Glacio Chafe Team Guide: Hiyuki, Lucilla, Chisa

Glacio Chafe belongs to the family of Negative Status effects that define modern Wuthering Waves team-building, sitting alongside Aero Erosion, Spectro Frazzle, Fusion Burst, Havoc Bane and Electro Flare. Rather than a single hit, Chafe is a stacking debuff: applying Glacio damage builds stacks on the enemy, each stack reduces the target's Move Speed, and once the stack count hits its cap (10 by default), the target freezes solid and every stack clears at once.

• The archetype rewards a team that can apply the status quickly, refresh it before it falls off, and raise the stack ceiling so the team can bank more Move Speed reduction and control exactly when the freeze lands.
• That is exactly the division of labor a three-person Chafe team needs: one character applying and triggering, one topping up stacks, and one extending how high the stacks can go.

Verdict: Glacio Chafe is a stack-and-freeze mechanic, not a damage-detonation debuff, which is why it needs a dedicated three-person core rather than a single strong DPS.

Hiyuki is the top Glacio DPS built specifically around the Glacio Chafe status, and she is rated SS tier as a main-DPS. Her kit is built to rival the strongest meta teams in the game, combining self-buffing, area crowd control, and hard-hitting nuke attacks that scale off the Chafe stacks she herself helps stack up.

• Role: main DPS — she is the one converting stacked Chafe into real burst damage.
• Weapons: Frostburn is her signature pick, with Emerald of Genesis (the standard 5★ Sword) as the strongest non-signature option.
• Echo Sonata: 5-piece Wishes of Quiet Snowfall.

Because she brings her own AoE crowd control on top of a real nuke, Hiyuki does not need a separate CC unit in the slot — that frees the other two team slots entirely for buffing and stacking.

Lucilla is rated SS tier as a sub-DPS and is what makes this specific trio work — she is the best Glacio Chafe applicator-buffer in the game — including raising the max Chafe stack count from 10 to 30 — and her kit is flexible enough to instead run as an Echo Skill DMG amplifier on par with other top amplifiers when a team calls for it.

• Role: sub-DPS — applies and buffs the Chafe status and raises the stack ceiling, so Hiyuki's freeze windows land harder and more often.
• Weapons: Freeze Frame is her top pick, followed by Cosmic Ripples and Variation.
• Echo Sonata: 5-piece Wishes of Quiet Snowfall, matching Hiyuki's set for a shared team bonus.

Verdict: Lucilla completes the premium Glacio Chafe core alongside Hiyuki, and the pairing is strong enough to clear both single-target bosses and multi-wave endgame content with ease.

Chisa is rated SS tier as a support, and her value in this team is structural rather than about her own damage. She is a universal Negative-Status support whose kit shreds enemy DEF through her Havoc Bane application, softening the target for both Hiyuki's and Lucilla's Glacio hits.

• Role: support — DEF shred for the whole team via Havoc Bane, freeing Hiyuki and Lucilla to focus purely on applying and cashing in Chafe stacks.
• Echo Sonata: she runs 5-piece Rejuvenating Glow rather than Wishes of Quiet Snowfall, since her job is support stats and DEF shred, not adding her own Glacio damage.

She is best described as a luxury piece — the archetype functions without her, but the DEF shred is a genuine damage increase on top of what Hiyuki and Lucilla already produce together.

The team's shared Echo set is the 5-piece Wishes of Quiet Snowfall Sonata, worn by both Hiyuki and Lucilla — the two characters actually dealing and applying Glacio damage. Chisa runs Rejuvenating Glow instead, since her job is enabling the other two rather than contributing her own element damage.

• Running the same 5-piece set on both damage-dealing slots is what lets this trio stack a full team-wide Sonata bonus instead of splitting it.
• Patch 3.5 is adding a new Glacio support built around Glacio Chafe and an Energy Regen-to-team-ATK conversion, releasing in the patch's second phase and running the Song of Feathered Trace set rather than Wishes of Quiet Snowfall.

Verdict: Wishes of Quiet Snowfall is the confirmed best-in-slot Sonata for this archetype right now; Song of Feathered Trace is an emerging second branch tied to the incoming 3.5 support, worth watching once ratings settle rather than switching to pre-emptively.

What makes Hiyuki, Lucilla and Chisa stand out is that all three pieces are rated SS tier independently — this is not a case of one strong carry propped up by filler slots. Hiyuki brings the nuke and the AoE control, Lucilla brings both the applicator-buffer role most Chafe-adjacent kits lack and a much higher stack ceiling, and Chisa turns her DEF shred into extra free damage on top of that.

• Lucilla's dual-mode kit (Chafe applicator-buffer or Echo Skill amplifier) means the core does not go dead if endgame content ever favors a different sub-DPS role.
• Hiyuki's built-in crowd control means the team does not need to spend a slot on utility, unlike many other main-DPS-centric comps.
• The trio covers both major endgame benchmarks: single-target burst for Tower of Adversity and sustained, repeatable output for the multi-wave Whimpering Wastes format.

Verdict: SS/SS/SS across the board, with no dead slot and no missing role, is what earns this comp a place among the strongest teams currently rated.

There is no confirmed free 4★ substitute for this specific trio in the current data, since Hiyuki, Lucilla and Chisa are all 5★ Resonators. Where F2P players do have a real opening is on the weapon side of the build.

• At Union Level 45, every account unlocks a free standard 5★ weapon selector — and two of this team's best non-signature weapons are on that list: Emerald of Genesis (Hiyuki's Sword option) and Cosmic Ripples (Lucilla's Rectifier option).
• That means a F2P account can equip two of the three core weapons for this team at zero gacha cost, once Union Level 45 is reached, without needing to pull for signatures.

Verdict: the character trio itself has to be earned or pulled, but the Union Level 45 free selector covers meaningful weapon value for two of the three slots — grab Emerald of Genesis or Cosmic Ripples there rather than spending Astrite chasing a signature early.
