The ShorekeeperBuild and Guide

The Shorekeeper is a 5-star Spectro Rectifier wielder specializing in healing and supporting her allies. She shares a similar role to Verina and can similarly fit in almost any team composition. Her unique aspect is her buffs being CRIT-based instead of Attack%, which usually allows her to outperform Verina in the raw damage multiplication department (excluding other synergies). However, unlike Verina, she must follow a strict rotation as her buffing capabilities are entirely tied to her Resonance Liberation and Outro. This isn’t a bad thing, but understanding how to achieve it efficiently and consistently is very important if you want to use The Shorekeeper to her full potential.

Now let's dive into her kit.

Her Resonance Liberation: End Loop has an activation cost of whopping 175 Energy. Upon its use, she summons the Stellarealm for 30 seconds - a massive ring providing benefits to allies within its radius and generating Shorekeeper 20 Concerto Energy upon activation. Stellarealm features 3 different stages with each offering a benefit that can stack with each other. The initial summon will be in “Outer Stellarealm” variant, but whenever an ally executes an Intro skill within its bounds, it is upgraded to the next stage. The 3 stages are:

• Outer Stellarealm (Baseline) - Continuously Heal all allies once every 3 seconds.

• Inner Stellarealm (After 1 Intro) - Increases 0.01% Critical Rate per 0.2% of Shorekeeper’s Energy Regeneration up to 12.5% for all allies.

• Supernal Stellarealm (After 2 Intro) - Increases 0.02% Critical Damage per 0.1% of Shorekeeper’s Energy Regeneration up to 25% for all allies.

After using 2 Intros, your party gains Continuous Healing, 12.5% Critical Rate and 25% Critical Damage for the duration of Stellarealm. To achieve this though, you’ll need to ensure The Shorekeeper is built with enough Energy Regeneration - the magic number being 250% (150% from Echoes, Weapon, and Passives). Additionally, the 250% Energy Regeneration is a comfortable checkpoint to ensure her timely access to her Ultimate in most team set-ups as well. As her Resonance Liberation features a 25-second cooldown, with careful planning you should have no trouble maintaining its uptime for most of the fight.

Her other key supportive ability is her Outro, which grants the entire party a 15% Damage Amplification buff for 30 seconds, regardless of how many times they Swap In-or-Out. As an added bonus, whenever the On-Field Resonator is launched/knocked back, you can immediately recover and execute Perfect Dodge followed by a Dodge Counter by tapping the Dodge button. However, this effect is limited to 5 times per application.

These two abilities form the core of her kit and are the focus of everything she will aim to achieve on the field. The game plan is simple:

• generate as much as Concerto Energy as fast as possible,

• summon the Stellarealm and then immediately perform her Outro triggering another character's Intro to upgrade the realm immediately and apply Shorekeeper’s Outro buff,

• after which you only require 1 more Intro to fully upgrade the realm.

Fortunately, the rest of her kit is competent at generating Concerto quickly, so let's take a look at that. Her Forte Circuit: Astral Chord is divided into two different charge-based resources - “Collapsed Cores” and “Empirical Data”.

“Collapsed Cores” are glowing orbs that materialize on the field when triggered and are generated by the use of any of her standard Basic Attacks. These Cores transform into “Flare Star Butterflies” after 6 seconds of spawn - a homing missile attack targeting the closest enemy dealing small damage but generating good Concerto Energy. She can only have 5 Cores active at once, with additional Cores transforming the oldest Core into a Butterfly ignoring the 6-second rule.

“Empirical Data” also features a 5 charge limit and is generated via her Basic Attacks, but can be only used once you have accumulated all 5, enhancing her next Heavy Attack of Mid-Air Attack, consuming all charges and gaining the following effects:

• Enhanced Mid-Air Attack: Forte Transmutation - Deals Spectro damage, generates good Concerto Energy, and converts all “Collapsed Cores” into “Flare Star Butterflies” instantly and can be followed up by Basic Attack 2.

• Enhanced Heavy Attack: Forte Illation - Deals Spectro damage, generates good Concerto Energy, converts all “Collapsed Cores” into “Flare Star Butterflies” instantly, and slightly pulls Non Elite/Boss enemies to the center of the ability gathering them.

Both abilities are similar, but Forte Illation is preferred as it doesn’t require you to be in Mid-Air and also features Pull, as such use it whenever you have 5 “Empirical Data” to generate additional Concerto Energy and expedite the conversion of “Collapsed Cores” into Concerto generating “Flare Star Butterflies”.

To activate these Forte Abilities, we will need to use her Basic Attacks - mainly her standard 4 Basic Attack combo, which is:

• Basic Attack 1 (Generates 1 “Collapsed Cores” and 1 “Empirical Data”)

• Basic Attack 2 (Generates 1 “Collapsed Cores” and 1 “Empirical Data”)

• Basic Attack 3 (Generates 1 “Collapsed Cores” and 2 “Empirical Data”)

• Basic Attack 4 (Generates 1 “Collapsed Cores” and 1 “Empirical Data”)

The combo generates enough “Empirical Data” and “Collapsed Cores” to immediately follow up with an enhanced Forte attack of your choice (Illation recommended) after which all Cores will convert to “Flare Star Butterflies” generating a burst of Concerto Energy. Furthermore, her Dodge Counter also generates strong Concerto Energy but should be only utilized if a situation arises.

Shorekeeper’s Resonance Skill isn’t overly connected to the rest of her kit but is an excellent tool for a burst of healing and concerto generation. Using it grants 20 Concerto energy immediately, heals the party for a decent amount instantly, and summons 5 “Dim Star Butterflies” which operate identically to “Flare Star Butterflies”. Overall, the ability grants 30 Concerto after the butterflies find their target and only has a 16-second cooldown - use it whenever it’s available and you aren’t full on concerto. As a bonus using Basic Attacks right after this ability will skip straight to Basic Attack 2 of the combo.

Lastly let's talk about The Shorekeeper's Intro skill, which she has two of - a standard one and an empowered one accessible only once per Resonance Liberation used. Both Intro skills heal, deal damage, and generate good Concerto Energy, but the empowered one does it all better at the cost of immediately ending the current Stellarealm regardless of the duration left.

This might look like a steep cost to pay, but when played optimally you should be only switching Shorekeeper in when she needs to refresh the Stellarealm anyway, making this downside negligible. On the upside, empowered Intro generates double Concerto Energy, deals damage based on her HP instead of Attack (resulting in a surprisingly large damage nuke), always hits Critically, and heals slightly more. With all these bonuses, you should always aim to execute the empowered Intro if possible, and the damage dealt is non-negligible if you decide to build into it.

Rounding off her kit is her Inherent Skills:

• The first offers the standard Cheat Death ability we expect from healing characters protecting a fatally wounded ally by transferring half of Shorekeeper’s HP to it instead.

• The second one grants Shorekeeper 10% additional Energy Regen while any Resonator is within the Stellarealm radius (counting towards the 250% Bonus) meaning you only need to get 240% now! As an extra bit of flavor, if Rover is in the team, they too gain the 10% Energy Regeneration bonus.

In conclusion, Shorekeeper has a packed-to-the-brim supportive kit with excellent healing capabilities but she has a strong reliance on Concerto Energy generation tools such as her Intro and the weapons - Variation or Stellar Symphony (her Signature), without which she will feel less smooth. This can lead to her having weak openers in endgame modes lacking immediate Intro access - such as Tower of Adversity, and longer rotations for those lacking either weapon option.

However, if you are able to overcome these limitations, she is absolutely a meta powerhouse featuring some of the best supportive capabilities and flexibility in the game.
