I’ve spent hundreds of hours grinding Demonic Gorillas since their release, and I’m here to tell you that these monkey-men are absolutely worth learning. While they might seem intimidating at first, once you master their mechanics, you’ll have access to one of the most reliable money makers in the game – plus the only source of those coveted Zenyte shards worth over 20M GP each.
Demonic Gorillas are level 275 monsters introduced with the Monkey Madness II quest, and they’re essentially the gateway to high-level PvM in OSRS. Think of them as the final boss of mid-game content – they’ll test everything you’ve learned about prayer switching, gear swapping, and positioning.
What makes them special? They’re the only monsters that drop both Zenyte shards (1/300 drop rate) and ballista parts. With Zenyte currently sitting at around 20.5M GP, even a single shard can make your entire session profitable.
Honestly? I was terrified of these guys when I first started. My first trip ended with me teleporting out after 3 kills, completely overwhelmed by the constant prayer switching. But something kept me coming back – maybe it was the thrill of the challenge, or perhaps I was just tired of seeing everyone else sporting those shiny Zenyte amulets.
After about 50 hours of practice, everything clicked. The prayer switching became muscle memory, the gear swaps felt natural, and suddenly I was pulling in consistent profits. There’s nothing quite like that moment when a Zenyte shard finally drops after 300 kills – the rush is absolutely unreal.
Before you even think about tackling these beasts, you’ll need:
Quest Requirements:
Skill Requirements (no boosts allowed):
Recommended Combat Stats:
Trust me, don’t try this with low stats. I learned that lesson the hard way with a 2M GP gear loss on my first attempt.
This is where most guides fall short – they give you the basics but miss the crucial details that separate 30 KPH players from 80 KPH players.
Demonic Gorillas follow a simple but critical pattern: after three missed hits, they switch attack styles. Here’s the kicker – those “missed hits” include attacks that you prayer flick correctly! So if you’re praying against their magic attack and it hits a 0, that counts toward the three-hit counter.
Pro tip: I count out loud when I’m grinding. “One, two, three” – sounds silly but it works.
This is where things get interesting. After taking 70+ damage from styles they’re not protecting against, they’ll switch their protection prayer. This means you need to be constantly switching between at least two combat styles.
Most players use Melee + Ranged because:
When they’re using Magic or Ranged, they’ll occasionally do a chest-beating animation and drop a boulder on your position. Move one tile immediately or you’ll take 33% of your health as damage. This attack doesn’t count toward the three-hit rule, which can mess up your counting if you’re not paying attention.
I’ve tested every setup imaginable, from budget ironman gear to maxed main setups. Here are the ones that consistently perform:
Perfect for learning or ironmen:
This is what I use for most of my grinding:
For those 80+ KPH sessions:
Let me walk you through your first successful kill:
Your first few kills will be messy. That’s normal. I died probably 20 times before I got consistent.
This technique took me from 45 KPH to 65 KPH almost overnight:
When a Demonic Gorilla switches from Magic or Ranged, move one tile away from it:
This works 83% of the time and completely eliminates guesswork.
Most guides tell you to switch gear, but they don’t explain the timing. Here’s what I do:
This minimizes time spent not dealing damage.
For extended trips, prayer flicking is essential. Here’s my method:
This saves 30-40% prayer points and extends your trips significantly.
Let me break down the numbers based on my recent 1000-kill test:
Average Kill Value: 88,562 GP Without Zenyte Shard: 20,954 GP per kill With Zenyte Shard: 20.5M+ GP bonus
Hourly Rates (70 KPH average):
Supply Costs:
The variance is real. Some hours I make 800K, others I hit a Zenyte shard and make 20M. That’s part of the excitement.
I used to switch prayers every time I saw a different animation. Wrong! Only switch after three zeros.
Fix: Count deliberately. Don’t let the fast-paced combat rush you.
Switching gear too early or too late kills your DPS.
Fix: Wait for the visual confirmation of their protection prayer before switching.
That boulder attack hits HARD. I’ve lost countless KC to ignoring it.
Fix: Make movement automatic. The second you see the chest-beating, move.
Running out of prayer potions mid-fight is brutal.
Fix: Always bring one extra prayer potion than you think you need. Trust me.
As an ironman player myself, here are some tips that most guides ignore:
The May 2024 update brought some important changes:
These changes have made Demonic Gorillas slightly more profitable but also a bit more challenging. The meta has shifted toward using Emberlight + Scorching Bow for max efficiency, though the Arclight + Blowpipe combo remains the most accessible.
If you’re struggling with the mechanics, here’s my recommended progression:
Don’t rush this progression. I spent 2 weeks just practicing prayer flicking before attempting my first real trip.
A: I use 3-4 divine prayer potions per hour depending on my flicking consistency.
A: Absolutely! Even at 1.4M GP/hour baseline, it’s better than most mid-game money makers.
A: I wouldn’t recommend it. Demonic Gorillas have high magic defense, and Magic is expensive to train.
A: Play on low-detail worlds, and consider using the RuneLite Demonic Gorilla plugin to help track attack patterns.
A: Definitely! The Slayer helm bonus and increased damage make a significant difference in KPH.
Demonic Gorillas represent everything I love about OSRS – challenging mechanics, rewarding gameplay, and that incredible feeling when everything just clicks. They’re not easy, but that’s what makes them so satisfying.
Whether you’re here for the money, the PvM practice, or just want to craft some Zenyte jewelry, mastering these monkeys will make you a better player overall. The skills you learn here – prayer switching, gear swapping, pattern recognition – will carry over to every other boss in the game.
So grab your Arclight, stock up on prayer potions, and get out there. The Zenyte shards are waiting, and honestly? There’s nothing quite like the feeling of that purple drop finally appearing after hours of grinding.
Happy hunting, and may your Zenyte drop rates ever be in your favor!
