Sphere (Vengeance) Not Working on Evil Illidan?

I can't get the sphere ability to work on a unit other than the Avatar of Veangance. >.>

change the attachment point refference and don't post these things in the trigger haven

only bloodmage and avatar of venegance have sprite attachment points, demon hunter can't hate sphere effects over his head

The ability sphere can be given and function on any unit, however, you must change the attachment points to something that the unit has. As stated earlier, the only units with the sprite animation points are the Blood Mage (3 I believe) and the Avatar of Vengeance (around 7 or so). Just change the animation point to something like head or chest and it'll work fine.

As a point of technicality, I believe many building models have sprite attachment points which are used by the "On fire" effects when the buildings are damaged.

Not that it's likely to be important to the matter at hand.

The flying machine and the crypt lord also have sprite attachment points
