Mualani

Hydro catalyst damage dealer who deals much of her damage through HP-scaling Sharky’s Bites while surfing in Nightsoul’s Blessing. Consider her when you can build Wave Momentum by moving into opponents and can take advantage of her marked-target missile hits.

Released Aug 28, 2024

Mualani is a five-star Hydro catalyst user. Her skill starts a surf state that converts normal attacks into HP-scaling Sharky’s Bites. Contact with opponents builds stacks that increase bite damage; at three stacks, the bite becomes a stronger Surging Bite. Her burst fires a tracking Hydro missile based on Max HP.

Mualani GUIDE

Understand Mualani

Useful when…

  • Use her skill to surf, move on water or liquid Phlogiston, and deal Nightsoul-aligned Hydro damage with converted normal attacks.
  • Build three Wave Momentum stacks before a Sharky’s Bite to trigger the stronger Sharky’s Surging Bite.
  • Use marked targets to launch Shark Missiles at multiple nearby marked opponents, keeping in mind the damage reduction against multiple targets.
  • Use her burst for a tracking AoE Hydro hit that scales with Max HP.
  • Use her exploration passive to reveal nearby Natlan-specific resources on the mini-map in areas with Phlogiston Mechanics.

Surf state and attack conditions

Surfshark Wavebreaker grants 60 Nightsoul points and puts Mualani into Nightsoul’s Blessing. While surfing, she moves faster, has increased interruption resistance, can move on water and liquid Phlogiston, and takes no damage from liquid Phlogiston. Her normal attacks become Sharky’s Bites, which deal Nightsoul-aligned Hydro damage based on Max HP and count as normal-attack damage; she can use them in mid-air. Contact with an opponent marks it as Prey and gives one Wave Momentum stack, up to three. The same opponent can grant a stack once every 0.7 seconds. Each stack raises Sharky’s Bite damage; at three stacks the bite becomes a Sharky’s Surging Bite, gains additional damage, and clears the stacks when it hits. Hitting a marked opponent with a bite removes that mark and fires Shark Missiles at up to five nearby marked opponents, then clears their marks. When multiple opponents are targeted by the bite and missiles, damage decreases, down to 72% of the original when three opponents are targeted. Her burst, Boomsharka-laka, fires a tracking Super Shark Missile that deals AoE Hydro damage based on Max HP. These attacks make the skill state and its contact-based buildup central to her damage pattern.

Keeping the state going and using its bonuses

The surf state ends when Nightsoul points run out or when the skill is used again. A Surging Bite hit can generate a nearby Puffer; picking it up restores 20 Nightsoul points, up to two Puffers during one Nightsoul’s Blessing. In Natlan, after Nightsoul points are depleted, Mualani can consume Phlogiston to maintain the state. Her Nightsoul Transmission can start the state with 40 points when switching to her from certain movement situations, but only in areas with Phlogiston Mechanics and once every 10 seconds for the team. Moving on water or liquid Phlogiston consumes Nightsoul points or Phlogiston more slowly: 75% less in Natlan and 35% less outside it. Nightsoul Bursts from nearby party members build Wavechaser’s Exploits, up to three stacks, lasting 20 seconds. Her burst clears those stacks and gains a Max-HP-based damage increase for each stack. This can be useful when the party can trigger those bursts before she uses her burst; it is separate from the Wave Momentum stacks used for Sharky’s Bites.

Improvement priorities

Her skill is the defining track because it supplies Nightsoul’s Blessing and the Sharky’s Bite attacks that scale with Max HP. Consider raising the burst track when you use Boomsharka-laka, which also scales with Max HP. Normal-attack investment is relevant to her transformed bites because they are explicitly considered normal-attack damage; the basic three-hit catalyst sequence is a separate attack description. The three combat tracks reach level 10, and the listed final upgrade examples require substantial Mora and materials plus a Crown of Insight. Ascension is a separate track with its own material costs. Prioritize according to how often you use her surf attacks and burst rather than assuming all tracks have equal value.

Limitations and common mistakes

Mualani’s main skill damage depends on Max HP, and the strongest bite requires building three Wave Momentum stacks through contact. A mark is consumed by the bite and its missiles, so one attack does not preserve marked targets for repeated missiles. Multi-target damage is reduced, reaching 72% of the original per-hit damage when three opponents are targeted. The skill state ends when its points are depleted unless a Puffer restores points or Natlan Phlogiston can sustain it. Do not confuse Wave Momentum, which strengthens Sharky’s Bites, with Wavechaser’s Exploits, which strengthen her burst after nearby party members trigger Nightsoul Bursts. Her charged attack is a separate stamina-costing Pufferball attack, not the surf-state bite.

