Help linking orb abilities to triggers.

I was just wondering if anybody knew how to link an ability, that is activated through an orb ability, to a trigger. I used my event as "ability being cast", and my condition as the orb ability, but that didn't work. Then I changed my condition to the ability the orb ability casts, but that didn't work either. Any help would be apprecitated.
Thanks.

doesn't work.

Best solution: Trigger the orb (not as easy as it should)
