Ability/unit Question! HELP PLZ!!

I need to make a unit be attached to another unit. I want to upscale a 'misha' and then downscale a shade. That part is done. But I want to shade to be attached to the misha and follow it and swirl around it. How would I do this. I have tried it this way:

Give misha the sphere ability, and change the model of sphere to shade. but sphere has no model file.

Any help would be great, if there is another way of doing this please help me.

Its in the sphere ability. Go there and select the model you want to spin around it head. or wahtever.

Can you please be more specific. Sorry but I am a complete nOOb.

try to use the trigger "attach special effect to unit" and select the shade model as a special effect

I have done this before with other units and it worked

Good God MAN! Thank you soooo much.....I have been trying to figure that out for almost 4 hours! Thanks a bunch.!!!

Never liked that trigger. The "Sphere" ability is much better.

The trigger is good when you want to do it for normal units, like buildings, or footmen, or w/e, but it doesn't work well with abilitys... Mirror image for one.
...

The sphere effect is the target called one, the special effect trigger won't work too well, it tends to disappear after a while and to lag you to the hell

as far as i could see, the sphere ability works only on blood mage model :)
it seems that i am wrong....does any other model except the blood mage has the sprite attachment point ?
and why doesn't it work (the original sphere) when i give it to any other unit ?:)

Well I'm not sure why it wouldn't work for you Shark.
It's working in this abandoned map I attached so maybe you could have a look at it and figure out what's wrong with yours. Look at the captain, I gave him the sphere ability, and changed the model to a tornado so it has tornados swirling around him.

because you forgot to change the attachment points?

The "sprite 1","sprite 2" and "sprite 3" has only the blood mage and the avatar of vengeance but you can change attachments of sphere to other things...
