Hello all, i am interested in creating some custom content in a away like the lich king area, after certain quests,the npc spawns in the area changes as you progress through quests.I am wondering how this sort of thing is done, would like to do this sort of thing at storm wind.I just cant find information on changing spawns (like instancing) as you progress through quests.would be great if someone could give me info on how this would be possible as in, can it be done in the database, if so is it classed as a instance? or do you have to script it.Many thanks.
