Harpie Bug Swarm

Harpie Bug Swarms are Slayer monsters that require level 33 Slayer to kill. A Lit bug lantern is required to do damage on them.

Players often kill them because they have a good chance to drop level 2 clue scrolls, and have relatively low defence, they are also a good source for fire runes. They are aggressive to players under level 93.

Strengths and weaknesses
Harpie Bug Swarms use rapid melee attacks and do quite a bit of damage for their combat level. If a lit bug lantern is not equipped any attacks on them will be ineffective. A fast-hitting weapon helps to get rid of them quickly before they do too much damage.

Alternatively, players can mage or range Harpie Bug Swarms from the Eastern side of the stream at the eastern end of their habitat, to avoid taking any damage from them, although this does mean expenditure in terms of runes or ammo for ranged weapons. Note: Ava's device, a reward from Animal Magnetism quest, does not work across the stream to retrieve bolts.

Although not in a multi-combat area, a Cannon can be used to take down the swarms in one hit fairly often.

Another viable strategy, for those that have finished the Tai Bwo Wannai Trio quest, is to use Protect from Melee prayer, and refilling prayer points at the Tribal Statue in the village, a short run away. In this case, prayer boosting armour is recommended to increase fighting time.

Location

 * Karamja

Other
Since they are close to the Karamja general store, it is possible to restock on food there as well as sell drops. This way banking off the island is unnecessary. However, if one wishes to bank, there is a bank in the TzHaar City, found beneath Karamja Volcano, and the route is made shorter with the mithril grapple shortcut, or you may also bank in Shilo Village after the quest, Shilo Village. Also, Rionasta in Tai Bwo Wannai Village can send items to the bank for 10 trading sticks per item, although he cannot take items out of the bank.
