Vessel’s Ultimate in Jujutsu Shenanigans lasts about 1 minute based on current community info about standard awakenings in the game, and Vessel is described as having an Ultimate/awakening-style state rather than a separate timed mode in the sources I found.

Quick Scoop

  • Typical duration: around 60 seconds for standard awakenings.
  • Vessel-specific note: current guides/wiki pages confirm Vessel has an Ultimate: King of Curses , but they don’t clearly list a different timer for Vessel itself.
  • So the safest answer: expect roughly 1 minute unless the devs changed it in a recent update.

What that means in-game

If you’re asking because you want to know how long you can stay in Vessel form, plan around a one-minute window for combos, pressure, and repositioning.

That lines up with how most awakenings work in the game, while special cases like Hakari or Higuruma can last longer or shorter.

Community context

Players discussing ult durations say standard awakenings are usually one minute, which is why Vessel is generally treated the same way unless a patch note says otherwise.

A newer Jump Showdown guide also confirms Vessel is a boss-character unlock tied to Jujutsu Shenanigans, but it does not give a different duration for the mode.

Bottom line

Vessel Ultimate lasts about 1 minute.

TL;DR: about 60 seconds , with no clearly documented Vessel-only exception in the sources I found.
