It's a good investment to kill , particularly with falador shield 4. Instead, go with a terrorbird and ensure that it engages in fight with the RS gold mole each day. The result is that the terrorbird begins to follow the orientation of the mole even when it is dug giving you a clear idea where it may be.
Additionally , the terrorbird lets players to run indefinitely (with it's scrolls) that is a huge helm. If you're looking to range, use a general ran setup of Dragonhide , with a few Prayer or Defence bonuses mixed into (Helm of Nietiznot for example). I think ruby or diamond bolts (e) are the most appropriate to use. If you're meleeing whip/chaotic rapier and DDP/claws. If you're a melee, you should bring proselyte armour to preserve prayers and use for piety.
To melee, would guthans , a super set and barrows gloves prove effective? I was playing with the range set up (rune plate granite shied the hide) and it didnt hit more often, so I thought guthans, barrows gloves and some super sets cheap OSRS gold could be really useful and id earn more money since i would not need diamonds or food as much?
