Here’s the most likely way to get Vow in Cursed Incremental : it appears to be a binding vow feature, and in related JJK incremental games those are usually unlocked through story progression and/or bought in the shop rather than rolled randomly.

Quick Scoop

  • In the game’s menu for the related Cursed Fate version, you can select binding vows from the menu, which suggests vows are a progression system you unlock and manage there.
  • A 2026 guide for Sorcerer Incremental says Binding Vows are unlockable through story and buyable in the shop , which strongly points to the same kind of progression loop in this genre.
  • The Cursed Incremental promo/codes page confirms the game has story arcs, missions, territory/restriction systems, and prestige , so vow-related unlocks are likely tied to those progression layers.

Practical steps

  1. Push the main story arcs forward as far as possible.
  2. Check the shop / cursed market / progression menu for a vow unlock or binding vow option.
  3. Complete missions and chapter rewards , since these games often hide key systems behind those milestones.
  4. If there’s a requirement like a special arc, rebirth, or rank, keep progressing until the vow entry appears.

What to look for in-game

  • A menu tab labeled Vow , Binding Vow , or Restriction.
  • A shop item that mentions binding vows , sacrifice , or permanent power.
  • Story/mission completion rewards that unlock new systems.

Best guess

If you want the shortest answer: keep progressing the story, then check the shop/menu for a binding vow unlock once you’ve advanced enough.

Note
