|I made custom events for my mage for Fingers of Frost and Fireball! - both use the same settings as the Clearcast buff (but colors changed) and restricted to the Mage class.
Fingers of Frost works fine, but Fireball! will not work. I've tried the search as both "Fireball" and "Fireball!" but it won't come up. It came up before the update for the 3.3 patch, but hasn't worked since.
