Hunter is the next skill, and Birdhouse runs are effectively the fastest hunter xp per hour but only until level 80 hunter.
Even if you do efficient redwood birdhouse runs, your hourly xp rate only averages 220k.
At 80 hunter you unlock the ability to place 5 traps at a time in the wilderness. If youre catching black chinchompas with 3-tick trap placement, you can get up to 220k xp per hour at 80, and 240k at 99.
If you bring along an alt to kill stray chinchompas you can get 235k at 80 and at maximum, you get 280k per hour at 99.
