Domain Expansion

Domain Expansions are barriers built from Cursed Energy and used as a trump card. Without countermeasures, a Domain is basically a guaranteed win.

Domain Types

Lethal

Built to harm or kill the target. Very hard to complete, and needs refinement even after.

Gojo’s Infinite Void · Sukuna’s Malevolent Shrine · Jogo’s Coffin of the Iron Mountain · Mahito’s Self-Embodiment of Perfection

Non-Lethal

Rare today. It doesn’t harm the target, so it gets a near-instant construction time.

Hakari’s Idle Death Gamble · Higuruma’s Deadly Sentencing

Incomplete Domain (IDE)

The infant stage of a Complete Domain: your Innate Domain brought into reality, without a barrier.

Perks

  • +5 Sub-Tiers to Strength, Speed and Defense
  • CT +3 Grades (max G1)
  • Simple Domains, HWB and other Anti-Domain measures don’t work against it
  • Can punch a hole in a Complete Domain (but can’t win the clash)
  • No CT burnout afterwards

How to get one

  • Train: earn Domain Upgrade Points and unlock the IDE upgrade. Slow.
  • Witness one: get caught inside a Complete or Incomplete Domain. Dangerous if it’s a Lethal Complete Domain. Good luck!

Complete Domain (DE)

The pinnacle of Jujutsu. Your CT is embedded in the barrier, so every CT attack has a Sure Hit effect: no amount of speed lets you dodge.

Requirements: Potential High+ · Intelligence Gifted · 1+ Black Flash · a maxed Incomplete Domain

  1. At the end of every RP, roll 1d20. On 15+, your next RP takes place in a Dream World: your Innate Domain.
  2. Search for your true self (it can look like anything you want). Roll 1d20 3 times, needing 17+.
  3. Fail: you wake up and must wait 2 RPs before trying again.
  4. Succeed: accept your true self, and your Complete Domain is ready.
