Who Is Mualani in Genshin Impact?

Mualani is a 5-star Hydro Catalyst character in Genshin Impact, introduced in Version 5.0 as one of the flagship characters of the Natlan region. She is a member of the People of the Springs (Meztli tribe) — a group whose ancestors were legendary explorers who mapped the world with their own feet. True to that heritage, Mualani is Natlan’s most enthusiastic and knowledgeable tourism guide, running her own watersports shop and sharing the wonders of her homeland with anyone willing to listen.

Her cheerful, outgoing personality is one of the most infectious in the game. She rides a surfboard shaped like a shark — a companion she calls Sharky — and brings that same playful energy into every battle. Her combat kit is built around the Nightsoul mechanic introduced with Natlan, letting her surf around enemies, build momentum stacks, and detonate everything into a single devastating hit.

In the game’s lore, the People of the Springs have a deep connection to water and are closely tied to the Hydro element. Mualani is also one of the characters linked to Natlan’s ongoing conflict against the Abyss, placing her within the broader narrative of Version 5 alongside heroes like Kinich and Xilonen.

You can play Genshin Impact on Android, iOS, PlayStation, Epic Games, and Xbox.

Mualani

Mualani’s Role and Playstyle

Mualani is a Hydro Hypercarry Main DPS who stays on-field and delivers devastating single-hit nukes through her Elemental Skill’s enhanced Normal Attack mechanic. Her playstyle revolves around the following loop:

• Use her Elemental Skill to activate Nightsoul’s Blessing and mount Sharky the surfboard.
• Ride into enemies to tag them, gaining Wave Momentum stacks (up to 3 per skill use). Each collision also collects a Puffer near the tagged enemy.
• Once you’ve tagged enough enemies and are ready to deal damage, use her enhanced Normal Attack — Sharky’s Surging Bite — which hits all tagged enemies simultaneously and fires additional Shark Missiles at them.
• Use her Elemental Burst between Skill uses for additional Hydro damage and to reset her Nightsoul points.

Her damage is concentrated into large infrequent nukes rather than rapid small hits. Each Sharky’s Surging Bite hits extremely hard, especially when Vaporize is triggered. She is primarily a single-rotation burst DPS who maximizes the Vaporize reaction window.

She excels in Vaporize teams where Pyro characters apply and maintain a Pyro aura on enemies, letting Mualani trigger Reverse Vaporize with her Hydro hits for 1.5x amplified damage. She also benefits from high HP totals since her damage scales directly with her Max HP.

Mualani’s Abilities and Talents

Normal Attack – Cooling Treatment

Mualani performs up to three Hydro catalyst attacks. Her Charged Attack and Plunging Attack also deal Hydro DMG. However, her enhanced Normal Attack (Sharky’s Surging Bite) triggered during Nightsoul’s Blessing state is a completely different and far more powerful ability that scales with her Elemental Skill talent level — not her Normal Attack level. Because of this, there is no need to level her Normal Attack talent in most builds. It is the lowest priority by a significant margin.

Elemental Skill – Surfshark Wavebreaker

This is the heart of Mualani’s entire kit. She mounts Sharky and enters Nightsoul’s Blessing state, gaining access to the following mechanics:

• She surfs around on-field and collides with enemies to deal Hydro DMG and apply the Wavechaser’s Mark to them.
• Each enemy hit grants one Wave Momentum stack (max 3). Stacks increase the power of Sharky’s Surging Bite and the number of Shark Missiles fired.
• Collecting Puffers (small fish that appear near marked enemies) restores Nightsoul points, extending her Blessing state.
• Once ready, using a Normal Attack triggers Sharky’s Surging Bite — a massive AoE Hydro hit on all marked enemies, followed by a Shark Missile barrage that scales with Wave Momentum stacks.

This is her top priority talent to level. The Surging Bite multiplier, the Shark Missiles, and all her Skill damage scale off this talent’s level. Level it to 9 or 10 as a priority.

Elemental Burst – Boomsharka-laka

Mualani leaps into the air and dives forward on Sharky, dealing AoE Hydro DMG across a wide area. This Burst also replenishes her Nightsoul points, allowing her to re-enter the surfing state and continue her rotation. It is her second talent priority and is worth leveling to at least 8–9.

1st Ascension Passive – Heat-Resistant Freshwater Floater

This passive unlocks when Mualani reaches her 1st Ascension. While in Nightsoul’s Blessing, when she obtains a Puffer, she recovers Nightsoul points and deals bonus damage with Boomsharka-laka (75% increased DMG with C4, but base power from this passive alone is meaningful). This passive is essential for extending her Skill uptime and is unlocked automatically through ascension.

