How to Get Sukuna's Mark, Open Shrine, and World Cutting Slash

What the passive changes

The live tooltip confirms +100% Shrine damage. Moves apply Sukuna Mark, which deals damage and fills a bar; a full bar unlocks World Cutting Slash. The passive also upgrades punches and gives Shrine an open domain. The source video additionally reports that regular ailments such as Water Prison stop activating, so ailment-focused equipment is a poor fit for this setup.

The official Trello documents Shrine and Sukuna synergy buffs, while the owner-provided live tooltip confirms the passive's current core effects.

Collect the three parts

The official Trello confirms Infinite Crate and the miniboss spelling Cursed Remanence. The transcript's “Cursed Remnant” is corrected here. Fractured Mark 1 has a confirmed 0.4% Infinite Crate rate. The exact chances for Fractured Mark 2 and 3 remain unknown, so no expected run count should be published.

The remaining source is King of Curses on Calamity, level 1,400. This awards Fractured Mark 2; easier difficulties should not be assumed to count. No unverified drop percentage or expected run count is published for any part.

Collect the three parts

“Use the required final difficulty; easier versions may not award the part.”

Exchange and use World Cutting Slash

Bring Fractured Mark 1, Fractured Mark 2, Fractured Mark 3, 3 Cursed Flesh, and 5,000,000 Yen to Passive Ability Exchange, whose name is confirmed by the official Trello. All five requirements are needed to craft Sukuna's Mark.

While Sukuna's Mark is equipped, moves apply its damaging mark and fill the passive bar. When the bar is full, World Cutting Slash becomes available. Exact tick timing, charge increments, move-specific behavior, and boss immunity are intentionally omitted because they are not shown in the confirmed tooltip.

Is it worth using?

For dedicated Shrine builds, the claimed damage and extra attack make the passive a priority. It is less compelling for Ten Shadows, Awakened Star Rage, or another technique because its main benefits are Shrine-specific. Compare identical gear and targets before making meta claims, and remove ailment-dependent equipment from the test.

Important warnings and common mistakes

• Use Cursed Remanence, the official spelling.
• Do not farm an easier boss difficulty for the final part.
• Do not invent unknown drop rates, timers, or level requirements; only Fractured Mark 1's 0.4% rate is confirmed.
• Do not keep an ailment-centered setup if the live passive disables it.
• Do not publish the two speech-transcribed codes without exact official confirmation.
