Cave horror icon

Cave horrors are assigned by Chaeldar, Nieve and Duradel after completing the quest Cabin Fever. Killing cave horrors requires 58 Slayer, a witchwood icon, and a light source to see in the caves.

Cave horrors are often killed for their black mask drops along with a decent rate of hard clue drops.

A witchwood icon must be worn at all times while in close combat with cave horrors. If not worn, they will deal damage equal to 10% of your total Hitpoints level rounded down (e.g. 7 damage at 76 HP or 9 at 98). This does not affect other stats.


Cave horrors are found inside Mos Le'Harmless Caves. To get there, players may do any of the following:

Strengths and weaknessesEdit

Cave horrors use a Magic-based Melee attack, so it is advised that players bring Dragonhide armour or other armour that provides Magic Defence bonus. Players must also be wearing a witchwood icon, which can be purchased from any Slayer master. The cave horror will use a scream attack which WILL NOT reduce a player's stats however will deal damage to a player based upon their Hitpoints. Damage calculation (Player's HP level/10) rounded down to the lowest integer. However, the witchwood icon is NOT necessary when fighting them from a distance or when using the Protect from Melee prayer, so a better amulet may be used instead. Since cave horrors are wider than one square, a dragon halberd or a crystal halberd can be very useful as a special attack weapon, and can sometimes be used in the right areas to safespot the cave horrors behind the mushrooms, stalagmites, and boulders. 

Note: It is advisable to keep the witchwood icon in case of a close combat encounter. 


Estimated drop rates are based off 9,397 kills.[1]
