fire wont attach?

I'm trying to get some fire to attach to my abominations chest, but i cant get it to work. ive tried this trigger:
but it doesn't seem to work. I've also tried going into the object editor and making an ability but that doesnt work easy. I based the ability off of hardened skin.

overhead isn't going to attach it to his chest, it'll attach it over his head. if that problem is that it isn't appearing then try origin, almost all models have it.

Change "Triggering unit" to the appropriate unit, if it's a preplaced unit use "Select unit" instead.

EDIT!
Also, there are sometimes issues when dealing with "Map initialization", but I'm not sure if that includes Special Effects.

Well of course that trigger isn't going to work.

You're using Triggering Unit without a unit event, so it's referencing no unit. Also, overhead won't attach to the chest like you want.

Use an ability like Tornado Aura (Slow) and give it to the unit you want to have a SFX attached to. Just modify the ability. It has no buff or icon.

Wow, I feel like an idiot now lol. Going too fast. Thanks for the help, and i put it on overhead to see if the units model wasnt blocking it and forgot to change it back.
