Core Goal: Maximize Hiyuki's Snow Rust stacks (3/3) via Glacio Chafe application for massive Glacio Bite/DoT damage amplification. Lucilla is Hiyuki's BiS sub-DPS because she enables the full 3-stack potential that Lynae + Chisa cannot fully achieve alone. Full stacks unlock Glacio Bite amps, Crit DMG buffs, and peak Hiyuki damage output.

Chisa
Support / Buffs
Havoc Bane + team buffs

Alternatives if Missing Characters

ReplaceWithNotes
Chisa S1 Mornye or Shorekeeper Crit/ATK buffs, slight DPS loss; better if you have Hiyuki sequences
Chisa (F2P) Mornye / Shorekeeper Viable but lower ceiling than the premium comp
Lucilla Lynae Works pre-Lucilla but can't enable full 3-stack potential - Lucilla is strictly better for Glacio Chafe synergy

Rotation Steps

Target: ~30 seconds or less per cycle. Focus on swapping during outros and keeping Chafe uptime constant. Aim for 3 Snow Rust stacks active on Hiyuki at all times.

Why this order: funnels buffs to Hiyuki, keeps Glacio Chafe constant via Lucilla's Resonance Mode, and uses quick-swap to eliminate downtime. Practice dodging into Hiyuki's Iai strings in open world before tackling Tower of Adversity.

Key Decision Points

Pull Priority
Lucilla first
Highest priority for Hiyuki owners - enables the 3-stack ceiling no other support can achieve. Chisa next if missing, but skippable at high Hiyuki sequences.
Hiyuki Sequences
S1 then S3
S1 for quick power spike. S3 for team independence (less reliant on specific supports). Stop there unless going very deep on investment.
Rotation Complexity
Master outro timing first
If struggling with full rotation length, simplify to Chisa to Lucilla to Hiyuki swaps and focus on outro timing before perfect execution.
Echo/Weapon
Glacio and Chafe priority
Prioritize signature weapons. For Lucilla, prioritize echo sets that boost Glacio/Chafe application. Optimize substats for Crit and Glacio DMG.
