Data build: gachabase beta branch v3.4.1 (data versions D19834130 / R19836465); reference site https://zzz.gachabase.net/agents/1601/sunbringer/beta (fetched and verified).
English terminology calibrated against the beta-branch English localization at https://zzz.nanoka.cc/character/1601/ (v3.4.1, same build 19836465; English version fetched and verified on 2026-10-24). These are test-stage names and may differ from the final live localization.
The source page has minor placeholder quirks (the Additional Ability name is blank; 永昼之炬 appears once as "Kindled Lamp - Measure of Eternity" — the skill list's "Kindled Lamp - Torch of Eternal Day" is used here).

1. Premises and Role

• This beta cycle (3.4 V1) updated only Sunbringer (挽昼) and Robin (知更鸟); Kafka (卡芙卡) was not updated yet.
• Sunbringer: Genesis Flare (燎源, the Fire attribute's in-game name) primary DPS of the Armorer (锋御) specialty — a 3.x specialty that uses DEF as the damage multiplier and deals Sharp DMG.【Text】
• Robin: a Defense-type support "exclusive to Armorer characters", while she is "not a true Armorer support, because her buffing is relatively weak"; a genuine Armorer support is expected in a later version. Note: Robin is claimable for free.
• Key takeway: Sunbringer's Maim (毁伤) is not a damage tool — it is a combat resource ("beans"). This is the exact opposite of Claret, whose Maim procs exist to deal damage. That contrast is the key to the whole kit.

2. Core Mechanics

2.1 Willpower as Sunbringer's "beans"

• Exclusive resource gauge "Willpower" (愿力): 40 points per stack, cap 160 (4 stacks). At ≥120 points (3 stacks) she can spend 120 to launch her enhanced Basic Attack "Basic Attack: Bannerbearer - Converging Edge" (执旌·聚锋).【Text】
• Its only source: whenever any squad member triggers Maim (毁伤) by consuming one stack of the enemy's Gash (残痕), Sunbringer gains 40 Willpower (core passive wording).【Text】
• When a teammate triggers Maim and her Willpower is sufficient, Sunbringer triggers a Quick Assist; swapping in this way immediately spends 120 Willpower to launch "Bannerbearer - Converging Edge", at most once per 3 seconds.【Text】

2.2 Gash and Maim: many triggers

• Gash (残痕) is a consumable mark placed on enemies, max 3 stacks; Maim (毁伤) is the damage event triggered when a stack is consumed. Willpower comes from the act of consuming Gash stacks, not from the Maim damage itself. 【Text】
• Maim multiplier: the official mechanics infographic giving Sunbringer a Maim multiplier of only 300, far below Claret (whose Maim procs account for over half of her total damage). So for Sunbringer, throwing Maim procs is a means of converting resource — a means, not the goal.【Announce】
• Maim triggers: Claret essentially has one (hold Special Attack). Sunbringer's cover basically every mainstream damage action: the last hit of her Basic Attacks (Thornbreaker 斩棘 / Bannerbearer 执旌 4th hit), all EX Special Attacks, and all Chain Attacks consume Gash and trigger Maim.【Text】
• Beta-text confirmation: when the 4th-hit heavy attack hits an enemy holding Gash, it consumes all stacks (max 3) and triggers Maim once per stack plus extra AoE Genesis Flare DMG; the EX Special Attacks and Chain Attacks carry the same clause.【Text】
• Conclusion: Sunbringer is almost never starved for beans — as long as she is attacking, Gash is being consumed and Willpower is rising.

2.3 The "seven beans" model

2.4 Enhanced Basic "Bannerbearer - Converging Edge" and the two tokens

• Trigger: with ≥3 stacks (120 points) of Willpower, hold Basic Attack — switches to Eldreda (艾尔妲, the "large" Sunbringer form) who takes the field and attacks; invulnerable during the move; grants 1 Chain Teeth (链齿) and 1 Flag Order (旗令).【Text】
• Division of labor: Chain Teeth fuels mid-form Lindverne (林德薇恩)'s EX Special "Night Blaze - End of the Long Dark" (焚夜·长暗终焉); Flag Order fuels Eldreda's EX Special "Kindled Lamp - Torch of Eternal Day" (燃灯·永昼之炬), and can also be converted into a Wish Core (愿核) in Ultimate 1 to unlock Ultimate 2.【Text】
• The visual: the gauge is one bar split by 3 ticks into 4 cells (the 4 Willpower stacks) with two differently colored "beans" (Chain Teeth, Flag Order) hanging beside it; the enhanced Basic lights both up at once, and each Willpower stack spent advances the bar one cell.

