Cave crawler

Cave crawlers are Slayer monsters that require level 10 slayer to kill. They drop a variety of Herblore related items and a few seeds. They are, however, poisonous, and have an extremely fast healing rate (approximately 10 life points per second) making them somewhat more dangerous than their combat level suggests. When fighting the level 23's, a player shouldn't need much food; about 4-6 cakes worth (480 health-720 health healed) should do for a player with a decent defence level if an antipoison is consumed immediately upon being poisoned. They are also a great way to train Herblore, dropping several Herblore ingredients, herbs and vials of water. Cave crawlers also drop all the ingredients needed to make an antipoison (Unicorn horn dust, grimy marrentill which must be cleaned, and a vial of water) in case you didn't bring any. A Bunyip familiar would be perfect here, healing more than enough to compensate for the cave crawler's attacks. There is also a summoning obelisk in the Fremennik Slayer Dungeon in the same cave as the cave crawlers.

Cave crawlers are also a popular delicacy amongst the Dorgeshuun cave goblins, who cut them into fillets and serve them on a large platter. The poisonous parts of their body are presumably removed. Consequently, they are weak to all bone weapons, including Zanik's crossbow, which makes short work of most assignments.

In the quest Fur 'n' Seek, its hide must be collected and cleaned for the Odd Old Man (the gay one)

Locations

 * Fremennik Slayer Dungeon (level 23) - Recommended for slayer tasks and slaying in general. Many in one open space. (Fairy ring A-J-R)
 * Lumbridge Swamp Caves (level 23) - Recommended for slayer tasks for the nearness of a bank and for the fact that they drop whiteberries and rare herbs quite frequently. You need a light source, and a tinderbox is recommended. Note: A rope is required for first-time entry, unless you've started The Lost Tribe quest, in which case these caves can be accessed from the Lumbridge cellar. (The entry must be opened with a pickaxe the first time, but is just to the south after you enter the cave goblin tunnels.)
 * Dorgesh-Kaan South Dungeon (level 23)
 * Pollnivneach Slayer Dungeon (level 138)

Strengths and weaknesses
Cave crawlers poison fairly often so it is advised that players bring at least one anti-poison potion when fighting them. Their poison is fairly powerful and will initially cause 80 damage. Drinking a super antipoison prior to engaging in combat with them will prevent being poisoned for a good amount of time.

The level 138 cave crawlers are in a multi-combat zone, and it is recommended that you use a dwarf multicannon and protect from melee to slay. However, a slayer task may use up to around 1500 cannonballs to complete using this method. Level 138 Cave Crawlers are also considered large creatures so the Dragon halberd special will hit them twice making fighting them with melee in the Desert Slayer Dungeon easier with rocks to stand behind after they stop auto attacking you.

Level 23 and 138 cave crawlers drop all of the required components for many potions such as Prayer potion (Vial of water, ranarr and snape grass) at a fairly regular rate, allowing players to stay in the area for longer. They also drop all the ingredients for both antipoison and super antipoison which is very handy considering they poison so frequently. Some other useful potions made from their drops are Restore potion, Strength potion, Super strength potion, Super attack potion, Prayer potion and Super defence potion.

Due to an update, you can no longer use the Dharok method, as it doesn't work as they now have some sort of ranged attack, they will spit their poison at you and you are not immune to poison effects of this using a normal antipoison. Be advised that this was likely added to stop people from easily obtaining ancient effigies.
