Called when a spell timer is created, restarted, or has a DoT tick applied. In other words, any time the window is notified about a spell it is actively keeping track of. If you need to know if the event is called off of a start/restart or a DoT tick, check the MasterTimer property of the last SpellTimer in TimerFrame.SpellTimers.
