Lauma is a 5-star Dendro character in Genshin Impact. She acts as a specialized support driver, known as the "Moonchanter" of the Frostmoon Scions. This Lauma build guide for Genshin Impact covers all about her talent priorities, artifacts, weapons, team compositions, and more.

Lauma Character Overview

	Rarity	5-star
	Element	Dendro
	Weapon	Catalyst
	Combat Role	Support

Lauma is a 5-star Dendor Catalyst character from the Frostmoon Scions. She provides strong support for all pre-existing Bloom teams and adds Hydro and Dendro RES Shred, along with other Bloom-related buffs. She can also provide on-field Dendro application through her Catalyst Normal Attacks and off-field Dendro application from her Skill.

Lauma is the only character capable of enabling the Lunar-Bloom reaction, which replaces the standard Bloom reaction when she is in the party. Her abilities emphasize the Pale Hymn mechanic, which grants stacks when she deploys her Burst or consumes Verdant Dew. These stacks increase the damage of Burgeon, Hyberbloom, Bloom, and Lunar-Bloom reactions based on her Elemental Mastery. This makes her a powerful reaction buffer that elevates the team's overall damage output.

Lauma's Ascension 1 Passive and Elemental Burst strengthen the entire party's Bloom reaction damage, while her off-field Skill hits carve through enemy Hydro and Dendro resistance.

Talent Priority

The recommended skill upgrade priority for Lauma build in Genshin Impact is:

Elemental Skill (E) > Elemental Burst (Q) > Normal Attack (A)

Recommended Resource Allocation

Lauma Best Weapons

Nightweaver's Looking Glass is Lauma's signature weapon. It's the only weapon that feeds all three pillars of Lunar-Bloom damage simultaneously: 265 Elemental Mastery, a 200% Lunar-Bloom exclusive multiplier, and enough CRIT stats to make every hit count.

This weapon also handles what most support weapons ignore entirely. Off-field energy regeneration keeps her Burst on cooldown, while the on-field Dendro and Hydro DMG bonus extends her value to teammates even when she isn't active. Lunar Bloom damage can drop by 25-40% without this weapon.

Check the following table for a clear Lauma weapons ranking:

Name	Base ATK	Elemental Mastery	Weapon Effect
Signature Weapon
Nightweaver's Looking Glass	542	+264.6	Dealing Hydro or Dendro DMG via Elemental Skill grants 60-120 EM for 4.5s. Nearby Lunar-Bloom triggers add another 60-120 EM for 10s. When both are active simultaneously, the entire party gains 120-240% Bloom DMG, 80-160% Hyperbloom/Burgeon DMG, and 40-80% Lunar-Bloom DMG. All stackable off-field.
5-star Alternatives
Sunny Morning Sleep-In	542	+264.6	Swirl grants 120-240 EM for 6s; Elemental Skill hits add 96-192 EM for 9s; Elemental Burst hits stack on 32-64 EM for 30s.
Starcaller's Watch	542	+264.6	Increases 100-200 EM baseline. Triggering a shield activates Mirror of Night, which increases the active character's DMG by 28-56% against nearby enemies for 15s (once every 14s).
A Thousand Floating Dreams	542	+264.6	Each party member buffs the wielder based on Element. Same Element grants 32-64 EM, different Element grants 10-26% DMG Bonus, up to 3 stacks. All other party members also receive 40-48 EM. Stackable across multiple copies.
4-star Alternatives
Blackmarrow Lantern	454	+220.5	48-96% Bloom DMG and 12-24% Lunar-Bloom DMG. Moonsign: Ascendant Gleam pushes Lunar-Bloom DMG up by an additional 12-24%.
Sacrificial Fragments	454	+220.5	Elemental Skill hits have a 40-80% chance to fully reset the Skill's cooldown (once every 30-16s).
Wandering Evenstar	510	+165.4	Every 10s, converts 24-48% of the wielder's EM into bonus ATK for 12s. Nearby party members inherit 30% of that ATK buff. Stacks with multiple copies; triggers off-field.
Favonius Codex	510	+45.9	CRIT hits have a 60-100% chance to generate particles, restoring 6 Energy (once every 12-6s).