4th Ascension Passive – Natlan’s Greatest Guide

Mualani gains an Elemental DMG Bonus based on her Max HP during Nightsoul’s Blessing state. Since she scales with HP, this passive essentially converts more HP into damage in a direct and clean way, making investing in HP% even more rewarding.

Utility Passive – The Trick Is to Keep Smiling!

Restores Phlogiston when Mualani interacts with certain resources in Natlan. Also reveals the location of nearby resources unique to Natlan on her mini-map. An extremely convenient exploration passive that helps you gather Natlan local specialties for all your Natlan characters.

Talent Priority for Mualani

• Elemental Skill first – Surfshark Wavebreaker controls Sharky’s Surging Bite, Shark Missile damage, and all of her core output. Max this first.
• Elemental Burst second – Boomsharka-laka deals good AoE Hydro damage and enables her rotation. Worth leveling to at least 8.
• Normal Attack — do not level – This is one of the rare characters in the game where leveling Normal Attack provides zero benefit. Her enhanced Surging Bite scales with Skill talent, not Normal Attack. Do not spend talent materials here.

Best Weapons for Mualani

5-Star Weapons

• Surf’s Up (Signature) – Her best-in-slot weapon without question. Provides a massive HP% secondary stat, high CRIT DMG, and a passive that directly buffs Normal Attack DMG (which includes Sharky’s Surging Bite). Perfectly designed around her entire kit. If you pull Mualani, pulling for Surf’s Up is highly worthwhile.
• Tome of the Eternal Flow – An excellent second option. Provides CRIT DMG and a passive that increases HP-scaling damage. Works naturally with Mualani’s HP-dependent damage model and is a strong alternative if you already have it on another character.
• Cashflow Supervision – Provides CRIT Rate and increases Normal Attack and Charged Attack DMG when the character’s HP changes. Strong in teams with Furina where HP fluctuates frequently.

4-Star Weapons

• Sacrificial Jade – Provides CRIT Rate, which Mualani values, and a passive that increases HP and Elemental Mastery after not being the active character. Works well in quick-rotation team plays and gives her good CRIT Rate baseline to work with.
• Ring of Yaxche (Craftable, Natlan) – A craftable weapon from Natlan that provides HP% and directly buffs Mualani’s Normal Attack DMG during Nightsoul’s Blessing. One of the best free-to-play options specifically made for her playstyle. Highly recommended for players who cannot obtain premium catalysts.
• The Widsith – Provides CRIT DMG and a random buff on-field entry (ATK%, Elemental DMG%, or EM). The peak damage ceiling is high when the Elemental DMG or EM buff lands, but the randomness is a drawback for consistent performance.
• Prototype Amber (Craftable) – Provides HP% and restores Energy and HP to team members when the Burst is used. Not a damage-focused pick but helps with team survivability in teams without a healer. A functional F2P fallback.

Best Artifacts for Mualani

Primary Build – 4-Piece Obsidian Codex

This is her best artifact set by a wide margin and the one you should farm for. The 4-piece bonus grants Mualani a massive 40% CRIT Rate boost whenever she consumes a Nightsoul point — which happens constantly during her Skill state. This means she effectively has near-permanent high CRIT Rate during her damage window, allowing you to focus your artifact substats almost entirely on CRIT DMG rather than CRIT Rate. The result is a dramatically inflated damage output compared to other sets. Run this set on Mualani in virtually every team.

Alternative – 4-Piece Marechaussee Hunter

Provides Hydro DMG Bonus and stacking CRIT Rate when the character’s HP changes. Works well specifically in teams with Furina, where HP fluctuates constantly during her Burst, keeping the CRIT stacks active. However, it requires Furina to be present and makes you team-locked to that specific setup. Generally Obsidian Codex is still better even with Furina due to the consistency advantage.

Alternative – 4-Piece Unfinished Reverie

Provides ATK% and a massive DMG Bonus buff that ramps up while the character is off-field or after a Burning reaction occurs. Only applicable in Burning Vaporize team setups. A niche option for very specific team compositions.

Recommended Artifact Main Stats

• Sands: HP%
• Goblet: Hydro DMG Bonus
• Circlet: CRIT DMG (since Obsidian Codex handles CRIT Rate) or Elemental Mastery (for EM-focused Vaporize builds)

Recommended Substats

CRIT DMG > HP% > CRIT Rate (only if below 40–50% with Obsidian Codex bonus) > Elemental Mastery > Energy Recharge. With the Obsidian Codex 4-piece active, you rarely need much CRIT Rate from substats. Focus on stacking CRIT DMG and HP% for maximum Sharky’s Surging Bite damage.

