OSRS Greater Demon Cannon Spot: Best Locations and Strategies for Slayer Tasks


If you’re an Old School RuneScape (OSRS) player tackling a Greater Demon slayer task, finding the perfect cannon spot can make all the difference. Greater Demons are iconic monsters known for their rune full helm and hard clue scroll drops, and using a dwarf multicannon can significantly boost your experience rates and efficiency. In this guide, we’ll explore the best OSRS Greater Demon cannon spots, strategies to maximize your kills, and tips to optimize your slayer task. Whether you’re a seasoned player or just starting out, this blog post will help you dominate your Greater Demon tasks with ease.

Greater Demons are level 92 monsters with decent hitpoints (120) and a max hit of 10, making them a solid mid-tier slayer task. While their drop table isn’t the most lucrative, the ability to use a cannon in certain locations turns them into an excellent source of AFK slayer experience. Cannoning Greater Demons speeds up kill times, reduces the need for constant attention, and allows you to rack up XP while focusing on other tasks. Plus, with the right spot, you can take advantage of multicombat areas to hit multiple demons at once.

Benefits of Cannoning Greater Demons

  • Faster Kills: The cannon automates damage, cutting down task completion time.
  • AFK Potential: Pair it with prayer or safespots for a low-effort grind.
  • Higher XP Rates: More kills per hour mean better slayer and combat XP.
  • Multicombat Efficiency: In the right areas, the cannon targets multiple demons simultaneously.

Not all Greater Demon locations are cannon-friendly, so choosing the right spot is key. Below, we’ll break down the best places to set up your cannon, including their pros, cons, and how to get there.

Chasm of Fire: The Classic Cannon Spot

The Chasm of Fire, located northwest of Shayzien in Great Kourend, is one of the most popular cannon spots for Greater Demons. This dungeon has 17 Greater Demon spawns split across two areas (8 and 9 spawns), making it ideal for cannon use despite being a single-combat zone.

  • How to Get There: Use Fairy Ring code DJR, then head north to the entrance. Alternatively, teleport to Shayzien with the Memoirs book and run northwest.
  • Pros: Plenty of demons, safespots behind pillars, and no PKer risk.
  • Cons: Single-combat limits cannon efficiency slightly; requires a slayer task to attack.
  • Tip: Place your cannon near the center of the 9-spawn area to hit as many demons as possible.

Wilderness Slayer Cave: High Risk, High Reward

The Wilderness Slayer Cave, located in level 17-22 Wilderness, is a multicombat area with several Greater Demon spawns. This spot is perfect for cannoning due to its open layout and enhanced drop table, but beware of player killers (PKers).

  • How to Get There: Use a Wilderness Crabs teleport or run north from Ferox Enclave.
  • Pros: Multicombat allows the cannon to shred multiple demons; bonus Wilderness loot like blighted items.
  • Cons: PKer hotspot—bring only what you’re willing to lose.
  • Tip: Set up behind stalagmites for a partial safespot and keep an escape teleport handy.

Karuulm Slayer Dungeon: Elite Efficiency

The Karuulm Slayer Dungeon, beneath Mount Karuulm, offers a fantastic cannon spot for Greater Demons. With 10 spawns in a compact area, this location shines if you’ve completed the Elite Kourend & Kebos Diary for boot upgrades.

  • How to Get There: Teleport with Rada’s Blessing (best option) or use Fairy Ring code CIR and run north.
  • Pros: Multicombat, close spawn proximity, and no Wilderness risks.
  • Cons: Requires boots of stone or brimstone (unless Elite Diary is done).
  • Tip: Position the cannon at the room’s entrance to maximize its range across all spawns.

Optimal Gear and Inventory Setup for Cannoning

To make the most of your Greater Demon cannon spot, your gear and inventory need to balance offense, defense, and sustainability. Here’s a breakdown of what to bring.

Recommended Gear

Since Greater Demons primarily use melee attacks, prioritize prayer-boosting gear for Protect from Melee or high-defense armor if tanking.

Slot Budget Option Best-in-Slot Option
Head Proselyte Sallet Slayer Helmet (i)
Body Proselyte Hauberk Bandos Chestplate
Legs Proselyte Cuisse Bandos Tassets
Weapon Abyssal Whip Scythe of Vitur
Ammo Cannonballs (2000+) Granite Cannonballs

Inventory Setup

  • Cannon Essentials: Cannon base, stand, barrels, and cannonballs.
  • Prayer Support: 4-6 Prayer potions or Super restores.
  • Food: 5-10 Sharks or better for emergencies.
  • Teleport: Xeric’s Talisman or Glory for quick banking.
  • Optional: Looting bag (Wilderness) or alchs for rune full helms.

Strategies for Maximizing Cannon Efficiency

Setting up your cannon is only half the battle—using it effectively is what separates good slayers from great ones. Here are some strategies to get the most out of your Greater Demon task.

Positioning Your Cannon

Placement is critical. In multicombat areas like the Wilderness Slayer Cave or Karuulm Dungeon, position the cannon in the center of the spawn area to hit as many demons as possible. In single-combat zones like the Chasm of Fire, place it where it can target the densest cluster while you safespot or tank nearby.

Combining with Combat Styles

While the cannon does the heavy lifting, supplementing it with your own attacks boosts efficiency. Melee is ideal for close-range kills, but Ranged or Magic works wonders from safespots. For example:

Managing Aggro and Prayer

In multicombat areas, expect multiple demons to aggro you. Use Protect from Melee and sip prayer potions as needed. In the Catacombs of Kourend (non-cannonable but worth mentioning), you can AFK with prayer alone, but for cannon spots, keep an eye on your health and cannonball count.

Tips and Tricks for Greater Demon Slayer Tasks

Beyond the cannon, a few extra tricks can elevate your slayer game. Here’s how to fine-tune your approach.

Loot and Profit Tips

Greater Demons don’t drop much of value, but you can still turn a small profit:

  • Rune Full Helms: High-alch for 21k GP each.
  • Hard Clue Scrolls: Save these for a treasure trail session.
  • Wilderness Bonus: Blighted items or teleport tablets from the Slayer Cave.

Avoiding Common Mistakes

  • Overloading Cannonballs: Bring 2000-3000 max—more is overkill for most tasks.
  • Ignoring PKers: In the Wilderness, stay vigilant and bank often.
  • Skipping Safespots: Use them in single-combat areas to save food and potions.

Alternative Monsters for Greater Demon Tasks

If you’re tired of regular Greater Demons, consider these alternatives that count toward your task:

With the right cannon spot and strategy, Greater Demon slayer tasks in OSRS can be a breeze. The Chasm of Fire offers safety and consistency, the Wilderness Slayer Cave brings high-risk rewards, and the Karuulm Dungeon provides elite efficiency. Pair your cannon with smart gear, positioning, and a few pro tips, and you’ll be racking up slayer XP in no time. Happy slaying!
