This article is about the slayer monster. For the superior variant, see Cave abomination
Cave horrors are a slayer monster 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 (e.g. 9 damage at 96). This attack can be completely nullified by either wearing a witchwood icon OR 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.
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.
Cave horrors are found inside Mos Le'Harmless Cave, located in the middle of the island next to the bay leading to the Trouble Brewing minigame. To get there, players may do any of the following:
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.
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.
