This guy spawns every 6m40s and should stay blue till 60 and is very easy to kill, can most likely do without epic and fungi. Not going to be amazing exp but it moves the bar and is safe. At level 57 I got 1% exp after 4 kills. So maybe 2% an hour in the mid 50s. Also drops a longsword and 1 to 3 plat per kill. Good afk camp.
