Luuk Herssen, the 5-star Spectro Gauntlet Resonator, goes live in Wuthering Waves on February 26, 2026, at 10:00 AM server time as the Phase 2 banner of Version 3.1. Because each server region operates on its own clock, the exact moment you can pull for him depends on where you play.
Quick answer: Luuk Herssen's banner begins February 26, 2026, at 10:00 AM local server time — that's 10:00 AM ET for America, 10:00 AM CET for Europe, and 10:00 AM SGT for Asia.
America server release: February 26, 2026, 10:00 AM ET (UTC-5)
Luuk Herssen Banner Duration and Featured 4-Stars
The "When Winter Thaws" banner runs from February 26 through March 18, 2026, covering the entire second half of Version 3.1. It shares the Phase 2 window with Galbrena's rerun banner, "From Ashes," so players who missed Galbrena earlier can grab her during the same period.
Three 4-star Resonators receive rate-ups on Luuk Herssen's banner: Sanhua (Glacio Sword), Lumi (Electro Broadblade), and Yuanwu (Electro Gauntlets). If you've been waiting to build Sanhua constellations for her powerful Basic Attack DMG buff on Outro Skill, this is a solid opportunity.

Who Is Luuk Herssen?
Dr. Luuk Herssen serves as the attending doctor and counselor at Startorch Academy. In combat, he's a Spectro-element Gauntlet user whose kit revolves around the Tune Strain mechanic and dealing heavy Basic Attack DMG while airborne. His Resonance Skill cycles through three forms of "Aureole of Execution," each inflicting Tune Strain – Shifting on targets and building stacks that power up his Resonance Liberation.
His Forte Circuit introduces the Aureate Judge state, which activates at full Ichor Flow and dramatically increases the damage multipliers on his Aureole of Execution skills. Managing Ichor Flow — earned through normal attacks, skill hits, and Intro Skill casts — is central to maximizing his output.
Early Build and Team Recommendations
Luuk Herssen's damage scales primarily off Basic Attack DMG, making the 5-piece Rite of Gilded Revelation Sonata Effect with a Twin Nova – Nebulous Cannon main Echo the expected go-to setup. His signature weapon, Daybreaker's Spine, synergizes directly with his kit, though the standard 3.x Gauntlet option Pulsation Bracer works as a solid alternative.
For teams, Mornye stands out as his best support partner since both characters respond to Tune Strain – Interfered, and Mornye boosts Off-Tune Buildup Rate along with broad damage amplification. Pairing him with Sanhua as a sub-DPS is particularly effective because her Outro Skill significantly buffs Basic Attack DMG with minimal field time. Shorekeeper can substitute for Mornye when you need more Crit stats, and Roccia can replace Sanhua if you prefer a different rotation style.
Pre-Farming Materials
If you want to max Luuk Herssen on day one, you can start collecting his ascension and Forte materials right now. His character ascension requires Exoswarm Pendants (all four tiers from normal enemies), Suncoveter's Reach from a world boss, Edelschnee gathered in the overworld, and 170,000 Shell Credits. Forte upgrades add Waveworn Shards from Forgery Challenges and Gold in Memory from a weekly boss, with a total Shell Credit cost of roughly 2,030,000.
With the Asia server launching first on the morning of February 26 and America following later that same day, most players worldwide will have access to Luuk Herssen within a 15-hour window. His banner runs through March 18, giving you three full weeks to decide whether the Frostlands' resident doctor earns a spot on your roster.
