This is quite good, but you'll run out of inventory or time slots for the terrorbird before you get to this it seems like, Maybe just the monks in RuneScape Gold your inventory. However, it seems that the b2p can be used at around 80 defense. But the terrorbird isn't going to hurt, I'd guess, just play with it.
It's extremely profitable killing a falador, especially if you have shield 4. If not, you can use a terrorbird and ensure that it engages in combat with the mole every one time. The result is that the terrorbird begins to follow in the general orientation of the mole even if it has dug, giving you a clear idea the location it might be.
Additionally , the terrorbird permits you to run forever (with its scrolls) that is a huge helm. If you're looking to range, use the general run set-up of Dragonhide and some Prayer or Defence bonuses mixed in (Helm or Nietiznot for instance). I believe that diamond or ruby bolts (e) are the best ones to utilize. If you're using whips, chaotic rapiers and ddp/claws. If you melee bring proselyte armour in order to protect the prayer pots and make use of to practice piety.
To melee, could guthans and osrs equipment buying sites a super set be effective? I was just at it with a range set up, (rune plate, granite shied, otherwise the hide) and it didn't hit more often, so I thought that barrows' gloves, guthans and some super sets could be extremely useful and gain money faster since i did not use diamonds and food as much?