Limitations and tradeoffs

  • Her skill’s strongest attack requires building stacks by contacting opponents, so it depends on staying in the surf state and engaging targets.
  • Her marked-target missiles can hit several enemies, but damage decreases when multiple opponents are targeted.
  • Her Nightsoul and Phlogiston movement benefits are stronger in Natlan, while outside Natlan the water-movement consumption reduction is smaller.

Common mistakes to avoid

  • Using Sharky’s Bite before building three Wave Momentum stacks when aiming for the Surging Bite.
  • Confusing Wave Momentum stacks for bites with Wavechaser’s Exploits stacks for her burst.
  • Expecting a marked target to stay marked after a Sharky’s Bite; the hit clears its mark.
  • Overlooking the multi-target damage reduction when bites and missiles hit several opponents.

Surfshark Wavebreaker · Elemental skill

Combining her mastery of speed and the waves and water, Mualani can surf anytime, anywhere.
After using this skill, Mualani will gain 60 Nightsoul points and enter the Nightsoul's Blessing state.

Nightsoul's Blessing: Mualani
Continuously consume Nightsoul points. When they are depleted or when the skill is used again, Mualani's Nightsoul's Blessing will end. The state itself has the following traits:
·Mualani mounts her Sharky Surfboard, increasing Mualani's Movement SPD and interruption resistance. Mualani can move on water and liquid Phlogiston while this state is active, and she will take no DMG from the latter.
·Normal Attacks will be converted to Sharky's Bites, dealing Nightsoul-aligned Hydro DMG based on Mualani's Max HP. Sharky's Bites can be used in mid-air. DMG dealt this way is considered Normal Attack DMG.
·When she makes contact with opponents in this state, Mualani applies "Marked as Prey" to them and gains 1 Wave Momentum stack. Max 3 stacks. 1 stack can be gained from the same opponent every 0.7s.

Wave Momentum and Marked as Prey
When Mualani uses Sharky's Bite, her DMG dealt increases based on Wave Momentum stacks. When she has 3 stacks, Sharky's Bite will be converted to Sharky's Surging Bite, further increasing her DMG and removing all her stacks when hitting an opponent.
When Sharky's Bite hits an opponent Marked as Prey, that mark will be removed, and she will fire Shark Missiles at up to 5 nearby opponents Marked as Prey, dealing DMG to them equal to this Sharky's Bite instance and clearing their Marks. If more than 1 opponent is the target of Sharky's Bite and Shark Missiles, the DMG dealt will decrease, decreasing at most to 72% of the original DMG when 3 opponents are targeted.

When Sharky's Surging Bite hits an opponent, a Puffer will be generated nearby. Mualani will restore 20 Nightsoul points when she picks up a Puffer. Only 2 such Puffers can be created in this way during a single instance of being in Nightsoul's Blessing.

Natlan's Greatest Guide

After a nearby party member triggers a Nightsoul Burst, Mualani will gain 1 stack of Wavechaser's Exploits, which lasts for 20s. Max 3 stacks. When she uses Boomsharka-laka, Mualani will clear all Wavechaser's Exploits stacks and increase the DMG of this Boomsharka-laka by 15%/30%/45% of her Max HP based on the number of stacks cleared.

Night Realm's Gift: Crests and Troughs

After her Nightsoul points are depleted, Mualani will switch to consuming Phlogiston to maintain her Nightsoul's Blessing.
While in an area with Phlogiston Mechanics within Natlan, she can use Nightsoul Transmission: Mualani. When the active character is currently sprinting, swimming, in a movement mode caused by certain Talents, or at a certain height in the air, the following will trigger when switching to Mualani: Mualani will enter the Nightsoul's Blessing state and gain 40 Nightsoul points. Nightsoul Transmission can be triggered once every 10s by your own team.

Additionally, Mualani's Nightsoul point or Phlogiston consumption while moving on water and Liquid Phlogiston during Nightsoul's Blessing is decreased by 75% while in Natlan, and her Nightsoul point consumption is decreased by 35% while doing the same outside Natlan.

The Trick Is to Keep Smiling!

While in an area with Phlogiston Mechanics within Natlan, 15 Phlogiston will be restored when interacting with some harvestable items. Additionally, the location of nearby resources unique to Natlan will appear on your mini-map.
