Cyrene Notes & Intro

This section lays out the baseline for Cyrene’s Evernight DPS, including rotation concepts, waves, and the trade-offs in different eidolons. It also explains how signatures interact with other unit simulations and why some values appear counterintuitive in certain setups. The goal is to provide a robust reference for comparing investment scenarios across Eidolons and Light Cones. The discussion emphasizes that simulations are environment-specific and not universal absolutes, and that results can vary with wave resets, enemy resistances, and team composition.

Signature interactions & Rotations

Signature simulations scale off other simulations with her signature, and vice versa. In other words, if you want to see a specific investment's performance over E0S0, refer to the right column. Eidolon 4 This Love, Forever 123715.4 55,671,951 15.91% 15.91% 166662.9 74,998,294 34.71% 56.14%

E0S0 to E0S1 comparisons

This section illustrates how signatures and Eidolons influence damage across different enemy setups, emphasizing that rotations and wave management can drastically alter observed DPAV values.

Additional Observations

Eidolon data sometimes appears lower in some comparisons; this is often explained by the early Ult timing in Cyrene-led teams.
The impact of Sig interactions increases when combined with Evernight’s kit in specific formations.

E0S1 Sunday, E0S0 Tribbie, S1 Hyacine This is over 300 AV, similar to an AA Knight 0 Cycle. With this in mind, since they're different DPAV (and one has an extra

support), they must not be compared to the left. Enemies are also much more aggressive here. Anyway, It's very hard for Mydei's allies to die in his sustainless teams; I reccomend running these over sustained if he's fairly invested and the enemy isn't Pollux or something

*Hyacine is S1, a bit unfair. The 18% Vuln (+ Hya DMG) is the only reason they're not equal. i dont recc her here for mydei alone

Level 95 Normal Elite; 0% ALL-Type RES 120 Toughness; 132 SPD

Something I noticed is his ULT's frequency drastically decreases in a Cyrene team; Sunday's has double over 450 AV. The difference is that in Cyrene teams, you're able to GBG significantly more. Check each sheet to find how frequent Mydei

(GBG, ULT) acts near the bottom (every sheet L70:M77)

I hope you all like this format! instead of linking it here,

I've chose to sort it by section. You can find the

character-specific page there instead. Here is every unit I plan to calc for characters following the path of Nihility:

→ Hysilens

im gonna keep a real tight eye on these because it feels like Cery/RMC/Cat are being underrepresented somehow... but if they are other than the disclaimer i mentioned, I can't find where.

E0S0 Cyrene, E0S0 Kafka This isn't exactly enough to make BS not the best option, though, cause Swan is around 40% of damage here. There are some runs where they clear at the same speed (I've played some as well) albeit the 3rd Heirs would be a bit behind. Everything appears fine but I'll update immediately if I notice something anyways

DPAV should never be cross-referenced; it is only Gap thins (non-Kafka Cyrene and Triple DoT) by a lot when Hysilens is E1

relevant to THIS sheet in their individual tabs. Again, targets and cycles vary.

Cyrene Megasheet @camaraderia on discord

Cyrene Overview & Final Thoughts

This Megasheet aggregates and cross-references damage formulas, rotation patterns, wave resets, and Eidolon impact to equip players with detailed DPS expectations for Cyrene across Evernight, Castorice, and allied units. The content also explores how different light cone sets and relic sets influence overall output, while acknowledging the limitations and variability inherent in virtual simulations. The material is intended for advanced players who want to understand the DPS landscape for Chrysos Heirs teams and optimize rotation strategies.
