So Jacob’s ladder nullifies cursed techniques and jujutsu, making it lethal to sukuna who is a cursed object. But what exactly does it do against normal sorcerers, other than deactivate techniques? Does it actually hurt them? I remember sukuna saying yuji got burned in the light but yuji also contains cursed objects and is a death painting, so what does it do to normal sorcerers?
