Through the power of the Eternal Mangekyō Sharingan, you gain the ability to turn anything seen with the eye into a genjutsu, or turn a genjutsu real. With skill in manipulating genjutsu, this can be used to achieve limited reality manipulation, although overuse can cause rapid eye pain. If you see an ally about to be hit by a bullet, for example, you can make it so the bullet does no damage by turning it into an illusion. The only thing not affected by this is wounds already inflicted, so you cannot cause or heal wounds via this, but you could use this to avoid Amaterasu flames by swapping yourself being burnt into something else, so long as the flames don't reach where you can't see.

Your previous limitations have been lifted, your powers itself has been greatly enhanced. Now you possess the ability to create a field up to a radius of 100 meters from your body. This range can be increased over time, not that you’d necessarily need to as within this range you're effectively omnipotent. While anything would need to be in your field to allow this ability to affect them, living things only need to be partially inside your field in order for you to affect them. i.e. if you were to have someone send an avatar, you'd hit their real body as soon as the avatar stepped foot in your range. You can create a single field or multiple fields, and are able to shape the fields however you like provided they are within the stated range.
