People of the Springs · Guide
A cheerful guide from the People of the Springs. Mualani is a 5-star Hydro Catalyst on-field HP-scaling DPS whose skill puts her on a surfboard-style Nightsoul state for shark / bite damage — she drives Vaporize, she does not play like Xingqiu.
Player guidance last verified: July 2026 · Constellation: Phoca Neomonachus
Strengths
- High HP-scaling Hydro DPS with satisfying surf combat loop
- Excellent Vaporize carry when Pyro application is stable
- Natlan Nightsoul synergy with Obsidian Codex and Scroll partners
- Strong exploration mobility on water and Natlan terrain
- Clear talent priority and build identity (HP + Crit + Hydro)
- Does not need ATK% sands like classic ATK catalysts
Weaknesses
- Needs a reliable Pyro applicator who doesn’t steal too much field time
- Bite / shark stacks have a rhythm — misplays tank DPS hard
- ATK-focused weapons and artifacts are usually wrong
- Less flexible than off-field Hydro supports in double-Hydro cores
- Wants dedicated on-field time as the driver
Kit Role Summary
HP-scaling Hydro surf DPS
Mualani’s Elemental Skill enters a Nightsoul surfing state. She marks enemies and deals chunky Hydro damage through bite / shark mechanics that scale primarily with Max HP. Her Burst is a secondary nuke / utility tool. She is an on-field Vaporize driver.
Talent priority (practical)
- Elemental Skill — most of her surfing DPS
- Elemental Burst — secondary nuke
- Normal Attack — last for standard play
Pro tip
Learn the mark → bite cadence before investing crowns. Perfect artifacts on a broken rotation lose to mid artifacts on a clean surf cycle.
