And for my next trick...
This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.
A class MOD that reduces the number of Sleight of Hand charges, but when you kill an enemy with a Card, charges are restored and it resets up to Action Skill Duration. As long as you keep killing with Cards, you can keep Action Skill running, a rotation-type card for C4SH.
🧩 Red text source The standard line a magician says when moving to the next act “And for my next trick…”. The C4SH Card/Cheat (Sleight of Hand = magic tricks / dexterity) theme and “trick” are linked. There is no primary source citing a specific work (stock phrase) = the external source is (unverified).
What kind of class MOD? (Beginner’s perspective)
- C4SH (Rogue) exclusive Legendary class MOD
- Theme is Sleight of Hand (Card-throwing AS) rotation
- Sleight of Hand charge count decreases (drawback)
- Instead, when you kill an enemy with a Card, Charge +2 = replenished each time you kill with a Card
- At the same time Action Skill Duration resets = you can maintain Action Skill indefinitely
- Exclusive status +70% Action Skill Damage (Action Skill damage greatly increased) = the Card’s own firepower skyrockets = core of AS-focused build
Unique Effects (Mechanics)
Exclusive status
+N%is a Lv-dependent reference value (2026-08-06 added) The+N%below originates from Lootlemon / MentalMars. In-game, the exclusive status numbers change with Lv (what is fixed is only the status type, not the numbers).
- Measured: duration and damage types are Lv45 = +41% / Lv47 = +43%. Other MODs / other VH have the same value if same Lv (not dependent on individual roll or prefix) = provisional formula
value% = Lv − 4- With this formula, the Web’s
+45%is written as a fixed value equivalent to Lv49- ⚠️ Whether numbers like
+23%/+60%from other categories follow this formula is (unverified) (CD speed category may be Lv-independent with +23% at Lv45/47)
Rounder: Sleight of Hand charge reduction. Card kill with Charge +2 & Action Skill Duration reset.
- In-game: Sleight of Hand charge reduction. Card kill gives Charge +2 & Action Skill Duration reset
- Web (Lootlemon): Sleight of Hand gains Reduced Charges. Whenever C4SH kills an enemy with a Card, he gains 2 Charges and resets his Action Skill Duration. Always comes with the Stat: +70% Action Skill Damage
- Exclusive status +70% Action Skill Damage (Action Skill damage)
- ※Skill bonuses (+N) and accompanying stats differ per individual (= selection point).
- Weakness: The benefit assumes Sleight of Hand + Card kill. Because of the charge reduction drawback, if you cannot get Card kills the rotation stops

Build Synergy
- Core of Sleight of Hand rotation build: Card kill replenishes Charge + Action Skill Duration reset = as long as you keep killing with Cards you can maintain Action Skill
- AS damage focus: Exclusive +70% Action Skill Damage makes the Card (AS) itself’s damage skyrocket = directly tied to AS-focused build
- Card kill prerequisite: To offset the charge reduction drawback, creating firepower and situations where you can finish with a Card is important
- ※The target skill that receives the grant differs per individual (= selection point).
Summary
- C4SH (Rogue) exclusive. Card kill recovers Charge & Action Skill Duration reset Sleight of Hand rotation specialization
- Exclusive +70% Action Skill Damage greatly increases AS damage
- The benefit assumes Sleight of Hand + Card kill = for AS-focused builds
- Obtained from Idolator Sol (Fortress Indomita)
