SILVERPALACE BUILD

Captain Kaboom Build

Updated 31 October 2026

Captain Kaboom is a Break Suppressor: build her for Break Exploit and Stun Buildup Bonus rather than CRIT, give her a Saviour Motive (The Bloodbath Mystery if you have it) and Cogs of the City Implements, and pair her with a DPS such as Rex or Cinderella to execute what she stuns. Beta data; Elementa can change it before launch.

Best Motives for Captain Kaboom

Only a Saviour Motive turns on its Motive Skill for Captain Kaboom; on any other Identity it is a stat stick (Motives system guide). Six are known.

  • The Bloodbath Mystery Motive

    The Bloodbath Mystery

    Our pick

    ★★★★★

    Highest Saviour ATK, 529 at Lv. 80 (fan-compiled). A free day-5 log-in reward in the Dichotomy beta (official notice). Skill not filmed yet.

  • The Would-Be Adults Mystery Motive

    The Would-Be Adults Mystery

    Weak fit

    ★★★★

    31.25% CRIT DMG, plus 24% ATK for 15s after Tactical Assault at Tier 1 (Shrike’s screen).

  • The Ivory Tower Mystery Motive

    The Ivory Tower Mystery

    ★★★★

    Featured on the CBT2 banner. 423 ATK at Lv. 80 (fan-compiled).

  • The Fine Stitches Mystery Motive

    The Fine Stitches Mystery

    ★★★★

    On the CBT2 rules panel. 423 ATK at Lv. 80 (fan-compiled).

  • The Bullet Mystery Motive

    The Bullet Mystery

    ★★★

    370 ATK at Lv. 80 (fan-compiled).

  • The Blade Wind Mystery Motive

    The Blade Wind Mystery

    ★★★

    Ultimate Charge Efficiency after a skill (银Khye’s screen).

Our pick, not a creator's: The Bloodbath Mystery, for its ATK. Be wary of CRIT DMG lines such as Would-Be Adults' 31.25%: Shrike's level-60 Captain Kaboom has a 5% CRIT Rate, so they rarely trigger.

Cogs of the City

Best

Break Exploit +60 (4 pieces). Above 200 Break Exploit, every Charged Attack gives the holder +25% Stun Buildup Bonus for 14s.

  • Non-Absorbent Towel, Cogs of the City Neck ImplementNon-Absorbent TowelNeck
  • Non-Turnable Wrench, Cogs of the City Secondary Weapon ImplementNon-Turnable WrenchSecondary Weapon
  • Non-Insulated Lunch Box, Cogs of the City Accessory ImplementNon-Insulated Lunch BoxAccessory

Why: Her Pressure spins are Charged Attacks, so the bonus is up almost all the time.

Alternative

Best Epiphany for Captain Kaboom

White Beast of the Deep Epiphany

White Beast of the Deep

Our pick

Break Exploit +120

+60 Break Exploit. Above 180 Break Exploit, each extra point gives 0.15% DMG Bonus, up to 30%.

Why: Its Break Exploit helps reach the 200 that Cogs of the City asks for, and pays back in damage.

Death of a Clerk Epiphany

Death of a Clerk

Alternative

ATK +24%

+10% Radiatio DMG. Dealing DMG gives a Fatal Shadow stack: +25% CRIT DMG for 10s, up to 5.

Why: Fan data ranks it first, but its CRIT DMG needs CRIT Rate she does not have: 5% at level 60 in Shrike’s footage.

The Epiphany is the fifth gear slot, one per character. Duplicates raise its stats, never its effect. Effects are fan-compiled from the game files.

Captain Kaboom stats

Shrike, 2:54. Captain Kaboom at level 60 still has the 5.00% base CRIT Rate. A Break Suppressor is not built for crit.

For Break Suppressors, fan-compiled data names Break Exploit and Stun Buildup Bonus (character stats guide). Aim for 200 Break Exploit, the Cogs of the City threshold. Shrike's level-60 Captain Kaboom reads:

Our order, not a creator's. In the fan-compiled data her Basic Attack node holds the Charged and Enhanced Charged Attacks, so that is where her Pressure spins, and her stun, get stronger. No creator has filmed her at high skill levels yet.

What every level costs is on the Captain Kaboom materials page.

Captain Kaboom Psyches

  1. Psyche ISpinotrode Mender. Her Charged Attacks parry incoming hits on their own, and each hit raises that enemy’s Coup de Grâce DMG by 0.6%.
  2. Psyche IICity Worker Bee. Tactical Assault fills her Pressure, and Charged Attacks add 1% Radiatio DMG on hit.
  3. Psyche IIIBeyond City Lights. +20% Ultimate DMG.
  4. Psyche IVSmall Stature, Big Spirit. After her skill, +15% Radiatio DMG for 10s.
  5. Psyche VRoot Cause of the Fault. After she Executes an enemy, the whole team gets +20% ATK for 40s.
  6. Psyche VIHome Is Where the Kaboom Is. Wider Charged Attacks that pull enemies together and ignore 10% DEF; her Coup de Grâce adds 10% Radiatio DMG.

Each Psyche costs one more copy of Captain Kaboom. Effects are fan-compiled from the game files. Our reading: Psyche II (full Pressure on swap-in) and Psyche V (a team ATK buff after each Execution) change how she plays the most. The character progression guide explains the system.

Is Captain Kaboom good? Tystra’s verdict

Captain Kaboom winding up her Explosive Bear ultimate in Silver Palace, with the tutorial note that it deals massive damage
7:05. Explosive Bear ends Tystra’s demo, a few seconds before his verdict. The tutorial says only that it “deals massive DMG to enemies”.

He ends the demo with the ultimate at 7:05: “Kaboom. And that’s why they call them Captain Kaboom.”

Our tier list does not rank Captain Kaboom yet. Tystra’s verdict at 7:33 is “a great break suppressor”, “a little bit slow” on attacks, but with damage and the ability to break the gauge “very quickly”. He gives her “a thumbs up” and says she “might be worth investing in”. That is his opinion on beta footage.

How to get her at launch is not known. Tystra had all 14 beta characters on his test account, which says nothing about banners. The gacha guide has the beta pull rules.

What is still unknown about Captain Kaboom

  • Final numbers. The 90 Pressure, 45 from the skill and +15% ATK are beta values. Tystra says himself at 1:30 that “kits are subject to change”.
  • The passive in action. Repair Toolbox was not awakened on his account.
  • Retrace changes. The Dichotomy: Retrace build may have changed her kit, but its NDA keeps that private for now.
  • Launch availability. Silver Palace launches worldwide on 14 December 2026 (UTC+8), announced on 31 October 2026. No launch banner plan has been announced.
