Combat Log Matcher
Matcher against strings in Combat Log ex: Something nearby casts Whirlwind and you get an aura.
Spell Alert will do this now
Usefull here too would be to set an aura for example Halion fight, chat says "The orbiting spheres pulse with dark energy!" and currently after u need to be moving from beams.
Chat and combatlog monitoring would be really nice and expand Power Auras greatly.
Alternatively, provide a convenient Lua function that other mods can call to trigger a particular aura being displayed. That way other mods like ThatJustHappened or Execution, which already have a fully developed and sophisticated set of customizable combat event monitors can just add a rule whose output is triggering a PowerAura, instead of PowerAura trying to replicate their functionality.
This is going to be very helpful for overall awareness of a fight in Battlegrounds which will be rated soon enough.
