Just replace the
Text to match part with the spell name or something. Or if you wish to get more specific, you can write something like "Soandso's Spell Name hits". Notice the
Trigger timer checkbox, and textbox next to it... that's where you enter the name of the spell timer that you create. Remember... name it something that would not get triggered otherwise.