Best Team Compositions for Mualani

Mualani Vaporize Team #1 (Top Tier)

• Mualani (Main DPS) + Xilonen (Geo Support / RES Shred) + Xiangling (Pyro Sub-DPS) + Zhongli (Shielder)

This is consistently ranked as Mualani’s best team. Xiangling applies persistent off-field Pyro with Pyronado, giving Mualani’s Hydro hits a constant Vaporize trigger for massive amplified damage. Xilonen shreds enemy elemental resistance and provides healing through her unique Geo infusion mechanics. Zhongli’s near-impenetrable shield keeps Mualani safe so she can surf freely and land every hit without interruption. A complete and powerful team with strong synergy at every slot.

Mualani Vaporize with Furina

• Mualani (Main DPS) + Xilonen (Support) + Furina (Hydro Sub-DPS) + Xiangling (Pyro)

Furina’s unique HP-fluctuating mechanics and massive DMG Bonus buffs elevate Mualani’s damage ceiling. Furina‘s Burst gives all party members a DMG Bonus that scales with the total HP lost and restored across the team. Since Mualani has high HP, Furina’s buff hits harder on her. Xilonen handles RES shred and healing to keep the team healthy for Furina’s HP-fluctuation mechanic. Xiangling provides Vaporize as usual.

Mualani Vaporize Budget Team

• Mualani (Main DPS) + Xiangling (Pyro Sub-DPS) + Yelan (Hydro Sub-DPS) + Citlali (Cryo Support)

Xiangling provides off-field Pyro for Vaporize. Yelan adds extra Hydro damage from off-field and a DMG Bonus buff through her Burst passive. Citlali provides Cryo application for Frozen or Shattered sub-reactions and shields. A strong team that uses widely available characters and still performs well in Spiral Abyss.

Mualani Natlan Premium Team

• Mualani (Main DPS) + Xilonen (Support) + Citlali (Cryo) + Mavuika (Pyro)

A fully Natlan-centric team with multiple Nightsoul characters. Mavuika provides powerful Pyro application and Nightsoul-synergized buffs. Citlali adds Cryo and sub-reactions. Xilonen handles RES shred and healing. Mualani rides Sharky and delivers enormous Vaporize or Melt-enabled Hydro hits. A high-ceiling premium team for endgame players who have invested in the Natlan roster.

Mualani Burning Vaporize (Niche)

• Mualani (Main DPS) + Emilie (Dendro) + Xiangling (Pyro) + Dehya (Pyro)

A specialized composition that uses Burning to maintain a persistent Pyro aura on enemies, protecting Xiangling’s Pyro from being consumed and giving Mualani a more reliable Vaporize trigger. Emilie applies Dendro for Burning uptime. Dehya provides additional Pyro application and some survivability. A niche but functional setup for players who want to experiment with Burning Vaporize.

Mualani Constellations Guide

Mualani is a 5-star character, making constellations expensive. Fortunately, she is strong at C0. Here is what each constellation provides:

• C1 – The Leisurely “Meztli”…: The first Sharky’s Surging Bite Mualani uses after entering Nightsoul’s Blessing deals bonus damage equal to 66% of her Max HP. This is a direct and enormous damage increase to her biggest hit every rotation. This is her most impactful constellation and meaningfully raises her damage floor. Additionally, Nightsoul’s Blessing consumes 30% less Phlogiston and Nightsoul points out of combat, improving exploration efficiency.
• C2 – Mualani, Going All Out!: Mualani gains 2 Wave Momentum stacks immediately when entering Nightsoul’s Blessing (instead of building from 0). She also gains 1 stack when collecting a Puffer. Additionally, collecting 2 Puffers in a single Blessing instance regenerates 12 Nightsoul points over 2 seconds. This significantly speeds up her rotation and improves Nightsoul uptime.
• C3 – Waves Surging with Momentum: Increases Surfshark Wavebreaker (Elemental Skill) level by 3 (max level 15). A direct damage upgrade to her primary ability.
• C4 – Deepwater Predator: Mualani regenerates 8 Energy when obtaining a Puffer. Boomsharka-laka (Elemental Burst) also deals 75% increased DMG. Both of these are meaningful upgrades — better Burst uptime and a major Burst damage boost.
• C5 – Same Style of Surfboard on Sale!: Increases Boomsharka-laka (Elemental Burst) level by 3 (max level 15). Enhances Burst damage further.
• C6 – Sharky’s Super Splash: The C1 DMG bonus is no longer limited to once per Nightsoul’s Blessing. Every Sharky’s Surging Bite Mualani uses during Nightsoul’s Blessing now deals the bonus damage equal to 66% of her Max HP. This effectively doubles the power of C1 when she activates Nightsoul’s Blessing multiple times per rotation — a massive endgame power spike for dedicated players.

