Help how to remove a particle from a item set?

Tairow

Hi everyone, I'm creating a item set for Death Prophet, its been a long time since I've created something for dota and last time was just a sword, but this time I'm having trouble with the particles of the original set, in the base set the head have a particle system that's not needed for my set, how do I remove it? 



By the way what you think about my head piece??

Thanks everyone!
