For most Mualani builds, start with four-piece Obsidian Codex, HP% sands, a Hydro DMG goblet, and a CRIT circlet. Level her Elemental Skill first, and pair her with off-field Pyro to Vaporize her empowered Sharky’s Bite hits. Surf’s Up is a premium fit; The Widsith and craftable Ring of Yaxche are practical alternatives. Tune CRIT Rate carefully because Obsidian Codex adds a large amount during combat.
How Mualani deals damage
Mualani is an on-field Hydro damage dealer. Her Elemental Skill puts her into Nightsoul’s Blessing, where she builds power by tagging enemies with Sharky’s Bites before releasing empowered attacks. Those attacks account for much of her damage, so her build favors strong individual hits rather than treating her like a conventional rapid Normal Attack carry. Vaporize is a natural team choice because it amplifies those high-impact Hydro hits.
Best Mualani artifact set and stats
Default set: four-piece Obsidian Codex
Four-piece Obsidian Codex is the recommended default. The Version 7.1 Genshin-Builds reference reports that its effect grants 15% DMG Bonus and, after the equipping character consumes Nightsoul points, 40% CRIT Rate. Those bonuses suit Mualani’s Skill-based Nightsoul damage loop, but the CRIT Rate also makes overcapping a real build consideration.
Main stats
| Slot | Starting choice | When to reconsider |
|---|---|---|
| Sands | HP% | Compare the actual substats and team setup; Elemental Mastery can gain value when Mualani reliably triggers Vaporize. |
| Goblet | Hydro DMG Bonus | HP% can be competitive in some weapon and artifact combinations; compare the pieces rather than assuming one main stat always wins. |
| Circlet | CRIT Rate or CRIT DMG | Choose around your weapon, substats, and Codex’s combat CRIT Rate. The older Version 5.8 KeqingMains guide notes that an HP% circlet or goblet can compete in some builds using a CRIT DMG weapon and Codex. |
Substats and CRIT balance
Prioritize useful CRIT, then HP%; add Elemental Mastery when Vaporize is consistent in your team. There is no universal stat target that fits every weapon and lineup. Mualani’s ascension CRIT Rate plus Obsidian Codex’s 40% in-combat bonus can push a build toward excess CRIT Rate, especially with Sacrificial Jade. If that happens, favor CRIT DMG or HP% where your available pieces support it.

Interim artifact options
If your Codex pieces are not ready, four-piece Heart of Depth or two-piece combinations that grant HP%, Hydro DMG Bonus, or Elemental Mastery can bridge the gap. The Version 5.8 KeqingMains guide ranks Heart of Depth below Codex, so treat it as an interim or convenience set rather than the default end goal.
Best Mualani weapons
Weapon value depends on passive activation, refinement, artifact stats, and how reliably the team triggers reactions. The guides do not provide a shared damage-testing table across these options, so their recommendations should not be read as measured percentage differences.

| Weapon | Use case | Important caveat |
|---|---|---|
| Surf’s Up | Premium signature choice and a strong fit for Mualani. | It is an upgrade option, not a requirement for a functional build. |
| Reliquary of Truth | Another premium alternative included in newer build references. | Compare its passive with your team’s reaction pattern and available stats. |
| Tome of the Eternal Flow and EM catalysts | Other alternatives appearing in build guides. | Their relative value depends on the build; surfaced references do not establish one universal ranking. |
| The Widsith | Accessible four-star offensive option. | Its random passive means its performance is inconsistent between activations. |
| Ring of Yaxche | Craftable option with HP% and a Normal Attack bonus that fits her kit. | A practical accessible choice when premium weapons are unavailable. |
| Sacrificial Jade | Conditional offensive option. | Its CRIT Rate can contribute to overcap alongside Mualani’s ascension stat and Obsidian Codex. |
GameWith’s October 2, 2026 build page also lists the event weapon Ash-Graven Drinking Horn among free-to-play choices. Availability of event weapons can depend on when a player obtained them, so it is not a dependable substitute for a currently obtainable craftable weapon.
Talent priority
- Elemental Skill: Level this first; the enhanced Sharky’s Bite damage is associated with the Skill talent.
- Elemental Burst: Level this next.
- Normal Attack: Lowest priority for this build, since ordinary attack talent levels are a smaller investment than the Skill that supports her empowered hits.
Best Mualani teams
Build around off-field Pyro application so Mualani can Vaporize her large Hydro hits. Then choose resistance shred, buffs, and defensive support based on the roster and how comfortably the rotation works. The team examples below are options, not an unconditional best-in-slot ranking.

Vaporize: Mualani, off-field Pyro, shred or support, flex
Mavuika is described in current surfaced recommendations as offering reliable Pyro application and buffs. Durin is another current Pyro option, with an energy consideration. Xiangling and Pyro Traveler appear as alternatives in other guides. Fill the remaining slots with resistance shred, buffs, or comfort: Sucrose can share Elemental Mastery and shred resistance, while Xilonen is noted for longer-duration buffs and easier Hydro Scroll activation. Zhongli is an option when interruption protection is more valuable than another offensive support.
Burn-Vape and older examples
GameWith’s September 30, 2026 team page covers classic Vaporize, Burn-Vape, and Mono Hydro setups. Older recommendations also include Dehya, Zhongli, and Kazuha; treat these as roster-dependent examples rather than guaranteed best choices. Check whether the Pyro character actually maintains application through Mualani’s attacks, and whether the support effects line up with her damage window.

Mono Hydro
Mono Hydro is a simpler alternative in one surfaced guide, but that guide rates it below Vaporize and Burn-Vape. It can be considered when the available roster or preferred play pattern makes consistent reaction teams difficult.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to play Mualani and make the rotation comfortable
- Apply your team’s support effects and establish off-field Pyro application before Mualani’s main damage window.
- Use Mualani’s Elemental Skill to enter Nightsoul’s Blessing.
- Tag enemies with Sharky’s Bites to build stacks, then release empowered attacks while aiming at the target.
- Adjust movement and timing against mobile enemies rather than assuming a stationary rotation will connect equally well.
Targeting comfort matters: the surfaced guides describe building stacks by tagging enemies and releasing empowered attacks, so practice movement and aim against moving targets. Rotation ease and reliable Pyro uptime can be more useful than a theoretical support choice that is difficult to execute with your roster.

Source and version context
Recommendations here reflect surfaced build and team pages updated in 2026: Mobalytics’ build page was updated July 10, GameWith’s build page October 2, and its team page September 30. The Genshin-Builds reference labels itself Version 7.1; KeqingMains’ detailed quick guide is Version 5.8, so its CRIT and weapon caveats carry that version context. HoYoverse’s official skill showcase is dated August 22, 2024, but its page text does not expose readable skill lines for quoting.
