SunwellAlarm is built in the spirit of SolarianAlarm. It does 3 things.
1) Turns the screen blue for a few seconds if you are burned on Brutallus so you know to move.
2) Turns the screen blue for a few seconds if you are targeted with a beam on Felmyst so you immediately realize it's you that is targeted.
3) Turns the screen blue if you are targeted for a Conflagrate on the Twins.
The addon is written so it should work for any language of WoW however the text output in the chat box is only available in English at this time but would be trivial to translate.
Commands:
/swa test - Puts the addon in test mode for 10 seconds showing the blue screen so you know what to expect.
/swa version check - Shows you what versions of Sunwell Alarm your raid members are using.
