Also this is not the main difference between Conjuration and Transmutation. The main difference is that Conjuration summons an object or thing, like summoning rubber, water or lighting. Transmutation copies the qualities and properties of a thing, like bungie gum copies to qualities of rubber and gum and Killua's aura copies the qualities of electricity.

You could conjure water or transmute your aura into having the qualities of water. The transmutation would be invisible because it's aura but if you transmuted oil into water the water wouldn't be invisible. The conjure water would be regular water.