Summary: C1 is the most impactful single constellation upgrade and highly recommended if you’re spending on her banner. C0 is fully viable for all content. C6 is exceptional for players who love Mualani and want to push her ceiling as far as possible.

Mualani Ascension Materials

To fully ascend Mualani from Level 1 to Level 90, you need:

• Varunada Lazurite (Sliver, Fragment, Chunk, Gemstone) – Dropped by Hydro-aligned bosses including the Hydro Hypostasis, Oceanid, Coral Defenders, Hydro Tulpa, and others across Teyvat.
• Mark of the Binding Blessing – Dropped by the Goldflame Qucusaur Tyrant, a field boss located in the underground Basin of Unnumbered Flames beneath Huitztli Hill in Natlan. Costs 40 Original Resin per claim. You need 46 total.
• Sprayfeather Gill – Mualani’s local specialty, found in Natlan around Toyac Springs and the People of the Springs area. There are roughly 73 in the overworld. They regrow over time. Mualani’s own Utility Passive reveals nearby Natlan specialties on the mini-map, making this easier to farm on her own account.
• Tribal Warrior Whistles (Sentry’s Wooden Whistle, Warrior’s Metal Whistle, Saurian-Crowned Warrior’s Golden Whistle) – Dropped by Sauroform Tribal Warrior enemies found throughout Natlan. Also available through the in-game shop for Stardust.

Mualani Talent Materials

To fully upgrade all three of Mualani’s talents, you need:

• Teachings, Guide, and Philosophies of Contention – Obtained from the Blazing Ruins domain in Natlan on Mondays, Thursdays, and Sundays.
• Tribal Warrior Whistles (all three tiers) – Same drops as ascension material. Farm Sauroform Tribal Warriors in Natlan.
• Lightless Mass – A weekly boss drop from defeating the All-Devouring Narwhal, found in the underwater Salacia Plain area in Fontaine. Unlocked by completing the Masquerade of the Guilty Archon Quest in Fontaine, or accessible via Quick Challenge in your Handbook. You need 18 total across all talents.
• Crown of Insight – Needed to max any talent to level 10. Obtained from limited-time events and special offerings.

As noted in the Talent Priority section, you do not need to level Mualani’s Normal Attack talent at all. Focus all talent materials on her Elemental Skill and Elemental Burst.

Should You Pull for Mualani?

Mualani is one of the strongest Hydro DPS characters in Genshin Impact. She is an excellent pull if:

• You want a powerful Hydro Main DPS who carries through Vaporize reactions.
• You enjoy high-impact, on-field DPS playstyles with a fun and unique movement mechanic.
• You already have or plan to build Xiangling and Xilonen, who are her best teammates.
• You want a Natlan character who works in both Natlan-specific and universal team compositions.

She is less ideal if you prefer fast-paced Normal Attack spam DPS (her rotation is slower and nuke-focused). She also requires staying on-field during her Skill state, which demands some spatial awareness to tag enemies correctly before delivering the big hit.

Mualani Quick Tips

• Do not level her Normal Attack talent. Sharky’s Surging Bite scales off her Elemental Skill talent. All your talent materials should go to Skill and Burst only.
• Reach Level 90 as a priority. Her HP-scaling and her 4th Ascension Passive’s DMG bonus both benefit directly from maximum level. Do not stop at Level 80.
• When surfing, try to tag multiple enemies in one pass to collect all 3 Wave Momentum stacks efficiently before releasing Sharky’s Surging Bite. More stacks means more Shark Missiles and more total damage.
• With the Obsidian Codex 4-piece, you rarely need more than 40–50% base CRIT Rate from artifacts since the set gives 40% CRIT Rate during Nightsoul’s Blessing. Stack CRIT DMG and HP% on your substats instead.
• Apply Pyro aura to enemies before surfing into them. Mualani’s Hydro hits on Pyro-afflicted enemies trigger Vaporize immediately. Sending Xiangling’s Pyronado first, then activating Mualani’s Skill, ensures every hit she lands during surfing triggers a reaction.
• Her Boomsharka-laka Burst restores Nightsoul points. Use it between Skill activations to maintain continuous surfing momentum across rotations.
• Mualani has high interruption resistance while surfing. This makes her more comfortable to play without a shield in some situations, though a shield from Zhongli still provides the safest environment for landing the Surging Bite nuke.
