Mob spawn in diff zone
 

I can't seem to remember if there was a way to get an npc in one zone, rather than spawning a mob in that zone in a diff location, but be able to spawn the mob ( or mobs ) in different areas when the timer is done on the primary mob that is in a different zone from all them.

Only way I can think of is to set a short duration mask 7 qglobal when the timer is done, and in every zone you want the mob(s) to spawn in, have a watcher looking for the existence of said qglobal.
Using that and a little creativity and you should be able to handle any desired outcome.
