Everecho is a 6-star Mineral Arcanist in Reverse: 1999 who deals Reality DMG and fills the Survival / Support role. Unlike a conventional healer who spends AP repeatedly casting recovery cards, Everecho is designed around the Conduit system. She converts team Energy activity into healing, survivability, and damage support while also providing useful defensive debuffs against enemies.

This Everecho build guide covers the best Everecho builds, her core mechanics, Resonance priorities, Psychubes, team options, Portrait value, gameplay, and pull advice.

Building another 6-star Arcanist can consume plenty of farming resources, especially when you are raising several accounts or preparing an entire Conduit team. OSLink can help with multi-instance account management and AFK progression, allowing you to keep different accounts running and handle routine resource farming more efficiently. That can make collecting Insight, Resonance, and Psychube materials for Everecho and her teammates less repetitive.

Everecho Role and Core Mechanics

Everecho is primarily a Conduit sustain rather than a universal healer. Her strongest teams continuously generate and consume Chaotic Energy, allowing her own mechanics to progress without requiring excessive AP.

One of her most important mechanics is Past Shadows, which provides team damage support. She can also apply Hollow Shell, reducing enemy Reality DEF, Mental DEF, and Critical DEF.

Her healing and support also scale with her own ATK, which is why building Everecho differs from building sustain characters that simply stack as much HP as possible.

Everecho Arcane Skill and Abilities

The Everecho arcane skill system is closely tied to Conduit mechanics and Harmonization rather than a standard Ultimate-focused rotation.

Tomorrow's Hope is her main emergency sustain tool. It heals the party based on Everecho's ATK while cleansing Stats Down, Neg Status, and Control effects.

Echoes' Embrace is particularly valuable offensively. It deals Mass Reality DMG and applies Hollow Shell, lowering multiple defensive stats while adding Past Shadows to allies.

This combination is what makes Everecho more than a healer: she keeps the team alive while actively improving its damage output.

Everecho Best Builds and Resonance

Everecho resonance should prioritize ATK first, followed by defensive stats.

ATK improves her healing and contributes to the effectiveness of her support mechanics, so an ATK-oriented Resonance setup generally gives better overall value than going all-in on HP.

You still want enough HP and DEF to keep her comfortable in difficult encounters, but the best Everecho builds should not sacrifice too much ATK purely for survivability.

Best Everecho Psychubes

The best Everecho Psychubes are those that reinforce her two main jobs: keeping the team alive and strengthening Conduit damage.

Her Version 3.8 signature Psychube is the natural first choice because its effects directly complement her healing and Conduit-oriented support.

If you intend to use Everecho long-term in a complete Conduit team, investing in her signature option provides the cleanest synergy. For more casual investment, a strong survival-oriented Psychube remains perfectly usable.

Best Everecho Team

The Everecho team section is where her specialization becomes most obvious. She performs best when surrounded by Conduit characters capable of generating and spending Energy frequently.

A strong core setup is:

This team creates a natural Conduit loop. The other members continually interact with Energy mechanics while Everecho supplies healing, defensive support, Past Shadows, and enemy debuffs.

She can technically be used outside Conduit teams, but doing so removes much of the reason to build her. Without frequent Energy consumption, Everecho may need to spend more AP actively healing instead of letting her passive systems handle much of the sustain.

Everecho Gameplay Tips

Good Everecho gameplay is surprisingly low-maintenance once the full team begins functioning.

The basic flow is:

Generate Energy → consume Energy → build Everecho's resources → trigger sustain/support effects → continue the Conduit rotation.

Most of the time, you do not want to constantly spend AP on Everecho. Let your Conduit characters drive the rotation and use Tomorrow's Hope when the team actually needs immediate healing or cleansing.

Her offensive support should also be timed around major damage windows. Applying Hollow Shell and stacking Past Shadows before your DPS performs its strongest sequence can noticeably improve total team damage.

Everecho Portrait Value

Everecho portrait upgrades strengthen an already complete P0 kit rather than fixing a missing mechanic.

P0 is enough for normal use. P1 is the most comfortable early upgrade if you want to invest further, while P2 becomes more attractive to players heavily committed to maximizing a Conduit team.

There is no need to chase high Portrait levels simply to make Everecho functional.

Pull Advice: Should You Pull Everecho?

The pull advice depends heavily on your roster.

If you already own The Twins, Coppélia, or other important Conduit units and want to continue developing that archetype, Everecho fills an important role by adding dedicated sustain without giving up offensive support.

If you do not play Conduit and mainly want a universally flexible healer, her priority becomes lower. Much of her kit gains value specifically from Energy generation and consumption, so other teams cannot take full advantage of what makes her special.

Overall, Everecho is a strong specialized sustain for players committed to Conduit gameplay. Prioritize ATK in her Resonance, use her signature Psychube when possible, and let Energy-focused teammates drive her support loop. Since building Everecho alongside an entire Conduit roster can require substantial resources, OSLink can also help with multi-account management and AFK farming, keeping routine resource collection moving while reducing the time spent repeatedly switching accounts and clearing the same farming stages.