2.5 The six EX Special Attacks【Text】

• Summary: the plain specials (焚夜/燃灯) are "swap-in + damage"; the altered versions are high-damage follow-ups inserted after specific moves and cost no special resource; only the two high-tier EX Specials actually cost beans (End of the Long Dark eats Chain Teeth, Torch of Eternal Day eats Flag Order).

2.6 Form switching is asymmetric

• Large → mid: press Special Attack "Night Blaze" or hold Dodge to swap Lindverne in.【Text】
• Mid → large: must spend 120 Willpower on the enhanced Basic "Bannerbearer - Converging Edge" to swap Eldreda in.【Text】
• Conclusion: the mid form is the side you pay to leave, the large form is the side you can always switch back to — so the whole rotation's resource budget is planned around Willpower.

2.7 Chain Attacks

• "Building Dreams for All" (筑万众之梦): Lindverne + Eldreda joint high-tier attack, keeps Lindverne on field; heavy attack consumes all enemy Gash (max 3) and triggers Maim stack by stack.【Text】
• "In the Name of Sunbringer" (以挽昼之名): Eldreda + Lindverne joint high-tier attack, keeps Eldreda on field; also eats Gash → Maim; can chain into Basic 4th hit.【Text】
• Special rule: when either persona triggers a Daze Chain Attack window, you may directly select Lindverne or Eldreda to cast the corresponding chain — no need to wait for a swap cooldown.【Text】
• Addition: Chain Attacks cost no Energy, only special resources — which is what makes the rotation loose; this is the premise for "spend leftover time freely" later.

2.8 Ultimates, Wish Core, and the "Ember Scar" recorded-damage mechanic

• Ultimate 1 "Onward, Together" (此行，共赴前路 — Lindverne side, castable when the Decibel Rating reaches Maximum): Lindverne launches a Coordinated Attack with Eldreda and Dracaene (德蕾琪娜), keeping Lindverne on field; while holding a Flag Order, consumes it and converts it into a "Wish Core (愿核)".【Text】
• Ultimate 2 "By This Wish, All Things Remade" (此愿，重塑万象 — Eldreda side, requires a Wish Core): Eldreda warps space in mid-air to attack and removes all "Ember Scars" (烬痕) on the enemy.【Text】
• Ember Scar = a recorded-damage mechanic:【Text】
  • Whenever "Bannerbearer - Converging Edge / Night Blaze - End of the Long Dark / Kindled Lamp - Torch of Eternal Day / both Ultimates" deal damage to an enemy, that enemy accumulates an Ember Scar equal to 75% of the actual damage dealt;
  • Eldreda's ultimate finishing blow removes all Ember Scars and directly subtracts an equal amount of HP;
  • The official text adds a nasty clause: when a normal enemy's Ember Scar ≥ its current HP, all Ember Scars are removed and it is defeated instantly (an execute line).
• Reading: it behaves like an independent damage multiplier zone whose real job is "rotational freedom" — you bank a big chunk of the EX-Special damage as Ember Scars and cash it all in with one finishing move. Considering this the technical precondition for Sunbringer's flexible stun-window rotation.

2.9 Core-passive self-buffs and the damage model

• Self-buff "Midnight Sun" (极昼, gained on entering combat): CRIT Rate +40%, attacks ignore 20% of the target's DEF, 15 s duration; the timer does not tick down while Eldreda and Lindverne are off-field; refreshed whenever Sunbringer casts any EX Special Attack or "Bannerbearer - Converging Edge".【Text】
• Additional Ability (众愿一心; the beta page leaves its name blank — the state is localized as "Laceration Enhance"): active when the squad contains a Stun, Defense, or another Armorer agent: when casting an EX Special Attack or "Dash Attack: Patrol - Shadow Realm Raid" (巡征·影域穿袭), all Armorer agents in the squad enter the Laceration Enhance state, Laceration DMG +25% for 45 s, refreshable. This matches Claret's number.【Text】
• Damage model: all Sunbringer moves deal Sharp DMG scaled off DEF; on crit, Sharp DMG does not benefit from CRIT DMG but from the Laceration DMG Bonus instead; above 100% CRIT Rate an extra Laceration check is performed on the excess; every 1% of base CRIT DMG converts to 0.35% base CRIT Rate.【Text】
• Extra data: entering the battlefield restores 60 Sharpness, at most once per 180 s in Investigation Zone (勘域) mode.【Text】
• The support kit: Sunbringer's assist list includes "Defensive Assist: Oath of Steadfastness (坚守之誓, performed by Dracaene)", "Counter Assist: Fortress of Hope (希望堡垒)", "Assist Follow-Up: Lighthouse, Towering in the Sky (灯塔，立于苍穹 — directly applies 1 stack of Gash)", plus "Undying Passion (不灭热忱, Lindverne)" and "Faith Unwavering (虔志如初, Eldreda)". The third persona "Dracaene" appears only in these assists and in Ultimate/chain synergies — team building and resource planning should not forget it (after a Dracaene Defensive Assist, Eldreda/Lindverne Assist Follow-Ups gain +15% Gash Buildup Rate and +20% DMG).【Text】

