Hello, I farmed elemental fires for 1 hour. This location is also solid XP for lvl 50s.
Server: Bigglesworth
Class: Rogue
Location: The Cauldron (Near MC)
Mob Name: Magma Elemental (lvl 47) @ Blazing Elemental (lvl 46)
Time: Late as possible
Results: 8 elemental fires @ 3 heart of fire + vendor items = 51g
I also created potions before and soled them while farming which made me an extra 20g that hour.
