The Giant Mole is located in the Mole Lair under Falador. The entrance point is located at Falador Park, where there are mole holes scattered on the west side. The closest teleport is the Falador Park option(3) on the Ring of Wealth. Players must bring a spade to dig underground and a light source of some type is required or they will be constantly bitten by bugs. A Fire of Eternal Light can be lit inside the cave after completing the Making Friends with My Arm quest which provides permanent light inside the cave.
Attacks and abilities
Melee attack: The mole swipes a claw at its target, dealing up to 21 damage.
Burrow: When the mole's health is between 5-50%, there is a 25% chance for any incoming attack to cause it to burrow away into another location. There is also a chance that the dirt she digs while burrowing to escape can extinguish the player's light source (shown with dirt splatters on the player's screen), though covered light sources will be unaffected by this. Note that splashed magic attacks cannot trigger her to dig, making weapons such as the Tumeken's Shadow particularly good for fighting the mole.

Killing the mole is easy, as it doesn't have any unique abilities that can endanger the player.
For low levelled players, they can safespot it with the cavern walls, as it does not move around the safespot to attack players. Ranging is highly recommended when safespotting, as it has low ranged defence. Players meleeing it should activate Protect from Melee and use stabbing weapons, as it has lower stab defence compared to slash and crush.
When the mole reaches half health and lower, there is a chance that it will dig away to another location in the lair. Without the Falador shield 3 or 4, it can be a tedious task, as players may have to navigate through the whole lair to find the mole. The mole also loses aggression towards the primary target when burrowing away. Thralls can be used as a makeshift substitute for the Falador shield, as they will begin to path towards the mole's new location after she digs in order to attack her.
Completion of the hard Falador diaries is highly recommended, as players with the shield can locate the mole whenever it digs away. It also notes the 100% drop of mole skin and claws, prolonging trips.
Equipment
Currently, the Twisted bow is one of the most effective ways of killing the Giant Mole. It offers some of the highest damage of any setup. A dwarf multicannon can also be brought to speed up kills.
Currently, the Tumeken's shadow is one of the most effective ways of killing the Giant Mole. It offers some of the highest damage of any setup, comparable to using a Twisted bow. Due to Mole's 50% weakness to water, water spells are effective for accounts without a Twisted bow or shadow who wish to safespot. A dwarf multicannon can also be brought to speed up kills. An added bonus of using Magic is that splashes cannot trigger the mole to dig, meaning players won't have to chase after the mole as much compared to other combat styles.
Dwarf multicannon and cannonballs to speed up kills (not actually faster because of shadows accuracy mechanics doesnt hit and rolls for dig even if canon hit is 0)
Using Dharok the Wretched's equipment offers fewer kills per hour than the Armadyl crossbow, but is a much more affordable option for most players. Use the locator orb or a dwarven rock cake to get down to 1 Hitpoint. Always keep Protect from Melee on when you're attacking the boss.
If the player does not own a cape that provides a Strength bonus, they can instead use a cape that provides a prayer bonus to maximise the amount of time Protect from Melee is active before needing to restore Prayer Points.
Using melee without Void Knight equipment offers less kills per hour than Void or Dharok the Wretched's equipment. This setup has the advantage of using cheap gear and not requiring untradeable items, making it more accessible for newer players. You should Protect from Melee when in combat with the Giant Mole.
