Shorekeeper Build Guide

What to know before spending pulls

Her base kit already contains healing, the full Crit support field, team damage amplification, and one fatal-hit rescue every 10 minutes. Build toward 250% effective Energy Regen first because both Stellarealm Crit bonuses reach their caps there. Her inherent skill grants 10% Energy Regen while the active character stands inside a Stellarealm, so the out-of-combat sheet can be 10 points lower if that condition remains active during the field.

Do you need the signature weapon?

Stellar Symphony is Shorekeeper's featured weapon. At level 90 it has 413 ATK and 77% Energy Regen. It grants 12% HP, restores 8 Concerto Energy after Liberation once every 20 seconds, and a healing Skill gives the team 14% ATK for 30 seconds. Variation is the accessible 4-star option listed by the build, with 338 ATK and 51.8% Energy Regen. Its Skill restores 8 Concerto Energy. Stellar Symphony supplies more Energy Regen, HP, and team ATK; Variation still supports the Skill and Outro rotation with a simpler resource effect.

Another character copy or the weapon?

S1 means Shorekeeper's first Resonance Chain upgrade. It expands Stellarealm's range by 150%, extends its duration by 10 seconds, and prevents Discernment from ending the field. Stellar Symphony instead supplies 77% Energy Regen, HP, Concerto Energy, and team ATK. S1 makes positioning and the final Intro more forgiving; the weapon makes the 250% Energy Regen target and each Outro easier to reach. Her healing, Crit fields, rescue, and team amplification work at S0.

Advice for your account

Easy rotation

On the first cycle, complete the four-hit Basic Attack string, then hold Normal Attack long enough to convert the gathered Deductive Data into Empirical Data. Repeat the normal string and held Heavy Attack as needed to build Concerto Energy. Cast Chaos Theory for a team heal, use the Echo, then cast Liberation to create Outer Stellarealm. Leave through Outro to the sub damage dealer. That character's Intro upgrades the field to Inner Stellarealm and adds Crit Rate. Build their Outro and send the main damage dealer in through a second Intro, upgrading the field to Supernal Stellarealm and adding Crit DMG.

Opening vs. repeat cycles

The first rotation is longer because Shorekeeper may enter without Intro and must build Empirical Data and Concerto through normal attacks. On later cycles, Intro heals, summons five Dim Star Butterflies, and shortens the setup. When Shorekeeper later enters a Supernal Stellarealm, Discernment replaces her first Intro, deals a guaranteed Critical Hit, heals the team, and ends the current Stellarealm at S0.

Why this skill priority

Liberation and Resonance Skill lead because End Loop contains every Stellarealm stage and Chaos Theory provides immediate team healing. Forte, Basic Attack, and Intro follow because they build the butterflies, Empirical Data, and Concerto route that gets Shorekeeper back to Outro.

Required buffs and assumptions

The full Crit package requires two teammate Intro Skills inside the same Stellarealm. Outer provides healing, the first Intro creates Inner and Crit Rate, and the second creates Supernal and Crit DMG. Characters must remain inside the field to receive its effects. Outro's interruption recovery lasts up to 30 seconds and can trigger at most five times.

Energy Regen target

Target 250% effective Energy Regen to cap both Stellarealm Crit bonuses. While the on-field character is inside a Stellarealm, Self Gravitation adds 10% Energy Regen to Shorekeeper, so a 240% sheet can reach 250% under that condition. Any additional Echo or team Energy Regen can reduce the sheet requirement further only while its own condition is active.
