Best Greater Demon Cannon Spot OSRS Guide for Efficient Slayer Tasks

Greater Demons are a staple Slayer task in Old School RuneScape (OSRS), known for their rune full helm and hard clue scroll drops. For players looking to maximize experience rates and efficiency, using a Dwarf Multicannon at the right spot is a game-changer. This guide dives into the best cannon spots for Greater Demons, focusing on setup, strategies, and tips to optimize your Slayer tasks. Whether you’re a mid-level player or a seasoned veteran, this post will help you slay Greater Demons with ease.

Greater Demons, with combat levels of 100-104 and 115-120 hitpoints, are relatively tanky but have low defense, making them ideal for cannoning. The Dwarf Multicannon boosts kill speed significantly, especially in multicombat areas, allowing for AFK training and faster task completion. Here’s why cannoning is effective:

• High XP Rates: Cannons deal consistent damage, increasing Slayer and combat XP per hour.
• AFK Potential: Multicombat areas let you set up and relax while the cannon does the work.
• Drop Collection: Faster kills mean quicker access to valuable drops like rune full helms.

Top Greater Demon Cannon Spots in OSRS

Not all Greater Demon locations are cannon-friendly. Below, we explore the best spots where you can place a cannon for maximum efficiency, based on accessibility, safety, and kill speed.

Chasm of Fire: The Premier Cannon Spot

The Chasm of Fire, located in Shayzien, is the go-to spot for cannoning Greater Demons due to its Slayer-only area and compact layout. With 17 spawns split into two groups (8 and 9), it’s perfect for cannon placement.

• Access: Use Fairy Ring code DJR or teleport to Shayzien and run northwest.
• Setup: Place the cannon near the central pillars on the middle floor to hit multiple demons. Safespot using the pillars for Ranged or Magic.
• Pros: Single-combat but cannonable, fast kills, easy access.
• Cons: Requires a Slayer task, slightly spread-out spawns.

Tip: Use Granite Cannonballs (crafted with Granite Dust) for a max hit of 35 instead of 30, boosting efficiency.

Wilderness Slayer Cave: High Risk, High Reward

The Wilderness Slayer Cave is a multicombat area with enhanced loot tables, making it a lucrative cannon spot for Greater Demons. However, it’s a PvP zone, so caution is advised.

• Access: Teleport with a Games Necklace to Corporeal Beast or use a Wilderness Crabs Teleport.
• Setup: Place the cannon near the stalagmites at the entrance to hit multiple demons. Safespot behind stalagmites to avoid melee damage.
• Pros: Multicombat, cannon hits multiple targets, unique drops like blighted items.
• Cons: High PK risk, long run without teleports.

Tip: Bring a Royal Seed Pod or Amulet of Glory for quick escapes and a Looting Bag to store drops. Only bring gear you’re willing to lose.

Isle of Souls Dungeon: Underrated and Quiet

The Isle of Souls Dungeon is a less crowded spot with 8 Greater Demon spawns, ideal for players seeking a low-traffic cannoning area.

• Access: Teleport to Soul Wars or use a Kharedst’s Memoirs teleport and run to the dungeon.
• Setup: Place the cannon near the stairs and safespot behind the fungus to hit multiple demons.
• Pros: Single-combat but cannonable, less competition, safespot available.
• Cons: Far from teleports, spread-out spawns reduce cannon efficiency.

Tip: Combine with Protect from Melee to minimize damage if not safespotting.

Gear and Inventory Setup for Cannoning

Your gear and inventory depend on your combat style and budget. Below is a recommended setup for Ranged, which is optimal due to Greater Demons’ weakness to bolts.

Recommended Gear

Slot	Item	Alternative (Budget)
Head	Slayer Helmet (i)	Black Mask
Cape	Ava’s Accumulator	Obsidian Cape
Body	Armadyl Chestplate	Black D’hide Body
Legs	Armadyl Chainskirt	Black D’hide Chaps
Weapon	Rune Crossbow	Magic Shortbow
Ammo	Diamond Bolts (e)	Broad Bolts

Note: Use a Ferocious Ring in the Wilderness for extra damage or a Ring of Wealth for better drop luck.

Inventory Setup

• Dwarf Multicannon (all parts)
• 1000-1500 Cannonballs (adjust based on task size)
• Prayer Potions (4-6) for Protect from Melee
• Food (Sharks or better) for emergencies
• Teleport (e.g., Royal Seed Pod, Glory) for quick exits
• Looting Bag (Wilderness only)
• Ranging Potion for accuracy boost

Tip: For AFK in the Catacombs, bring Proselyte Armor and extra Prayer Potions to sustain Protect from Melee.

Strategies for Efficient Cannoning

To get the most out of your cannon, follow these strategies tailored to Greater Demon tasks.

Safespotting with the Cannon

In all recommended spots, safespots are available to avoid taking damage. Use pillars (Chasm of Fire), stalagmites (Wilderness Slayer Cave), or fungus (Isle of Souls) to stay out of melee range while your cannon fires. This is especially useful for low-defense accounts or ironmen.

Maximizing Cannon Efficiency

• Positioning: Place the cannon in the center of demon spawns to hit as many as possible.
• Reload Timing: Reload every 15-20 kills to avoid downtime.
• Granite Cannonballs: Use for 16.7% higher damage output.

AFK Training in Multicombat Areas

In the Catacombs of Kourend or Wilderness Slayer Cave, you can AFK with Protect from Melee and Proselyte Armor. The cannon will kill demons while you collect ancient shards or dark totem pieces (Catacombs) or wilderness-specific loot. Reset aggression every 10 minutes by running out and back.

Tips and Tricks for Greater Demon Slayer Tasks

Beyond cannoning, here are additional tips to enhance your Greater Demon tasks.

Loot and Drops

Greater Demons drop rune full helms (worth ~20k), hard clue scrolls, and in the Catacombs, ancient shards and dark totem pieces for Skotizo. In the Wilderness, expect blighted items and teleport tablets. Use an Ash Sanctifier (Kourend Diary) to auto-scatter ashes for Prayer XP.

Alternative Monsters

If assigned Greater Demons, you can kill K’ril Tsutsaroth (God Wars Dungeon) or Skotizo (Catacombs) for the task. Skotizo offers 1200 Slayer XP per kill and guaranteed clue scrolls but requires a dark totem. K’ril is tougher but drops high-value items.

Managing Wilderness Risks

In the Wilderness Slayer Cave, avoid peak hours and world-hop if PKers appear. Use Protect Item prayer and keep your risk low (e.g., only cannon, crossbow, and bolts).

Conclusion

Cannoning Greater Demons in OSRS is a fantastic way to breeze through Slayer tasks while earning decent XP and loot. The Chasm of Fire stands out for its accessibility and safety, while the Wilderness Slayer Cave offers high rewards for risk-takers. The Isle of Souls is a solid backup for quieter sessions. With the right gear, cannon setup, and safespot, you’ll crush these tasks efficiently. Grab your cannon, load up those cannonballs, and start slaying!
