Illusion dust

Illusioners should be able to drop "illusion dust" which can be used to brew a potion which will make you invisible and get a bunch of fake clones of yourself around you just like the Illusioner does for 15 seconds. on the other hand if you make the potion into a splash potion it will give you blindness for about 15 seconds. also I think the potion should be called "potion of illusions"

The potion will have 2 types, 1. is the normal one that you craft with the illusion dust which makes you invisible while also putting in fake clones around yourself for 15 seconds, and when turned into a splash potion will give the target blindness for 15 seconds. And 2. when you add redstone to the potion when drinking it you will have the clones appear around you, but you wont become invisible and the potion will last for 30 seconds. And the splash potion will give blindness effect to the target for 30 seconds.
