new idea: remake nk system
killing player in certain map will gain nk,when you reach x amount ,you cant leave current map, log off,back to town,or teleport(npc/wizard spell gate).
this nk cant be remove from anthem,
when killed by same nation player ,value only reduce half.
killing same player will still gain nk....killed by same player more than 2 time.wont reduce your nk
this nk wont affect movpment speed,or droping items
