Lauma in Genshin Impact Nod-Krai version is gradually becoming a prominent name, with the ability to activate and strengthen extremely powerful Grass reactions. If you are looking for a way to optimize Lauma's power, this article from Hobiverse will guide you on how to build Lauma effectively, from relics, weapons to skills.
Lauma's Power in Genshin Impact
Lauma is a special Grass-type character in Genshin Impact, with a different operating mechanism compared to many other characters in the game. Instead of relying on attacks or active skills, Lauma's strength comes largely from his talents, especially the ability to activate and improve Grass reactions. To maximize Lauma's potential, choosing holy relics, weapons, as well as how to upgrade skills is extremely important.
These talents not only help Lauma increase his damage but also have the ability to strongly support the whole team. One of the most notable is the talent Light for the Night Mist, which gives reactions like Abundance, Bloom and Unleash of the team a critical rate, something that these reactions did not have before.

Furthermore, Lauma also has the ability to activate Moon-Summer, a variation of the Sumer reaction. This reaction does not deal direct damage but after 2.5 seconds creates Blue Mist (the moon icon next to Lauma), a special resource that can be used to activate Lauma's elemental skills, which enhances the damage of Grass reactions. This helps Lauma not only effectively support in dealing damage but also can add a strong amount of damage to the whole team.
How to Build Lauma: Achieve high elemental mastery (TTNT)
To build a strong Lauma, the most important thing is to achieve a high Elemental Mastery (TTNT) stat. This is an important stat that increases the damage of Grass reactions, while also fully activating Lauma's talents. The goal is to reach at least 800 TTNT, because when reaching this threshold, Lauma's talents will be at their maximum effectiveness, such as Moon-Sum Sue reaching a maximum of 14%. If possible, you can try to increase TTNT even higher to increase damage.
After reaching the required level of TTNT, you should prioritize upgrading skills such as elemental skills (E) and rage (Q). Lauma's elemental skills help activate Grass reactions and reduce the enemy's Water and Grass resistance, an extremely important factor in optimizing damage for the whole team. In particular, you should also upgrade rage to increase the amount of Blue Hymn, which helps increase damage for reactions such as Sum Sue and Moon-Sum Sue.

Build a holy relic for Lauma
When choosing relics for Lauma, you should prioritize items with high TTNT, especially cups, clocks, and hats. The goal is to ensure Lauma reaches at least 800 TTNT to optimize her talents and skills. You can refer to some of the following relic sets:
-
4x Silk Moon Song: This is an ideal relic set for support characters like Lauma, increasing the team's energy and ATK by 20%.
-
4x Lost Flower of the Manor: Increases ATK to 800 and helps Lauma deal damage from Grass reactions.
-
4x Deep Forest Memory: Reduces enemy's Grass resistance and increases damage to Grass reactions.
-
Mix 2-piece sets to increase TTNT: If you don't have special relic sets, you can combine 2-piece sets to achieve high TTNT stats.
Weapons for Lauma
Weapons are an equally important factor in building Lauma. Since Lauma relies heavily on AI, you should prioritize weapons with high AI stats. Some suitable weapons for Lauma include:
-
Night Weaver Glass: A 5-star weapon exclusive to Lauma, providing extremely high TTNT and a strong damage buff to Thao reactions.
-
Priestly Gaze: Despite his high ATK, Lauma cannot create a shield, so he cannot take full advantage of this weapon.
-
Morning Slumber: Provides TTNT, but is limited as Lauma cannot activate the Diffusion effect.
-
Black Marrow Lamp S5: A weapon crafted in Nod-Krai that increases the damage of Sum Sue and Moon-Sum Sue.

Lauma's gameplay and rotation
Lauma's gameplay revolves around using Blue Mist and Moonlight to increase the damage of his Grass reactions. There are a few simple steps to remember in Lauma's rotation: after activating the Moonlight reaction, you will receive Blue Mist. Then, you hold E to convert each layer of Blue Mist into Moonlight and use your rage to activate Blue Hymn, which increases the damage of your Grass reactions.
This makes Lauma a powerful support character, not only increasing damage to Grass reactions but also reducing enemy Water and Grass resistance. Lauma can synergize extremely effectively with characters like Nilou or Furina, creating an extremely powerful Grass reaction lineup.
Don't hesitate any longer, build Lauma now by achieving enough TTNT, upgrading skills and choosing the right weapons and relics to maximize Lauma's power.
