Art - Target question.

I already know the commands or strings for the Art- target or caster thing but what i want to know is, I cant seem to make a unit have his head on fire, I mean I can do it if I add a item to his invenitory, but I dont know how to have his head on fire the whole time with out any items I just want to know when you editing the character where you put the Target Attachment Points for the units editor.

special effect - attach a special effect to the head of (unit) using (special effect)

just make a trigger that does this when the spell is cast.

Thanks you I got it now.
