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)

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.
