I have no idea what cursed technique I'm gonna give MC for my Gojo x Fem!Reader book.
I have cursed speech from the Inumaki Clan
I have cursed vision. The user is able to channel cursed energy into their eyes and see every angel of their enemy. Can only focus on one enemy. Can't see as fast as light (obviously), and their technique is triggered by raw sight (meaning there's no protection over their eyes to prevent the technique from triggering), it can be stopped by bandanas, bandages, but not sunglasses and glasses.
I have cursed manipulation into electronics (almost like Kokichi Meta with Mechamaru). User can manipulate cursed energy to operate machinery within a 1 mile radius. But, the user MUST know where the electronic is. If they don't, then it can't be affected. If it's on battery power and user knows where it is, they can use it for as long as the battery lasts. If it's battery powered but is dead, and user knows it's there, then it can't be manipulated.
This is all I have so far. I'm still deciding.