Lauma Best Artifact Sets

Since virtually every part of Lauma's kit scales off Elemental Mastery and Dendro reactions, EM-focused artifacts become the foundation. Silken Moon's Serenade is built for Lunar-Bloom, which makes it one of the uncontested best artifacts for Lauma.

Its 4-piece effect delivers on two fronts:

1. A 50% Lunar-Bloom DMG increase that functions as an independent multiplier. It stacks multiplicatively with her talent and weapon scaling for outsized returns.
2. A teamwide +120 EM aura for 12s upon trigger, which sharpens Lauma's own reaction damage and empowers EM-reliant teammates, such as Shinobu, Kuki, Nilou, and Thoma.

Every layer of this set (the damage multiplier, the EM aura, the trigger condition) maps directly onto Lauma's rotation and team role.

Name	Effect
Best Choice
Silken Moon's Serenade	2-Pc: +20% Energy Recharge4-Pc: Dealing Elemental DMG grants all party members +60/120 EM (Nascent/Ascendant Gleam) for 8s. Each unique Gleaming Moon effect active across the party adds +10% Lunar Reaction DMG. Triggers off-field.
Alternatives
Night of the Sky's Unveiling	2-Pc: Increases Elemental Mastery by 804-Pc: Nearby Lunar Reaction triggers grant the on-field wielder +15%/30% CRIT Rate (Nascent/Ascendant Gleam) for 4s, plus +10% Lunar Reaction DMG per unique Gleaming Moon effect.
Gilded Dreams	2-Pc: Increases Elemental Mastery by 804-Pc: Within 8s of triggering a reaction, gain +14% ATK per same-Element teammate and +50 EM per different-Element teammate (up to 3 counts each). Refreshes every 8s and triggers off-field.
Beginner Choice
Gilded Dreams	2-Pc: Increases Elemental Mastery by 80
Wanderer's Troupe	2-Pc: Increases Elemental Mastery by 80

Best Lauma Team Compositions

Lauma integration into the Hydro-Dendro-Electro triangle leads to continuous Lunar Bloom explosions.

The team building formula for Lauma is:

Dendro + Hydro + Lauma + Flex Support/Sub-DPS

For example, the best Lauma team composition is: Columbina + Lauma + Aino + Nefer

• Aino's Hydro triggers Bloom, Lauma converts cores into Lunar-Bloom, and Columbina chains off them to detonate high-frequency Petal-Burst instances.
• Nefer sustains Dendro application and deals serious personal damage. Columbina passive feeds off the team's combined EM, which creates a compounding AoE damage loop.
• Lauma's C1 healing and Aino's Hydro shielding, along with Nefer's DMG reduction, cover all sustain angles. This makes the team self-sufficient even in Spiral Abyss Floor 12.

The following are all the recommended team compositions for Lauma build in Genshin Impact:

Lauma Lunar-Bloom Team

Main DPS	Support		Flex
Nefer	Lauma	Nilou	Columbina
Columbina	Lauma	Nilou	Nahida

Lauma Bloom Teams

Support	Hydro Applier		Dendro Applier
Lauma	Nilou	Kokomi	Nahida
Lauma	Nilou	Yelan	Baizhu
Lauma	Xingqiu	Barbara	Yaoyao

Lauma Hyperbloom Teams

Dendro Applier		Hydro Applier	Electro Applier
Lauma	Nahida	Yelan	Shinobu
Lauma	Nahida	Xingqiu	Shinobu
Lauma	Alhaitham	Xingqiu	Shinobu
Lauma	Dendro MC	Xingqiu	Shinobu

Conclusion

Lauma is among the few support characters that reshape an entire team's damage profile. When you drop her into any Hydro-Dendro composition and feed her Elemental Mastery, you will watch Bloom reactions elevate beyond anything a standard Bloom team can achieve. So, we will wrap up our Lauma Lunar-Bloom build guide by declaring her a must-pull character.
