So you want clones or illusions?
Like, okay, both can go hand in hand, but you'll have to reduce the various effects of illusions and clearly define them. They don't make too much sense as they are now. Keep the amount low and the detail high.
Also why are illusions all around better than the original? Sounds kind of ehhhh. How many can he make of people? Or animals? Some animals are much better as pawns than people in fights you know.
Limit/weaknesses seem okay I suppose.
Also Illusions are good for both defense and offense. Js.
