Help Impersonate Spell

I'm having trouble making this spell. I want it to make a copy of an enemy Hero and give that copy the kaboom ability. Trouble is, illusions can't have abilities. Can someone help me with this plz? Post the trigger or something?

that is a challenging one. you would have to fake it with a trigger. for example:

event:
illusion comes within 250 of enemy hero

action:
explode triggering unit
create kaboom special effect centered on triggering unit
deal x damage to all units within y of triggering unit

its rough, but i cant think of a better way to do it. you may have it fire only for structures and heros, to keep it from being wasted. up to you and your map needs.

edit: itd be kind of wacky if you had the illusion chase the "real hero" and explode when it caught up to him. :)
