Geo support who combines team healing, resistance reduction, and Lunar-Crystallize support. Consider Linnea when your party can trigger Hydro Crystallize and you want her DEF to support both healing and that reaction.
Released Apr 8, 2026
Linnea is a Geo bow character whose summon Lumi attacks nearby enemies, reduces their Geo RES, and can heal the active character through her Burst. Her passive converts party members’ Hydro Crystallize reactions into Lunar-Crystallize, with a DEF-based bonus to that reaction’s Base DMG. Her value therefore depends on having Hydro Crystallize triggers and, for the extra Elemental Mastery benefit, a Moonsign character active.

Linnea GUIDE
Understand Linnea
Useful when…
Support a party that triggers Hydro Crystallize and can use Lunar-Crystallize.
Provide nearby Geo RES reduction and DEF-scaling healing while Lumi is active.
Gather ore with Lumi’s special out-of-combat Aimed Shot interaction.
What do Lumi and the Burst do?
Linnea’s Skill summons Lumi for 25 seconds on an 18-second cooldown. A tap makes Lumi attack nearby enemies continuously with AoE Geo DMG; when Moondrifts are nearby, Lumi also deals AoE damage counted as Lunar-Crystallize Reaction DMG. After the Skill, repeated Skill or Normal Attack taps feed Lumi gemstones; a full-bellied Lumi makes one especially powerful AoE hit counted as Lunar-Crystallize, then switches to Standard Power Form. Tapping the Skill also increases Linnea’s interruption resistance. Her Burst summons Lumi in Super Power Form for an initial heal and then heals the nearby active character continuously for 12 seconds based on Linnea’s DEF. If Lumi is already on field when she Bursts, its duration resets and its Strike Form does not change.
When does her support matter?
While Lumi is present, nearby opponents lose 15% Geo RES. With Moonsign: Ascendant Gleam, Linnea’s Skill and Burst are enhanced and the nearby opponents’ Geo RES is reduced by a further 15%. Her Moonsign Benediction converts party members’ Hydro Crystallize reactions into Lunar-Crystallize. Each 100 DEF Linnea has increases Lunar-Crystallize Base DMG by 0.7%, up to 14%; reaching the cap therefore requires 2,000 DEF. She also raises the party’s Moonsign by one level. Her Elemental Mastery passive grants the current active character 5% of Linnea’s DEF as EM if that character is a Moonsign character; otherwise Linnea receives that EM herself.
What should you prioritize?
DEF has direct support value: it scales the Burst healing and the Lunar-Crystallize Base DMG bonus, while also determining the size of the conditional EM increase. Consider DEF investment first when you want those functions; her Skill damage is also labeled as DEF-scaled. The Skill is the relevant talent to raise for Lumi’s attacks, while Burst levels improve its healing. Her bow Normal and Charged Attacks are separate: a fully charged crystalline arrow deals Geo DMG, but the basic attack talent is a lower priority if she is being used for her summon and support effects rather than on-field attacks. This is conditional guidance; no single stat target is established beyond the 2,000 DEF needed to cap the stated reaction bonus.
What limits or mistakes should you watch for?
The Lunar-Crystallize conversion requires a party member to trigger Hydro Crystallize; without that trigger, its conversion and DEF-based Base DMG bonus do not apply. The added Geo RES reduction requires the specified Moonsign condition. The Elemental Mastery passive follows the current active character condition, so it does not always buff the on-field teammate. Linnea’s exploration arrow deals only 20% of her normal Charged Arrow damage against opponents, and repeated use within a short period eventually requires a temporary break. Her ore interaction is a utility feature, not evidence of combat damage value.
Limitations and tradeoffs
Her reaction support depends on Hydro Crystallize triggers and is more specialized than general Geo support.
DEF serves several functions, but the given effects do not establish that maximizing DEF is always preferable to other build needs.
The available comparison candidates are Geo characters, but their records here only establish element, weapon, and rarity; those facts alone do not establish equivalent support roles.
Common mistakes to avoid
Expecting the Lunar-Crystallize conversion without a party member triggering Hydro Crystallize.
Assuming the EM passive always buffs the active teammate; it instead buffs Linnea when the active character is not a Moonsign character.
Treating the exploration arrow as a combat damage option despite its reduced damage and temporary-use limit.

Adventure with Lumi! Depending on how you Tap, Lumi attacks in different forms.
Tap Lumi strikes in a **Super Power Form**, attacking nearby enemies continuously, dealing AoE Geo DMG. If there are Moondrifts nearby, Lumi will also deal AoE Geo DMG to nearby enemies, which will be considered Lunar-Crystallize Reaction DMG.
Continuous Tapping Time to show what we're really capable of! After using her Elemental Skill, Linnea will feed Lumi sparkling gemstones when her Elemental Skill or Normal Attack is Tapped repeatedly. A full-bellied Lumi will strike in her **Ultimate Power Form**, dealing an especially powerful instance of AoE Geo DMG that is considered Lunar-Crystallize Reaction DMG, switching to **Standard Power Form**. Additionally, tapping the Elemental Skill increases Linnea's interruption resistance.

Even master adventurers need proper rest! Linnea summons Lumi to strike in **Super Power Form**, healing nearby party members. For a short duration, she will continuously heal nearby active party members based on Linnea's DEF. If Lumi is already on the field when Linnea unleashes Elemental Burst, Lumi's active duration will be reset instead and her Strike Form will not change.

Moonsign: Ascendant Gleam: Linnea's Elemental Skill **Countermeasure: Lumi's Battle Cry!** and Elemental Burst **Memo: Survival Guide in Extreme Conditions** are enhanced. After summoning Lumi, the Geo RES of opponents near Lumi will be further decreased by 15%.
Universal Naturalist Archive
Linnea will increase the Elemental Mastery of certain characters in your party according to your current active character. Increase in Elemental Mastery is based on 5% of Linnea's DEF. If your current active character: · Is a Moonsign character: Increase this character's Elemental Mastery. · Is not a Moonsign character: Increase Linnea's own Elemental Mastery.
Moonsign Benediction: Habitat Survey
When a party member triggers a Hydro Crystallize reaction, it will be converted into the Lunar-Crystallize reaction, with every 100 DEF that Linnea has increasing Lunar-Crystallize's Base DMG by 0.7%, up to a maximum of 14%.
Additionally, when Linnea is in the party, the party's Moonsign will increase by 1 level.

When Linnea is not in combat, the charge time of her Aimed Shot is greatly decreased, and she will shoot an Ultra Convenient Quick Arrow instead. Different effects will occur depending on the targets hit: · Specific animals: Ultra Convenient Quick Arrow will be transformed into a special "Net" that can capture the essence and form of these animals, using them as a medium to manifest the animal's physical form again. The "Net" can only be used for a limited number of times each week. · Ore veins used in forging: Linnea will dispatch Lumi, who will quickly strike at the ore marked by the Ultra Convenient Quick Arrow, then collect the dislodged ore. If Lumi is not on the field, Linnea will summon her for a short duration to help obtain the ore.
The DMG dealt to opponents by Linnea's Ultra Convenient Quick Arrow is reduced to 20% of her original Charged Arrow. Additionally, after firing a certain number of Ultra Convenient Quick Arrows within a short period of time, Linnea needs to take a temporary break before she can continue using them.
