unit settings

how do you make a unit have 0 cool down for an attack? the editor allows me to do it but it doesnt actually change it. how do i change it so it would work. or can someone give me an editor that can change this

Been asked before...
Base it on a unit that does not initially have an attack. Change the models and edit all settings.

but if i base it off of something like a wisp, it has no attack settings except for projectile speed and projectile art

Then don't base it on a say, wisp?
