GitHub PR #386 by @leiming2333 (this commit is substantially the PR: its blizzard particles and flash). The official
blizzard blows bottom-up (the owner's confirmation of 2026-10-08; community report 「谢拉格的效果特性不明显，暴风雪应该
从下向上刮」): snowflakes rise off the bottom edge on a crosswind (48, low 22; were 26 drifting down), 10 gust streaks
(low 4) race up through the field, and the cold flash goes from 0.35 / 0.8 s to 0.45 / 1 s. Counts, speeds and lives
are marked [ASSUMED] (a visual choice).
Added on top of the PR: the same 'chill' fx is also the coldWind of 灵知 S3 (失温症, at its start) and of 麦哲伦 S1's
pulse (every 3 s — 248 in one golden battle); the PR turned every one of them into the full-screen blizzard. Only the
bond's field-wide wind (the device emits no anchor unit) gets it now; an operator's own coldWind (`id` = the unit)
keeps the light flurry and the softer flash it had.
Tests: test/render/fxchill.test.js (2; the gust case fails on the parent). Display only: golden unchanged.
The 赤霄·天喟 wave is a kit-managed probe (it turns corners and lives as long as the skill), not a snapshot
projectile, and the sim emitted one `dash` at the cast and a `slash` per hit — nothing along the way, so the client
drew no wave. op-chen3.js now emits fx('chen3Wave', { x, y, fromX, fromY, dr, dc, id }) every WAVE_FX_EVERY (0.12 s;
4 ticks), the trail restarting at a corner; render/fx registers chen3Wave → 'qi' (pt: drawn at the event, never on
her) and draws a streak plus a crescent head turned the way it travels. The look is a procedural stand-in, not the
official particle prefab.
Substantially @Convey123's code (PR #382), authored as theirs. Changed on review: the head is projected after
streak() — streak() reuses the effect system's projection scratch, so the PR drew the crescent on the trail's start,
one event behind the wave — and the trail, head and heading share one height; an unused test variable dropped.
Golden: diy-073 (5_diy*=chen3 S3 in two slots) events.fx 508 → 1558, fx.chen3Wave → 1050; diy-074 (6_diy*=chen3 S3)
events.fx 272 → 872, fx.chen3Wave → 600. HP, kills, damage, hooks and snapshot hashes unchanged: battle.fx only
records an event.
Tests: test/content/op_chen3.test.js (+1: the events, their cadence, id, direction, trail start, silence after the
skill) 12/12; test/render/fxchen3wave.test.js (new, 6: the archetype, drawn at the wave not at her, the head on the
wave and turned with it, a sweep joining into one trail, junk input, nothing left after) 6/6; boardart 15/15.
Seen (community report 「蕾缪安3技能范围里没人好像会自动结束」, relayed by the owner): with S3 locking, the locked enemy
killed or walking out of her range and nobody else in it, the skill ended at the next lock tick — the shells fell at
once and the bullets left were thrown away (repro on 0255afd: 3 of 5 bullets lost; a walker leaving her range, 1 lost).
Cause: chess_char_6_01-lemuen.js:169 `if (!e) { if (m.lemLocks.length) skill.end('ammo'); return; }`, there since the
initial import with no decision behind it.
Official: 「攻击装有5发弹药，打完后结束（可随时停止技能）」 — an ammo skill ends when its bullets are spent or the player
stops it; PRTS 卫戍协议/帮助 技能操作 「通常不会自动关闭技能」 (only 玛露希尔's 召唤使魔 is closed automatically); the client
(charpack char_4193_lemuen, buff_template_data lemuen_s_3): the S3 lock is an attack that needs a target and the skill
buff switches to the bombardment mode on ON_BUFF_FINISH only.
Now: with nothing to lock the skill waits (bullets and locks kept, the marks following their enemies or staying where
they left), its lock ready, so the next enemy in range (or 通缉) is locked on the next tick; it ends when the bullets are
spent and the shells fall on every mark in lock order as before. The S3 'lock' fx carry `hold`: render/fx/locks.js keeps
those reticles while the shooter's skill bit (UF.SKILL) is on and starts their LOCK_T at the skill's end (they faded 5 s
into a wait otherwise); S2's aim lock keeps its timeout.
Golden — traced on both trees (SkillRuntime start / end, the round's fields, the carried SP); in each the first
divergence is an S3 the parent ended with bullets left and nothing in her range:
- roster-018: the elite 蕾缪安's S3 of 7.63 s ended at 9.63 s with 2 of 6 bullets left; now the 6th goes at 12.00 s
(first differing snapshot window 0–10 s).
- boss-boss_3-pair: her S3 of 27.8 s ended at 30.3 s with 4 of 9 left; now all 9 by 34.43 s (window 30–40 s); the boss
now falls at 199.53 s instead of the 200 s cap.
- coop2-NORMAL-14-standins: ai_0's 蕾缪安 in round 11 ended S3 at 17.2 s (6 of 8 left) and 77.97 s (7 of 9); now she
spends them, enters the 联防 with 25.96 SP instead of 10.27, casts S3 there and kills one more of h_0's leaked enemies:
h_0 loses 1 LP less (rounds 11–12 LP 18 → 19, 8 → 9; lpLost 30 → 29; ai_0 kills +1).
bonds, standins, diy unchanged.
Tests: test/sim/feedback5-lemuen-s3-wait.test.js (3; the killed target and the walker who leaves fail on the parent),
test/render/fxproj.test.js +1 (a held lock waits while the skill bit is on; fails on the parent renderer).
Docs: CHANGELOG 0.2.0 规则（按官方）, docs/history/0.2.0.md §25.22.8 (also notes, unchanged: S2 spends a bullet on every
normal attack where PRTS says only the 通缉 snipe does — left to the owner).
Cause: 引星棘刺 S2's drifting alchemy unit is re-sent every second (position and radius change) and the client drew each
event as a new additive zone lasting the rest of the unit's life — up to twelve layers on one spot; overlapping units
(锡人's charges, several alchemists) added up the same way (render/fx/zones.js: disc alpha 0.28, edge 0.75, ADD blend).
Now: the sim fx carries `key` (kits/ops/chess_char_5_15-thorn2.js) and zones.js updates the zone under that key in place;
zoneAlpha draws a persistent area (> 3 real s) at 0.16 / 0.5 and ÷ √n among the n persistent areas overlapping it (centres
closer than ¾ of their radii summed); short bursts and telegraphs unchanged.
Golden: unchanged (fx events are counted by kind; the snapshots do not carry fx).
Tests: test/render/feedback5-zone-stack.test.js (3, fail on the parent).
public/js/render/fx.js becomes a re-export barrel. Speeds, camera heights, fonts, the kind table and the shared tunables move verbatim into public/js/render/fx/*.js. FxSystem keeps its constructor, clear, update, counts and destroy; the other methods move verbatim into container classes installed on FxSystem.prototype in source order. simSpeeds and fontsReady each stay one instance. The dynamic import of /sim/constants.js stays next to setSimProjectileSpeeds.
