I need help making a sound trigger when I use a spell!

[signal mesa]

I've been trying to make a sound trigger when I use the "Fire Breath" spell on my evoker. But I can't seem to get it to trigger no matter what I do. I'm prety stuck, any help would be much appreciated

You got a couple triggers available for that

Player/Unit Info -> Cast -> unit = player -> Fire Breath
Combat Log -> Spell Cast Success -> Source = player -> Fire Breath
Other Events -> Spell Cast Succeeded -> unit = player -> Fire Breath
