I got my runes after botting Escherion 72 hours straight. My friend got in 10 tries on Tibicenas. I suggest doing Escherion though. Although the drop rate is 0.3% on Tibicenas and 0.1% on Escherion, you can get many more kills on Escherion in a shorter amount of time without dying. I have several bots I would like to post, finding runes being one of them, whenever I get the permissions to post the antivirus scan links. I'm still figuring that out, but in the meantime if you know how just make a bot for Escherion farming. I suggest putting on a solo class before doing so to ensure that you don't die and also go in a public room so you have others to help you. Best of luck to you!
