Cave horrors are a slayer monster found in the Mos Le'Harmless Caves. Killing them requires the completion of Cabin Fever, level 58 Slayer, a witchwood icon, and a light source (unless a Fire of Eternal Light is lit). They are most often killed for their black mask drops along with a decent rate of hard clue scrolls.

A witchwood icon must be worn at all times while in a cave horror's attack range; if not worn, they will always deal damage equal to 10% of the player's base Hitpoints level, rounded down (e.g. 9 damage at 96). However, players don't have to wear the icon should they have Protect from Melee activated, or are using a safe spot. Despite this, it is still recommended to bring an icon and wear it once the player has killed a horror, as aggressive horrors may attack the player while they are looting their drop.

Location[edit | edit source]

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

Strengths and weaknesses[edit | edit source]

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.