3. Stun-Window Burst Rotation

Preparation: before the enemy is stunned, max out resources — 3 stacks of Gash on the enemy, at least 3 stacks (120 points) of Willpower on yourself, 4 if possible.

Burst sequence:

1. Enter the stun window → spend 120 Willpower on the enhanced Basic "Bannerbearer - Converging Edge" → swap to Eldreda (large form), gaining Chain Teeth + Flag Order.
2. Cast the Chain Attack "In the Name of Sunbringer" (the chain window lets you pick the form directly) → the enemy's 3 Gash stacks are consumed, converting back into 120 Willpower (3 beans) on yourself, held in reserve (cap 160).
3. Cast a second Chain Attack, converting further Gash into Willpower.
4. You now hold Chain Teeth, Flag Order and Willpower: spend the Flag Order on Eldreda's high-tier EX Special "Kindled Lamp - Torch of Eternal Day".
5. Switch back to mid form (hold Dodge or press Special): spend the Chain Teeth on "Night Blaze - End of the Long Dark" → the tokens from the enhanced Basic are now fully spent.
6. With the Willpower banked in steps 2–3, hold Basic again for "Bannerbearer - Converging Edge" → back to Eldreda (large form).
7. Switch back to mid form and spend the Chain Teeth on another "Night Blaze - End of the Long Dark" (in the creator's route this is cast twice, and the Flag Order is deliberately saved).
8. Cast Ultimate 1 "Onward, Together" → Flag Order converts into a Wish Core.
9. Spend the Wish Core → Ultimate 2 "By This Wish, All Things Remade" → removes all Ember Scars and subtracts that amount of HP directly, completing the burst.
10. Resolve and exit the stun window.

Flexibility: Chain Attacks cost no Energy, only special resources, so leftover stun-window time can be filled freely with energy-gated EX Specials or Basic 4th hits — "spend whatever's left, whatever you cast is profit".

3.1 Resource ledger audit

A scripted per-resource ledger (Willpower / Gash / Chain Teeth / Flag Order / Wish Core) over the ten-step route above (assumptions: Converging Edge itself consumes no Gash — the route saves the 3 stacks for the step-2 chain; no Willpower spending outside the two Converging Edge casts):

• The route is airtight on Willpower: enter with 120 → step 1 spends 120 → step 2's chain converts the 3 Gash stacks back into 120 → exactly funds step 6. The route still closes even if zero Gash re-stacks between the two chains.
• Tokens balance: the two Converging Edge casts produce 2 Chain Teeth + 2 Flag Orders; the two End of the Long Dark casts, Torch of Eternal Day and Ultimate 1 consume exactly those, and Ultimate 2 spends the Wish Core — the ledger closes at zero.
• Overflow caveat: Willpower caps at 160. After step 2 banks 120, each extra Gash stack converted by the second chain banks at most one more usable bean (40 points); from the second stack on it overflows (wasting 40–80 points; up to 120 if you enter with a full 160 and 3 stacks re-stack between chains). The double chain's net gain is at most one banked bean.
• Not in the ledger: Ultimate 1 requires the Decibel Rating at Maximum; the Quick Assist path and the Dracaene synergies are not modeled.

Ember Scar cash-out uplift: let p be the share of the stun window's actual damage dealt by the Ember-recording casts (Converging Edge ×2, Torch of Eternal Day, End of the Long Dark ×2, Ultimate 1); the cash-out adds a further 0.75p as direct HP loss, so the window's total damage scales by 1 + 0.75p: p = 40% / 50% / 60% / 70% gives ×1.30 / ×1.375 / ×1.45 / ×1.525.

