It's rather profitable to kill especially with falador shield 4. Otherwise, use a terrorbird and make sure it initiates fight with the mole every time. What will occur is that the terrorbird will begin to RuneScape gold follow in the overall direction of the mole even though it's dug, giving you a excellent idea where it could be found. Also the terrorbird will allow you to run infinitely (with the scrolls) which is a massive helm. If you're ranging use a general ran setup of Dragonhide and a few Prayer or Defence bonuses mixed up (Helm of Nietiznot such as ).
I think ruby or diamond bolts (e) are best to use. If you're meleeing whip/chaotic rapier and ddp/claws. If you melee bring proselyte armour to preserve prayer pots and use piety. To melee, would guthans along with a super set be effective? I was only at it with a range set up, (rune plate, granite shied, otherwise d hide) plus it didnt strike too often, I figured guthans, barrows gloves, and also some super sets woul be very useful and id make money quicker cause identification not use food and diamonds just as much?
If you secure place (using the small gap beside the obelisk, therefore it will not even strike you until after it burrows) you won't require much food, if any. Guthan's probably wouldn't be very efficient. I advise that you utilize a broad/emerald (e) installation, begin with the emerald (e) to poison, change to broads to finish it off. Each kill is worth approximately 20k approximately. I myself do 2 kills each run (using eagle eye and also prot melee at times) then home interface, recharge pray at altar, use fally portal, lender and go back in time for OSRS buy gold another spawn to happen.
