Illusions?

Is the only way to make an illusion of a unit to use the item ability "Item Illusion" 'AIil'?

(In that case; what do I do with the casting unit? make it a hero and give it the illusion-item? :P (the ability lacks orderstring))

Just use an orderid

orderid!?
orderid=orderstring?

Sorry, but I'm not used to doing this stuff.

Not at all?

Download my caster system's map it has got illusions' orderid

I have the caster system? Yay! Questionified statements!
(though it was a long time since I checked the demo-spells).

...

Anyway, thanks a lot :)
