I am currently 77 slayer going for 85. I am using bone bolts due to how cheap they are. I was told I should use a c bow if I am ranging slayer. To get this I would need to do regicide, underground pass and roving elvs. Would it be worth my time/money to do all these quests for slaying? Or should I just stick with my cheap bow and zammy book? I don't want to pay for mith bolts and up.