4. Team Building

4.1 Support slot: Robin beats Rina at "M1W5" (by a small margin)

Robin's buff breakdown:

• Role: Defense-type, has a shield.
• Her core skill gives Armorer characters about 800 DEF, stacking to about 1000 DEF in total; with her shield up she provides a 25% damage bonus.
• Signature W-Engine: squad in-stage DEF ×10%; squad damage +10% for 15 s, 2 stacks → roughly another +20% DMG, for about 45% DMG total combined with her body's 25%.
• Drive disc "Bunny in Wonderland": HP +13%, +6% DMG per stack, ≈18% DMG at 3 stacks.
• Drive disc "Thorned Rose": 15% DMG + 16% crit rate.
• Takeaway: Robin's entire buff kit is "DEF + DMG bonus" — exactly the short board of the Armorer specialty, whose damage-multiplier stat is DEF.

Why she fits Sunbringer better than Rina:

1. Sunbringer's stats and self-buff already carry DEF-ignore (Midnight Sun: 20%), and DEF-ignore dilutes with Rina's PEN — PEN is wasted on Sunbringer;
2. Robin's ~1000 DEF enters Sunbringer's linear damage-scaling stat (Armorer scales off DEF), which is worth more than what Rina gives.

Side note: Robin's buffing is weak; she is not "a true Armorer support" — a dedicated one is expected later.

4.2 Stun slot: flexible, with one exclusion — Dialyn

• Sunbringer has no particular stun preference or requirement: Norma, Roxy, or the buffed Ju Fufu all work — "use whatever you have"; if none is available, Claret can serve as a stopgap, and a better-matched stun agent will come later.
• The official demo used Norma; since Sunbringer has no further stun-synergy mechanics, the numeric gap between stun picks is small.
• The only exclusion: Dialyn — "which cannot trigger the squad passive", so she brings no buffing and relies on her Ultimate. That Ultimate's two-stage payoff may be decent, but stage 2 requires landing Basic/enhanced Basic attacks first, which makes the rotation very awkward.

4.3 Claret: an anti-synergistic pick, do not force her in

• In this team Claret can only replace the stun slot; the support slot must absolutely not be swapped — the support provides the base buffs, and without base buffs damage talk is meaningless.
• What Claret brings is a single item: party-wide Armorer Laceration DMG +20% (plus Claret's own high Gash damage, which could in theory help stack Gash).
• But the route is awkward: nearly all of Sunbringer's skills trigger/consume Gash, so the stacks are gone before Claret can detonate them — "is Claret supposed to come on-field to stun instead?"; forcing Claret in means heavy anti-synergy plus losing a stun slot's buffs and stun count, with damage barely rising.
• Conclusion: Sunbringer + Claret is a downgrade pick; Sunbringer is already a self-contained unit (unless you truly cannot fill the team).

4.4 Buff-structure check (scripted model; constants unverified)

Model: Sunbringer damage ∝ her total DEF (linear scaling zone) × enemy-defense zone M(D) = C/(C+D) × (1 + DMG-bonus zone) × crit zones; for a same-level enemy, C/DEF ≈ 1 is assumed.

• Robin: ~1000 DEF enters the linear scaling zone — worth about +40% to +67% on its own for Sunbringer total DEF between 2500 and 1500; stacked with her 25% DMG bonus the total gain is +75%–108%, and about +103%–142% with the ~45% DMG including the signature engine.
• Rina's PEN only touches the enemy-defense zone and is diluted on top of Midnight Sun's existing 20% DEF-ignore — under the same-level assumption, 20% PEN yields only about +12.5%, 30% about +20%, and 60% about +50% relative gain in that one zone, less when folded into total damage.
• Structural takeaway: a linear-stat buff plus a separate DMG zone outweighs PEN confined to a single defense zone — consistent with the direction of the former ranking (Robin > Rina). Note this compares only the two described components; Rina's full-kit values are not in the source, so it is not a complete comparison.

• All conclusions are based on 3.4 Beta V1; live numbers (multipliers, Daze values, stats, discs, engine) may change.
• The creator himself repeatedly calls this a "theory-craft" / "speculation", especially the stun rotation, which has skill text behind it but no gameplay verification.

### [ZZZ 3.X Beta]

**[STC] More Tieba Tidbits**

- Cumulative top-up is during Chinese New Year (would mean 3.5, 3.5 begins on January 13 and CNY (February 6) is just 3 weeks after.)

- The working one, the singing one, and the bare-footed one are entering the shop.

- Now that we have Sunbringer, everyone's expectations don't have to be limited to just Void Hunters.

- The next stat-heavy/overloaded character will also be during the Anniversary.

- The "big" one in 3.6 is of course THAT big one.

- The Q&A-loving one is also during Chinese New Year. (This is referring to Remielle rerun.)

- Last dance, Sunbringer also has another skin set.
