Fast Demonic Gorilla Kills with Low-Cost Gear in OSRS (2025 Guide)
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 cheap OSRS GP 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
Boots: Pegasian Boots or Blessed D’hide Boots
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 Melee and Ranged styles when the gorillas change their protection prayers.
Understanding the Fight
Demonic Gorillas use all three combat styles—Melee, Magic, and Ranged—and can switch between them depending on your actions. They also use protective prayers similar to players. Here’s what to expect:
Every 50 damage you deal, the gorilla changes its protection prayer.
If it’s protecting from Melee, switch to Ranged.
If it’s protecting from Ranged, switch back to Melee.
Always watch their attack animations—they change weapons visually depending on whether they’re using Magic, Range, or Melee.
They occasionally throw large boulders in a straight line. When you see a shadow appear beneath you, move at least one tile away to avoid massive damage.
The key to success is staying alert: switch prayers, swap combat styles quickly, and keep moving when necessary.
Combat Strategy
Start with Melee using Arclight and activate Piety.
When the gorilla switches to Protect from Melee, instantly swap to your Ranged setup and turn on Rigour.
Keep track of your prayer points—Demonic Gorillas hit hard if you drop your protection prayers even for a second.
Avoid boulders by staying mobile. This is one of the most common mistakes new players make.
Use High Alch on rune drops and alchables to keep inventory space free.
Once you get the rhythm down, you can consistently chain kills without banking for long periods.
Profit Potential
Demonic Gorillas are best known for dropping Zenyte Shards, worth around 16 million GP each on the Grand Exchange (as of 2025). While these are rare drops, they’re the main reason this method averages 4–5M GP per hour over time.
Other profitable drops include:
Rune and Dragon items (great for High Alch)
Ballista components
Noted supplies like runes and herbs
On average, a dedicated player can expect a Zenyte roughly every 10–12 hours of killing, but the steady stream of smaller drops keeps profits high even without one.
Final Tips
Learn to predict their prayer changes—timing your switches saves seconds and food.
Arclight charges are essential. Replenish them using Ancient Shards from the Catacombs of Kourend.
Stay calm under pressure—panicking leads to prayer mistakes and deaths.
If you’re new, practice on Tortured Gorillas first—they behave similarly but hit less hard.
Conclusion
With some practice and a smart setup, Demonic Gorillas can become one of your most consistent and rewarding money-makers in Old School RuneScape. You don’t need max gear or stats—just focus, timing, and proper gear switching. Master this rotation, and you’ll soon be stacking millions in OSRS GP every hour.
Good luck, legends—and happy hunting!
