Cave crawlers are Slayer monsters that require level 10 Slayer to kill. They can inflict poison, so it is advised that players bring antipoison potions when fighting them. They are the only enemy to drop bronze boots. They also drop a variety of Herblore ingredients, which can be helpful for lower level players looking for an alternative source of herbs over more popular sources, such as Chaos druids.



Players with very low Defence should use Ranged or Magic to attack these monsters in order to avoid being damaged and possibly poisoned, utilizing the rocks around the room's walls in Fremennik Slayer Dungeon as safe spots. When fighting cave crawlers in the Lumbridge Swamp Caves, be aware that any exposed light sources (i.e candles) may explode, and can cause a considerable amount of damage. As such, a bullseye lantern is recommended as it is not an exposed light source. You can use the fairy ring just outside as a fast means of banking.

As mentioned above, players are advised to bring antipoison potions as cave crawlers have a chance to poison you when they hit. They also drop the ingredients to make them yourself. Note that it is recommended to use antidote++ as it is cheapest antipoison available, and it lasts for 12 minutes for each dose.

Much like banshees, cave crawlers regenerate their health back quickly, gaining back 1 hitpoint after every attack.
