Adding Art Projectil at item

Hi all.

Since about 4-5 hours i'm looking to fix my problem, and i can't find anything.

I must add a projectile art at unholyfrenzy(the item). But when i add it, and use the item. No projectile is launched, but the ability work.

It's very important for my last map !

Thanks

As I recall, unholy frenzy doesn't use a projectile, so setting one will not cause a projectile to launch. You can go around this by making a dummy skill that does nothing except launch the projectile and when this spell is cast create a dummy unit that has the unholy frenzy, cast it on the target, and immediately remove the unit.
