If you're looking for a monster that's both challenging and incredibly profitable, look no further than Demonic Gorillas. These fierce creatures are among the most lucrative mid- to high-level money-makers in Old School RuneScape. With the right strategy and some affordable gear, you can comfortably pull in 4-5 million RuneScape gold per hour-even without maxed stats or expensive items.

In this guide, we'll cover everything you need to know: the requirements, how to get there, recommended setups, combat strategy, and tips to maximize your profits while minimizing risk.

Unlocking Demonic Gorillas

Before you can face these beasts, you must complete the quest Monkey Madness II. This is a lengthy and challenging Grandmaster quest that takes you through a series of dangerous encounters. However, it's absolutely worth it-not only for the experience and rewards but because it unlocks access to Demonic Gorillas, one of the best money-makers in the game.

Recommended Stats Before Starting:

Attack / Strength / Defence: 80+

Ranged: 80+

Prayer: 70+ (for Piety, Rigour, and protection prayers)

Hitpoints: 80+ is helpful for survivability

While you can technically fight them with lower stats, these levels ensure efficient kills and minimize wasted supplies.

How to Get There

After completing Monkey Madness II, you'll gain access to the Crash Site Cavern, located just north of the Tree Gnome Stronghold. This is where you'll find most Demonic Gorillas.

To reach the cavern quickly:

Use a Spirit Tree teleport to the Tree Gnome Stronghold, then run north.

Alternatively, use a Royal Seed Pod to teleport close by.

Always carry a one-click teleport (like a Seed Pod or Teleport Tab) for emergency escapes-Demonic Gorillas can hit very hard if you make a mistake.

Gear Setup (Low to Mid-Tier Options)

You don't need high-end gear like the Scythe of Vitur or Armadyl crossbow to make serious money here. A solid, affordable setup is more than enough.

Melee Setup

Weapon: Arclight (best-in-slot for demon-type monsters thanks to its 70% accuracy and damage boost)

Alternatives: Osmumten's Fang, Abyssal Whip

Body/Legs: Elite Void Melee Set

Helmet: Void Melee Helm or Fighter Hat

Off-hand: Dragon Defender or Avernic Defender

Cape: Fire Cape or Ardougne Cloak 4

Boots: Dragon Boots or Guardian Boots

Ranged Setup

Weapon: Toxic Blowpipe (fast, accurate, and budget-friendly)

Ammunition: Addy or Dragon Darts

Helmet: Void Ranged Helm

Cape: Assembler or Ava's Accumulator

Body/Legs: Void Ranged Set

Gloves: Barrows' Gloves

Inventory Setup

Super Combat Potion and Ranging Potion

Prayer Potions (bring 4-6, depending on kill speed)

High-healing food like Sharks or Karambwans

1-click teleport (Royal Seed Pod or Teleport Tab)

Runes for High Alchemy (to free up inventory space)

This setup lets you efficiently switch between cheap RS gold Melee and Ranged styles when the gorillas change their protection prayers.
