Any ideas how I can detect exactly when this debuff is applied? I know I could iterate through my debuffs, but i'm wanting to find an event based way to detect when it is applied rather than checking constantly for it and comparing vs the remaining duration.
As you see, Chilled doesn't appear in combat log. You can work with PERIODIC DAMAGE but you don't know if the mage actually has the talent then
Anyway, you really should just check debuffs if that's an option
