Okay so as I'm on vacation as I have said. I'm going to tell you that you guys will get this, but here me out.

You get this when you have absorbed every chakra nature. But you have the eyes of UI as of now when you activate your Sharingan if it makes sense. IDK how else to say it.

no you won't have energy attacks like the kamehameha, but you will do jutsus alot faster that the sharingan, byakugan or Rinnegan could follow.
