I am trying to take a level 10 NPC and thought of a different way to take it!

Im not trying to make it a guide just wondering if it will work.

You would need atleast 2 citys near eachother, more is better (within 5 miles) and a level 10 NPC that you want.
Use camptime so that all of the waves hit within 10 to 30 seconds of eachother. Hopefully that would drop the loyalty lots.

If anyone has tryed this Idea and worked please tell me then I will make a guide on this!
