A complete look at Coppelia’s Conduit kit, The Silent Anthem psychube, Insight upgrades, and the teammates who use her Energy.

Coppelia is a 6-star Mineral character in Reverse 1999 who deals Reality damage and fills a Support and Sub-DPS role. She arrived with the version 3.7 update and can be claimed for free as a third anniversary reward, so most players will own her at Portrait 0 without spending pulls. Her value comes from a different system than most Arcanists, built around Energy, Conduits, and heavy Critical buffs for the whole team.

Quick answer: Take Insight III, focus Critical DMG on her Resonance, equip The Silent Anthem, and pair her with an Energy-hungry Reality DPS such as The Twins or Regulus. Insight III is the key breakpoint because it grants the whole team 40% Conduit Might on entering battle.

How Coppelia’s Conduit system works

Coppelia does not use standard basic incantations or a normal Ultimate. Instead, her Inheritance effect, Auditory Memory, has her power a Conduit with Energy, and the Conduit repeatedly casts incantations at the end of the AP area by consuming that Energy. Her Moxie resource is also replaced by Harmonization, and she gains 15 Harmonization at the start of every round.

Because of this, her damage and support scale with how much Energy your team spends. The more Energy allied Conduits burn through in a round, the stronger her attacks and stacks become. This is why she belongs in teams that naturally consume large amounts of Energy rather than in ordinary Moxie-based lineups.


Coppelia skills breakdown

SkillTypeEffect
Tuning TechniqueIncantationSingle-target attack for 480% Reality DMG, plus 120% Reality DMG per level of Energy consumed by allied Conduits that round (up to 20 levels).
Clarity in ClefsIncantationGrants Symphonic Unity to all allies for three rounds, boosting Critical Rate by 40% and Critical DMG by up to 48% based on Coppelia’s stat.
Song Etched Into Her FormUltimateAoE attack for 960% Reality DMG, plus 64% Reality DMG to the main target per Chromatic Progression stack.

Tuning Technique is her main damage tool, and it is weak early in a round and strong late. Let your Energy users spend first so the Energy Consumption counter climbs, then fire it for the extra 120% per level. Clarity in Clefs is the reason to invest in her Critical DMG, since the buff it hands the team scales off her own Critical DMG value.

Song Etched Into Her Form is her burst window. After it attacks, it consumes all Chromatic Progression stacks, raises Energy Accumulation by four levels for the round, and grants three stacks of Conduit Calibration I to the team. Because Conduit Calibration lowers Energy cost, this creates a cheaper follow-up window that pairs neatly with a big Tuning Technique.

Best Psychube: The Silent Anthem

The Silent Anthem is Coppelia’s 6-star signature Psychube and the most natural choice for her. On entering combat she gains an 8% DMG buff thanks to her Mineral Afflatus. Then, for each Conduit Energy consumed by allies, it grants 0.6% Conduit Might to the whole team for three rounds, stacking up to 16 times. That reward directly follows the Energy your team spends, which is exactly what her kit is built around.

If you do not have it yet, a Critical-focused Psychube works as a temporary stand-in until you can slot the signature option.

Insight effects and materials

Coppelia’s Inheritance effect, Auditory Memory, is what removes her basic incantations and Ultimate in favor of the Conduit and Harmonization mechanics. Each Insight level adds a passive that pushes her toward strong Critical support, with Insight III delivering the largest single upgrade.

Note: Because both her personal damage and the buff from Clarity in Clefs scale with her Critical DMG, prioritize Critical DMG on her Resonance grid before other offensive stats.


Best teammates for Coppelia

Coppelia rewards teams that spend heavy Energy, so her partners should either burn Energy or benefit from her Critical and Conduit buffs. A reliable core pairs her with a main DPS, a compatible support, and a sustain unit.

The Twins are another standout partner. Their Mineral attacks scale with Energy consumed and their burst grows stronger at higher Energy thresholds, so Coppelia’s Energy generation helps them reach those breakpoints faster. The key rule is to fill the team with Arcanists who actually use Energy, otherwise her Conduit support loses most of its value.

For most accounts, the practical build is Insight III, a Critical DMG Resonance setup, and The Silent Anthem, dropped into a Conduit team led by an Energy-hungry DPS. Since she is free at Portrait 0, you can start using her immediately and reserve Portrait upgrades for players who plan to run Conduit as a long-term team.
