Custom Abilities, empty button?

I forgot how to do this, but I need to be remembered how I can get a generic ability button on a hero with level associated with it, so I can just click the button and make a trigger do the entire effect. Stupid brain!

Use the moon glaive ability.

Isn't that a passive ability? I thought there was a generic ability.

Use the Channel ability (neutral hostile) it is extremely versatile and has no actual affect.

EDIT: Just ignore me, I'm being stupid.

But that doesnt change the fact moonglaive is passive. You have been reading his posts havent you th15.
