JJK [Prison Realm/Gokumonkyõ]

The mod adds three items

 one of them being Sukuna's finger

 which if you eat you will gain several good effects such as attributes of strength, speed and other things and if you press the button (M) you will activate vessel mode from the king of curses which will give you good attributes again

the second item is known as prison realm 

If placed on the ground when interacting with it, it will open and any player within range will be sent to another dimension (if an arrow hits the prison realm it will also open)

After that it will close and turn blue and if you interact with it again it will return to its original form and all players trapped in the dimension will be teleported to the overworld again.

The third item is an artifact that if interacted with will give you good status

(if you see any kind of glitch or any error or anything like that, please leave it in the comments so I can fix it)
