OSRS Demonic Gorilla Guide

It's no secret that there are lots of scary foes in OSRS. However, in terms of looks alone, none might be as scary as the demonic gorillas in the game. Fighting these beasts isn't as easy as it seems as they're pretty powerful in their own right. This guide will teach you all there is to know about going up against them.

What Are OSRS Demonic Gorillas?

These are powerful monsters that you can find in the Crash Site Cavern. If you're doing the Monkey Madness II quest, you'll face off against two at once during the last part of the story. Once you finish the quest, you can fight more of them inside the dungeon.

The demonic gorillas have a combat level of 272. Killing them is good if you want to farm zenyte shards or ballista component drops. With maximum efficiency, you can get over 2,600,000 gold per hour when farming them for money.

Where To Fight Demonic Gorillas?



For starters, you'll first need to do the Monkey Madness II Quest to start being able to fight demonic gorillas. Not considering the quests requirements before it, the Monkey Madness II quest is tagged as a "very long" quest so you'll need to be patient with it. Additionally, the chance to fight the enemies comes way late into the quest.

Before anything else, prepare or complete the following:

Eventually, the quest will lead you into the Crash Site Cavern which will pit you against two demonic gorillas. You can find more of the monsters in the area once the quest is done. Below is a list of all known locations of demonic gorilla spawn points and there are a total of 28.

Demonic Gorilla Fight Overview

These are just basic enemies but why are they causing players so much trouble you ask? One of the reasons why is that they can use all three combat styles. They're also capable of using protection players.

The good thing is that the demonic gorilla doesn't change their combat style at random. It's initiated by a few conditions:

  1. If they take more than 50 damage, they'll switch their combat style to the one the player is currently using.
  2. They'll also change their combat style if they miss three hits using the current one they're using.


In that sense, you can predict which combat style the demonic gorilla is going to use. It's also worth noting that since they have a high magic defense, it's best to take them on either with a ranged or melee setup. In total, the demonic gorilla has four attacks:

  • Magic: You'll know that it's a magic attack when the enemy rears up and dangles its forelegs. It will then release a green orb from its attack,
  • Melee: A basic attack that sees the gorilla swiping down its claws at you.
  • Ranged: Another basic attack in which it will grab a small boulder to throw at you.
  • Boulder toss: In this attack, the gorilla will toss a boulder. Once the animation is completed, it will appear on top of you before dropping down. This does 33% of your health as damage if not dodged. This attack only happens when the gorilla is in its ranged or magic mode. It's worth noting that this attack won't count towards the miss count when it changes attack modes.

Tips For Fighting The Demonic Gorilla

With fight mechanics that are as confusing as this, it can be hard to understand how to beat the demonic gorilla. As such, here are a few key tips to keep in mind.

  1. Use Item Switches To Your Advantage - The demonic gorilla can switch up their protection prayers very often. That said, you shouldn't have too many item switches for your ranged or melee gear. Instead, focus on bringing offensive and protection prayers so that you can focus more on either dealing damage or taking it.
  2. Prayer Priority - During the fight, it's best to focus on using Protect from Magic and then Protect from Missiles or Melee. With the setup above, it's very likely that the demonic gorilla will switch to Protect from Magic mostly.


  1. Watch For The Cues - Aside from the conditions above, there are also a few cues you can check out to know which combat style the demonic gorilla is going to use next. You can listen in for a "Rhaaaaaa!" audio cue to know if the monster is switching styles.
  2. Utilize Special Items - If your combat level is high enough and if you have good enough equipment, you won't need to bring food for healing anymore. Use Saradomin godsword instead for healing. If the godsword isn't enough for healing, you can also use Guthan's set for more healing.
  3. Farm With A- Pair - There is one area in the Crash Site Cavern which can be used as a multicombat area so you can farm the monsters here with a team. The best strategy for duo fighting demonic gorillas is to have one player equip a full Dharok set at one HP. The other player tanks the demonic gorilla while the other deals damage. Thanks to Dharok's effect, the attacking player can deal maximum damage. If you're going to follow this strategy, take note of the following:
  • The player with the Dharok's set should never be close to the demonic gorilla.
  • The player assigned to tanking should use a crossbow to lure the demonic gorilla's from afar.
  • As with solo farming methods, you shouldn't bring too many item switches.
  • The player who's tanking should focus on building up their defense. The best set for this would be a full Guthan's set.
  1. Practice - With enough practice, you'll be able to take out the demonic gorilla quickly. The most important thing to do here is to somewhat manipulate the monsters into switching their combat style to something that's more beneficial for you.
