- Shorekeeper buffs scale primarily with Energy Regen and improve as Stellarealm evolves.
- Inner Stellarealm provides up to 12.5% Crit. Rate to allies inside the field.
- Supernal Stellarealm adds up to 25% Crit. DMG after a second Intro Skill.
- Two Intro Skills are required to fully upgrade the field before Shorekeeper detonates it.
- 250% Energy Regen is the recommended target for maximum Crit-based support.
Shorekeeper Buffs Overview
Shorekeeper buffs are built around her Resonance Liberation, which creates the Stellarealm field. The field begins as a healing zone, then evolves when allies use Intro Skills inside it. Once fully upgraded, it supports the team with Crit. Rate, Crit. DMG, damage amplification, healing, and recovery utility.
Her value is especially consistent for teams with damage dealers that benefit from Crit-based scaling. Because the field can support different attributes, Shorekeeper can slot into many compositions without requiring a specific elemental pairing.
Healing
The Outer Stellarealm restores HP periodically for nearby party members, giving the team steady off-field sustain.
Crit. Rate
The Inner Stellarealm grants up to 12.5% Crit. Rate based on Shorekeeper's Energy Regen.
Crit. DMG
The Supernal Stellarealm adds up to 25% Crit. DMG after a second Intro Skill activates inside the field.
Damage Utility
Shorekeeper also provides 15% damage amplification through Binary Butterfly and universal support through her Outro Skill.
Treat Shorekeeper as a setup support rather than a long-field damage dealer. Build her Liberation, trigger two Intro Skills, then return to the main DPS while Stellarealm remains active.
| Buff Source | Effect | Activation Requirement |
|---|---|---|
| Outer Stellarealm | Periodic healing | Cast Resonance Liberation |
| Inner Stellarealm | Up to 12.5% Crit. Rate | One Intro Skill inside Outer Stellarealm |
| Supernal Stellarealm | Up to 25% Crit. DMG | Two Intro Skills inside the field |
| Binary Butterfly | 15% damage amplification and interruption recovery | Shorekeeper's Outro-related effect |
| Life Entwined | Prevents one fatal blow for another Resonator | Inherent Skill active; long cooldown |

How to Maximize Stellarealm
The most important part of using Shorekeeper buffs is managing the order of your swaps. A Liberation alone creates only the Outer Stellarealm, which heals but does not provide the full Crit package. Your next two characters must enter with Intro Skills while standing inside the field.
The field lasts long enough to support a complete team rotation, but poor positioning can prevent an Intro Skill from upgrading it. Keep the active character close to Shorekeeper's Stellarealm before swapping.
Charge Shorekeeper's Liberation
Use Basic Attacks, her Resonance Skill, and Forte actions to build Concerto Energy and Resonance Energy. Her Liberation has a high energy cost, so Energy Regen should be prioritized during setup.
Cast the Outer Stellarealm
Activate Resonance Liberation when the team is ready to begin its damage cycle. The initial field heals allies but does not yet provide Crit. Rate or Crit. DMG.
Trigger the First Intro Skill
Swap to the next Resonator with a full Concerto Gauge. Their Intro Skill must occur inside the field to evolve it into the Inner Stellarealm and unlock Crit. Rate.
Trigger the Second Intro Skill
Complete the next character's rotation, then swap again with a full Concerto Gauge. The second Intro Skill upgrades the field to Supernal Stellarealm and unlocks Crit. DMG.
Detonate the Field
Return to Shorekeeper after the field reaches its final stage. Her enhanced Intro Skill, Discernment, ends the Stellarealm, restores HP, and deals guaranteed Critical Hit damage.
The Crit bonuses apply to characters inside the Stellarealm's effective range. Do not rush both swaps if the next Resonator will enter outside the field.
| Stellarealm Stage | Healing | Offensive Buffs | Upgrade Method |
|---|---|---|---|
| Outer | Periodic HP restoration | None | Cast Resonance Liberation |
| Inner | Retains Outer healing | Up to 12.5% Crit. Rate | One Intro Skill in the field |
| Supernal | Retains Inner effects | Up to 25% Crit. DMG | Second Intro Skill in the field |
A reliable rotation normally follows this pattern:
Shorekeeper Liberation → Sub-DPS Intro → Sub-DPS rotation → Main DPS Intro → Main DPS burst → Shorekeeper enhanced Intro.
Energy Regen and Build Priorities
Energy Regen is the defining stat for Shorekeeper buffs. Her Crit. Rate and Crit. DMG bonuses use Energy Regen scaling, while her healing improves through HP. This creates a clear split in priorities: reach the Energy Regen target first, then add HP and healing-focused stats.
The recommended maximum target is 250% Energy Regen. Shorekeeper's inherent skill can provide an additional 10% Energy Regen while another Resonator is within Stellarealm, and Fallacy of No Return can provide another useful Energy Regen contribution.
Best General Build
Use 5-piece Rejuvenating Glow with Fallacy of No Return as the main Echo. This balances healing, Energy Regen, and team utility.
Signature Weapon
Stellar Symphony provides HP and a large Energy Regen bonus, making the 250% target easier to reach.
Accessible Alternative
Variation offers Energy Regen and helps restore Concerto Energy after using Resonance Skill.
