Cave horror

A Cave Horror is a Slayer monster that requires level 58 Slayer, a Witchwood icon, and a Light source to successfully hunt and kill. You must also have completed the Cabin Fever quest to have access to Mos Le'Harmless, as cave horrors live in an unlit cave on this island. They also have a weaker relative outside on the island called Jungle Horrors.

Players can buy a witchwood icon from any Slayer Master and must wear it while fighting cave horrors in close combat. You can damage them without the icon, but the icon protects against the cave horrors' screams. Without the icon, the scream reduces your stats by a significant amount, similar to the effect of a Banshee when fought without Earmuffs. The scream can also inflict damage which is not blocked by the icon.

The witchwood icon is not necessary when engaging in long range combat from a Safe spot, so neck wear with better combat modifiers can be worn instead. It is recommended to carry an icon in inventory when using this tactic, in case close combat occurs by accident.

In contrast to most RuneScape monsters, the cave horror does have quite the irregular attack speed, which can shift in the middle of a battle. Time between attacks can be either 2.4 seconds or 3.0 seconds. This makes it somewhat difficult to utilise tactics such as prayer flashing effectively. However, this is compensated by their generally low amount of hitpoints.

Cave horrors are generally known for dropping black masks, and even though black masks are effectively the best drop from them, they aren't very rare.

Cave horrors are an effective place to train ranged for players with 85+ ranged looking for a chance of high profit (from black masks and various seeds) as well as a decent amount of crimson charms.

Locations

 * Mos Le'Harmless Caves - in a cave on the south(-east) side of the island. You need a light source (such as a Bullseye lantern) to operate in the cave. Without a light source, it is nearly impossible to find your way in the cave.

Tactics
An effective method of killing cave horrors is as follows:

Meleers should use armour that is high in magical defence bonus (+100) whilst at the same time not giving negative offensive melee bonuses such as: Karil's leathertop, Karil's leatherskirt ,helm of neitiznot, or for those who wish not to use degrading armour black dragonhide armour can be used, however it is not advised if one's defence level is below 90 and magic level is below 80. Some people may find that using the barrows set Guthan's effective however if one uses this method it is advised that they bring prayer potions or super restore potions in order to restore their prayer points. People often over-exaggerate the "danger" of cave horrors. Black D-Hide, Whip, Obsidian Shield, and a bunyip will keep you there long enough to fill your inventory, although you should take 8 monkfish or so just-in-case (80 def. and 70 mage).

It is recommended a beast of burden familiar be brought for the extra food spaces or a bunyip to counter the hits of the Cave horrors. Food that heals 140 or higher is highly recommended.

Rangers should use the below shown safe spot, or very few other safe spots if they wish not to receive damage from the cave horrors and reasonable ranged attack bonus (+160 is preferable). If one wishes to use the method of tanking (taking the hits of the cave horrors) whilst ranging it is advised they have high magical defence (+100 magical defence bonus, 85 defence, 75 magic). Knives, darts and shortbows are very effective against these when a player has high levels in ranged (80+)

If you have a guthan's set, albino bats can be found throughout the cave which are ideal for healing.

Sacrificing magical defensive armour for equipment like Dragon Boots and the Toktz-ket-xil which give significant strength bonuses, and a fast weapon such as an Abyssal whip or Saradomin sword, can be used for quick kills. This is effective because the monsters only have 550 life points, and can be easily taken down by a player with 70+ strength in about 3-4 hits.

A Halberd may also be used for killing Cave Horrors in one of the safespot locations.

Warning: If you forget to bring a witchwood icon and fight cave horrors with melee without stopping, you will get hit for 80 each time it attacks.

Trivia

 * The faces of Cave Horrors are most likely based on the faces of "ReDeads" from The Legend of Zelda series, more specifically the Ocarina of Time/Majora's Mask incarnations.
 * The way they stand/walk is also similar to the Shadow Beasts from The Legend of Zelda: Twilight Princess, which also wear black masks.
 * Although the Hexcrest & Focus sight are related items to the Black Mask, they appear in the Adventurer's Log, while the blask mask does not. This is probably due to the higher levels required to obtain the Hexcrest & Focus sight, but may also be because the black mask has been in-game for much longer (and therefore may have been looked over.)
