So to begin start off by talking to the Skilling Supplies Npc,and buy a few bird snares,and 4 box traps,then go to "skilling teleports" NPC,and go to 2nd page,and go to hunter.
From here you will walk along the coast and find crimson birds,u gotta set up\dismantle to get a bird,but only need to catch 1 bird to for 27 hunter.
At 27 hunter, walk to the "hunter" paw icon on map,where red chins are located,and start setting up box traps and wait for chins to trigger the trap,and keep doing this. I am currently 77 hunter and will post more if I i find faster methods to get 99!
