It's fairly lucrative to kill especially with falador shield 4. In other words, make use of a terrorbird and make sure it initiates combat with the mole every day. The RuneScape Gold result is that the terrorbird begins to follow in the general orientation of the mole, even when it has dug, giving you an idea of which direction it is located.
Additionally the terrorbird will allow the player to run endlessly (with it's scrolls) which is a huge helm. If you're ranging use the general ran set up of Dragonhide with some Prayer or Defence bonuses mixed into (Helm from Nietiznot for example). I believe diamond or ruby bolts (e) are the best ones to utilize. If you're using whips, chaotic rapiers and the claws/ddp. If you're meleeing, bring proselyte armour , to preserve the prayer pots and make use of for piety.
To melee, would guthans , a super set and barrows gloves make a difference? I was playing with the range set up (rune plate granite shied you hide) and it wasn't hitting every time, so i thought that barrows' gloves, guthans and some super sets how to get gold in old school runescape could be extremely useful and earn more money since i would not have to use diamonds or food as often?
