade

✘ Tribbie / Robin / Sunday

✘ Aven / Lingsha / Huohuo

Anaxa's pull value here depends on whether Remembrance MC and Gallagher are available for your team.
- If RMC and Gallagher are available, Anaxa becomes your best pull.
- If they are unavailable, Tribbie becomes your best pull. It should be noted that if you are only using The Herta in AoE situations, Tribbie may be a better pull regardless of RMC's availability.
- If you have Luocha or Fu Xuan, use them and pull for Anaxa. If not, Aventurine, Lingsha, or Huohuo might have better value for your account over Anaxa.

Scenario 2 ―

✘ Jade

✘ Tribbie / Robin / Sunday

✔ Aven / Lingsha / Huohuo

If all you have is a premium sustain and...
- RMC is readily available, go get yourself an Anaxa.
- RMC is not available, please get Tribbie.

Scenario 3 ―

✘ or ✔ Jade

✔ Tribbie / Robin / Sunday

✔ Aven / Lingsha / Huohuo

- Get Anaxa! He’s the only upgrade left besides Eidolons.

Scenario 4 ―

✔ Jade

✘ Tribbie / Robin / Sunday

✘ or ✔ Aven / Lingsha / Huohuo

- Get Tribbie, even if you're stuck using Luocha or Fu Xuan. Tribbie is a flexible Harmony for other units, and the upgrade from RMC to Tribbie is a higher DPS increase than Jade to Anaxa. Tribbie also has amazing synergy with Jade, as sometimes you’d rather put Debt Collector on Tribbie for max stacks.

Scenario 5 ―

✘ or ✔ Jade

✔ Tribbie / Robin / Sunday

✘ Aven / Lingsha / Huohuo

- It depends on which sustains you have available aside from Gallagher. If your Gallagher is free, by all means get Anaxa. If you have Luocha or Fu Xuan, Anaxa is still recommended. If you are stuck using Bailu or Gepard… please pull for another sustain.

ATK% or Wind DMG% Orb?

ATK% is your go to, as Anaxa has a lot of DMG% sources in most teams (Skill Passive, Minor Traces, Erudition Buff from Trace, LCs). The difference isn’t too big though, so go with substats most of the time.ATK%:
⟢ 8% increase to personal DPAV
⟢ 2% increase to team DPAV

TL;DR - ERR is better without hit energy, ATK is better with. Most scenarios in the game do contain hit energy however, therefore ATK is the most consistent.ERR:
⟢ 2.8% decrease in Team DPAV
⟢ 23% decrease in Personal DPAV
Greatly fluctuates in scenarios with no hit energy.

Passkey
✦✦✦
After the wearer uses their Skill, additionally regenerates 8 / 9 / 10 / 11 / 12 Energy. This effect cannot be repeatedly triggered in a single turn.

Tribbie
Tribbie’s synergy with The Herta already popped off without Anaxa, but his Sub-DPS playstyle allows Tribbie’s teamwide buffs to shine brighter compared to more battery-type Erudition partners.

Remembrance Trailblazer
While RMC typically does not give Anaxa “Mem Support”, her CDMG buff still applies to him. Both Anaxa and RMC have very flexible SP usage, essentially supporting each other indirectly.

Robin
Robin’s teamwide DMG, Action Advance, and ATK buffs are all usable by Anaxa to 100% extent. Anaxa typically lacks ATK buffs and prefers SPD boots, making ATK buffers like Robin highly valuable.

Sunday
Sunday and Anaxa typically have no direct synergy in The Herta teams, as Sunday should buff The Herta over him. However, Sunday’s value for The Herta is still extremely high, creating a solid team even with a lack of buffs on Anaxa himself.

Ruan Mei
Ruan Mei’s combination of teamwide buffs brings very good Personal-DPR for Anaxa. That combined with the Weakness Implant + Break Efficiency creates great synergy amongst the two, even if Ruan Mei does not buff The Herta as much as other units. And SHE'S FREE!

Pela
Pela’s DEF Shred synergizes well with Anaxa’s innate DEF Shred, alongside other shred sources such as S1 and Genius if available.

Lingsha
Lingsha’s Break-Based abilities, AoE DMG, and High Attack Frequency capitalizes on both The Herta’s energy/stacking mechanics, and Anaxa’s Weakness Implant. Her only weakness being a bit of SP Defficiency if wanting to play optimally.

Gallagher
The undisputed goat of sustain, everything that makes Gallagher great applies to Anaxa and The Herta. SP Efficiency, Break DMG, High Break Efficiency, and Self AA makes an AMAZING 4* unit.

Aventurine
Aventurine’s SP Efficiency, High Attack Frequency, CDMG and Effect RES buffs are all amazing all-rounder buffs, great for any DMG dealer. Playing with Tribbie (which you should be if possible) also gives Aventurine more stacks through Follow-Up Attacks.

Huohuo
Huohuo to this day still has the best buffs that any sustain can offer, giving Teamwide Energy, ATK, and Auto Cleanse. However, her SP Neutrality/Defficiency can cause a few problems when playing with The Herta and Anaxa, and her healing is not to the level of other sustains. She also lacks the Attack Frequency of other sustains.

Fu Xuan
FX’s Teamwide 10% CR Buff and Debuff Resist are all very valuable in Dual-DPS teams, however her uptime requires very careful SP usage.

Luocha
Still arguably the best Abundance unit in terms of pure-healing through his Field and Insta-Heal. Sadly, that is all he provides besides SP Efficiency, making him more of a slap-on sustain, rather than one with specific synergies.
