A WA that gives a visual and audio cue to all mages in a raid group when the first scorch is being cast, as well as a 1.5s timer to start casting theirs. This is important because it ensures that the weak scorch ignite is dropped before the first mage's fireball goes off, so that a larger ignite can start.
Note - on multi-boss encounters (e.g. bug trio), only first scorch of encounter will trigger warning. I'm new to this, so if you have a way to do this, lmk!
