Genshin Impact introduced Mualani through a drip marketing campaign, confirming she is a Natlan character, like Kachina, Kinich Mavuika, Xilonen, and Citlali. The detailed trailer for the Natlan region revealed that she is a Hydro user who rides a shark toy. While her rarity hasn’t been officially confirmed, leading leakers suggest that Mualani will be a five-star unit, similar to Kinich.
Recent leaks from Homdgcat have revealed that Mualani's kit and weapon will undergo some balance changes before her debut in Genshin Impact. According to the leaks, the cooldown of Sharky's Bite (elemental skill) will increase from 1.6 to 1.8 seconds. Her elemental burst will now deal damage equal to 105% of her max HP, up from 89%. Additionally, Mualani will generate a Puffer when Sharky's Surging Bite hits an enemy, but she will restore 15 fewer Nightsoul points when collecting a Puffer.
A mix of nerfs and buffs.
Mualani will restore eight energy (reduced from 15) when collecting a Puffer she has created. Additionally, her weapon will grant four Scorching Summer stacks, but this will now occur over 14 seconds (up from 10 seconds) after using her elemental skill. As early leaks from Homdgcat suggest, Mualani will undergo a mix of nerfs and buffs before her official release.
Genshin Impact's Mualani is a Catalyst user whose plunging attacks deal AoE Hydro damage. Her elemental burst launches a missile that tracks enemies and deals damage based on her max HP. While in the Nightsoul's Blessing state, she rides the Sharky Surfboard, gains a movement speed boost, and her basic attacks become shark bites. To upgrade Mualani, players will need Mark of the Binding Blessing, Varunada Lazurite Fragment, Warrior's Metal Whistle, Sprayfeather Gill, and Sentry’s Wooden Whistle.
