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 (unless a Fire of Eternal Light is lit) 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 the player's total Hitpoints level rounded down (e.g. 7 damage at 76 HP or 9 at 98). However, a witchwood icon is not required if the player always has Protect from Melee active or is using safe spots.
Cave horrors are found inside Mos Le'Harmless Caves. To get there, players may do any of the following:
- Use the free minigame teleport to Trouble Brewing in the minigame tab.
- Drink a Mos Le Harmless 'rum' bought from Honest Jimmy for 20 Pieces of eight.
- Use the Ectophial to travel to Port Phasmatys and then talk to Bill Teach to sail there.
- Use the Charter Ship to sail there.
- Teleport there using a Mos le'harmless teleport scroll, and then walk to the cave.
- Harmony Island Teleport (Requires ability to use of Arceuus Spellbook, completion of Great Brain Robbery) and talk to Brother Tranquility.
Strengths and weaknesses
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.
