Kill hobgoblins in a Bounty Hunter world. They're located in level ~35 wilderness, northwest of the volcano. Only grab the limpwurt roots they drop. Make sure you have about 10-12 lobsters, or enough to get to a safe spot. Use the banker south of the volcano. They're aggressive to everyone, so you don't have to worry too much about another PKer. When you get a target, kill them (easier said then done, I know). No arm them if you have to, make sure you don't die (anchovy pizzas and swordfish). If they die in full rune, your drop will be ~200-300k. If you kill your target, or die, and your EP is greater than 50%, skip killing hobgoblins and kill people until your EP is under 50%. The idea is that you never let your EP reach 10% or 100%. If you're good enough to kill your targets, and don't die, you should get on the order of 400k-500k / hour. I usually don't havr any problems on targs but some of those kids are nuubish and safe a like a fire right under them.