If Shorekeeper cannot approach the Energy Regen target, prioritize ER main stats and substats before adding extra HP. A stronger field rotation usually provides more team value than modestly larger heals.
| Build Slot | Recommended Priority | Reason |
|---|---|---|
| 4-Cost Echo | Healing Bonus or Crit. DMG | Healing Bonus improves sustain; Crit. DMG supports her field detonation |
| 3-Cost Echo | Energy Regen or HP% | Energy Regen supports Stellarealm buffs; HP improves healing |
| 1-Cost Echo | HP% | Shorekeeper's healing scales with HP |
| Substats | Energy Regen, HP%, Crit. DMG, Resonance Skill DMG | Energy Regen first, then sustain and personal damage |
| Sonata Effect | 5-piece Rejuvenating Glow | Strengthens Shorekeeper's healing-focused support role |
| Weapon | Main Benefit | Use Case | Rating |
|---|---|---|---|
| Stellar Symphony | HP and high Energy Regen | Best premium option for reaching the ER target | ★★★★★ |
| Variation | Energy Regen and Concerto recovery | Strong accessible alternative | ★★★★☆ |
| Call of the Abyss | Energy Regen and Healing Bonus | Practical free-to-play option | ★★★★☆ |
| Other HP Rectifiers | HP-focused support | Use when Energy Regen requirements are already covered | ★★★☆☆ |
Skill upgrades should focus on Resonance Liberation and Intro Skill first. Liberation improves the healing attached to Stellarealm, while Intro Skill improves the damage of Discernment. Resonance Skill follows because it contributes healing and Concerto Energy. Forte Circuit and Normal Attack can be upgraded afterward.
Rotation Tips for Shorekeeper Teams
Shorekeeper's combat loop is short and deliberate. Her Basic Attacks generate the resources needed for Flare Star Butterflies, while her Resonance Skill provides direct healing and Dim Star Butterflies. Once her gauges are ready, the team should transition quickly into the Stellarealm sequence.
Avoid spending too much time on Shorekeeper after her Liberation is available. Her strongest contribution comes from enabling allies to use the field's buffs, not from extending her own on-field combo.
Always check the previous Resonator's Concerto Gauge before switching. Shorekeeper's enhanced Intro Skill and Stellarealm upgrades depend on properly timed Intro Skills.
| Rotation Phase | Shorekeeper Action | Team Objective |
|---|---|---|
| Opening | Basic Attacks and Resonance Skill | Generate Forte, Concerto, and healing |
| Setup | Cast Resonance Liberation | Create the Outer Stellarealm |
| First Swap | Switch with full Concerto Energy | Trigger the Inner Stellarealm |
| Second Swap | Switch after the next rotation | Trigger the Supernal Stellarealm |
| Burst Window | Main DPS uses major skills | Capitalize on Crit. Rate and Crit. DMG |
| Reset | Return to Shorekeeper | Detonate the field and begin the next cycle |
Use the following compact combo when you need a fast setup:
Basic Attack chain → Enhanced Heavy Attack → Resonance Skill → Resonance Liberation → swap with full Concerto Energy.
The Enhanced Heavy Attack consumes Shorekeeper's Forte Gauge, pulls enemies together, and causes existing Collapsed Cores to transform into Flare Star Butterflies. Her Unbound Form can help reposition while generating data, which is useful when enemies move outside the intended field area.
Before Your Main DPS Burst:
- Shorekeeper has enough Energy to cast Resonance Liberation
- The Outer Stellarealm covers the active swap area
- The first Intro Skill upgrades the field to Inner Stellarealm
- The second Intro Skill upgrades the field to Supernal Stellarealm
- The main DPS remains inside the field during the burst
Best Team Roles and FAQ
Shorekeeper buffs are flexible because they provide healing, Crit support, and all-type damage utility rather than depending on one specific damage attribute. She can support premium teams with high burst windows or more accessible teams built around Rover and other available Resonators.
For a standard composition, use Shorekeeper as the sustain and buffer, a sub-DPS to trigger the first field upgrade, and a main DPS to receive the completed Stellarealm buffs.
| Team Position | Recommended Function | Rotation Responsibility |
|---|---|---|
| Shorekeeper | Sustain and universal support | Create, upgrade, and detonate Stellarealm |
| Sub-DPS | Off-field damage and first swap | Trigger the first Intro Skill and contribute damage |
| Main DPS | Primary field damage | Enter after the second Intro Skill and use burst abilities |
Premium Burst Team
Pair Shorekeeper with a strong main DPS and sub-DPS that can quickly fill Concerto Energy. This setup maximizes the value of her Crit buffs.
Rover Team
Rover receives additional Energy Regen from Shorekeeper's inherent skill when included in the party, improving Liberation access.
Flexible Attribute Team
Shorekeeper's support effects can benefit DPS characters of different attributes, making her a dependable general-purpose healer.
Choose allies that can consistently perform Intro Skills and complete rotations inside Stellarealm. Smooth field timing is more important than forcing a narrowly themed lineup.
Q: What are Shorekeeper buffs based on?
Her main Crit. Rate and Crit. DMG buffs are based on Shorekeeper's Energy Regen and are delivered through the upgraded Stellarealm created by Resonance Liberation.
Q: How many Intro Skills are needed for maximum Shorekeeper buffs?
Two Intro Skills must be activated inside the field. The first creates Inner Stellarealm and unlocks Crit. Rate, while the second creates Supernal Stellarealm and unlocks Crit. DMG.
