Cave horrors are Slayer monsters found in the Mos Le'Harmless Cave. 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.

The cave horrors have a special attack which always deals damage equal to 10% of the player's base Hitpoints level, rounded down (for example 9 damage at 96 Hitpoints). This attack can be partially avoided by wearing a witchwood icon, OR completely nullified by having Protect from Melee activated. Using protection prayers allows players to use more powerful necklaces instead of the witchwood icon as it only provides minor bonuses. This special attack also has a strange effect of being an Area-of-Effect (AoE) attack in a single-way combat area, hitting any players standing next to the Cave horror not already in combat with it. Another strategy is to use safespots, but players should take caution leaving their safespot to loot, as the aggressive cave horrors may attack you. For this reason, if you do not have access to Protect from Melee, it is still recommended to bring the witchwood icon, or grab the loot using Telekinetic Grab.

Killing a cave horror is a task in the Hard Morytania Diary.

To get there, players may do any of the following:

• Use the free minigame teleport to Trouble Brewing in the Grouping tab, found in the chat-channel tab.
• Drink some 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 Arceuus spellbook, completion of Great Brain Robbery) and talk to Brother Tranquility.

Strategy

While cave horrors will always use their special attack when a witchwood icon is not being worn, wearing one will make them alternate randomly between kicking every 4 ticks, and screaming every 5. When fighting cave horrors, players will need to either use Protect from Melee to negate all damage, or wear a witchwood icon and armour that provides high Magic Defence bonus (such as dragonhide armour) against their special and Magic-based Melee attacks. Wearing a witchwood icon is necessary if not using Protect from Melee, as otherwise players will take heavy damage from the special attacks over time.

Cave horrors have fairly low Hitpoints, and they are relatively spread apart, so it is generally best to use a fast-firing Ranged weapon like a toxic blowpipe, magic shortbow (i) or Karil's crossbow. If using Melee, it is recommended to use equipment that provides high Prayer bonus (such as Proselyte armour) and always use Protect from Melee so a better amulet can be used. A dwarf multicannon can also be used to speed up kills. Cave horrors can alternatively be safespotted by using the mushrooms, stalagmites, and boulders inside the cave, such as the area by the swamp near the cave entrance.

When cannoning, consider using a bonecrusher necklace, which will comfortably maintain Protect from Melee without using any supplies, as the Cave Horrors drop Big Bones.

Consider bringing a log basket or a plank sack with Plank Make, to store the unnoted Mahogany logs they frequently drop in a single inventory slot.

Switching to the Arceuus Spellbook and bringing runes for casting Adept Reanimation should also be considered for passive prayer training as ensouled horror heads are frequently dropped.

Note: It is advisable to keep the witchwood icon in case of a close combat encounter if safespotting, or in case you run out of Prayer points.
