This OSRS Cave Horror Guide will cover everything you need to know to slay Cave Horrors in osrs.
Cave Horrors are unlocked at level 58 slayer and are known for being the only monster that drops the Black Mask which gives a massive 16.67% melee damage increase (or 15% mage/range increase when imbued).
The black mask is also required to make a slayer helmet, a must-have for anyone who is training their slayer.
Alongside black masks which are worth good money in the grand exchange, cave horrors also drop a large number of high-level seeds, herbs, and nature runes so it is definitely a task you should not skip.

🗺️ Cave Horror Location
Cave Horrors are located in the cave on Mos Le’Harmless, an island that is unlocked during the Cabin Fever quest.
This cave is the ONLY place where you can fight cave horrors in Gielinor.
To enter the cave, you will need to have a light source.
You can easily get to Mos Le’harmless by using the ‘Trouble Brewing’ grouping teleport.
Alternatively, you can use a charter ship as well.
Cave Horror Gear Setup

Since Cave Horrors attack with a magical-based melee attack, you should always be wearing armour with high magic defense such as d’hide, Karils, and so forth.
Alternatively, you can also opt for prayer-boosting armor such as proselyte. When using this strategy, you do not need to use a Witchwood icon as your protect from melee will also negate their special attack.
Ranged Gear Setup

Are Cave Horror Tasks Worth It?
Cave Horrors tasks are very much worth it!

You can also use a cannon on this task, who would ever skip it?
