How do you use an item, wait for story and then attack and kill the mob when they do not attack you? It's for this quest http://www.wowhead.com/quest=26674/mistmantles-revenge 

and I have 2 objectives 1 to use the item at a hotspot, 2 to kill the mob that spawns after the story. Uses item fine but keeps using item on cooldown and will never attack mob?

Thanks

bump

I even put this in before pulse runcode for attack before attacked and it still won't move to the killloot part

http://www.wowhead.com/npc=315/stalvan-mistmantle he is an npc if that matters?
