Hi, I was wondering what a good combat level for completing the Shilo Village quest is? Currently it is level 50 (36 att, 36 str, 36 def, 50 range, 37 magic, 44 prayer), and I want to know when I should start the quest. It says I need to defeat a level 86 monster, but I know there are two others before that. Is magic effective against this boss because I would rather defeat him using that. Thanks :D
