Addon sends a message to general chat when you target rare Kor'kron mob in the Northern Barrens with it's name, health percentage and coordinates. Sends a message when rare is killed. Built in spam protection. Also will display how much time passed since you last witnessed kill of a particular rare in a small, movable frame, to help determine patterns and where next one will probably spawn.
