Mualani build guide · GenGuru: Your guru for Genshin Impact

Overview

On-field Hydro damage
Vaporize carry

Mualani is a Natlan Hydro catalyst who fights on a shark surfboard. Her Elemental Skill puts her into Nightsoul's Blessing, where her Normal Attacks become Sharky's Bites that scale with her Max HP. Touching enemies marks them as prey and builds Wave Momentum, and at three stacks her next bite becomes a much stronger Surging Bite that also fires missiles at every marked enemy. Her Elemental Burst launches one large shark missile, which gets stronger when teammates trigger Nightsoul Bursts.

She hits in big, slow chunks, which makes her an excellent Vaporize carry. Give her HP, Hydro damage and crits, and pair her with Pyro characters who apply Pyro off the field.

Weapons

Best first. Every catalyst on this list links to its page.

Surf's Up ★★★★★
Her signature catalyst. Max HP, a huge CRIT DMG stat and a Normal Attack damage bonus that refills when she triggers Vaporize.
Tome of the Eternal Flow ★★★★★
HP and CRIT DMG as stats. The Charged Attack bonus does not help her, but the stats alone make it a strong option.
Jadefall's Splendor ★★★★★
A big HP stat and a small Hydro damage bonus after her Burst.
Ring of Yaxche ★★★★
The best 4-star choice. HP as a main stat and a Normal Attack damage bonus based on Max HP after she uses her Skill.
Sacrificial Jade ★★★★
CRIT Rate as a main stat. Its HP and Elemental Mastery bonus only builds while she is off the field and ends after she has been on the field for a while, so treat it mostly as a CRIT Rate stat stick.

Artifact sets

Obsidian Codex 4-piece
The best set. She is always in Nightsoul's Blessing while attacking, so both the damage bonus and the CRIT Rate bonus stay active.
Obsidian Codex + Tenacity of the Millelith 2-piece each
A stopgap: damage in Nightsoul's Blessing plus Max HP.
Heart of Depth 4-piece
Her bites count as Normal Attacks, so this set's bonus after using her Skill covers her whole combo.

Main stats and substats

Sands: HP% or Elemental Mastery
Goblet: Hydro DMG Bonus or HP%

Tips

Run through enemies before you bite to mark them and build Wave Momentum. A Surging Bite on a marked target also hits every other marked enemy with missiles.
Surging Bites leave Puffers behind. Pick them up to restore Nightsoul points and stay on the surfboard longer.
Make sure Pyro is on the enemy before your Surging Bite lands, so the biggest hit Vaporizes.
Because her bites count as Normal Attacks, bonuses to Normal Attack damage help her even though the bites scale with HP.
