OSRS Greater Demon Slayer Guide: Best Gear, Locations & Bosses (2026)

If you have been grinding through Old School RuneScape, chances are you have rolled a fair share of Greater Demon tasks. They are a core part of Slayer progression and a solid way to build XP.
Greater demons are a staple Slayer task in Old School RuneScape. They offer a reliable way to build combat and Slayer XP. Moreover, they are frequently challenged in the Catacombs of Kourend, where players can multitask by farming dark totem pieces from the surrounding creatures.
This OSRS Greater Demon Slayer guide provides everything you need to gear up and handle tougher encounters so you can clear your tasks efficiently.

OSRS Greater Demon Slayer: Choose Your Weapon
When you face Greater Demons, try to focus on their weakness. Since they rely entirely on melee attacks, you have two easy options: Tank the damage with high-defense gear like Justiciar armour or Barrows armour or simply use the Protect from Melee prayer and deal with them safely.

Combat Methods for Greater Demon Slayer
- Melee: Your strongest option is using Demonbane weapons. The classic Arclight already hits extremely hard against demons. However, upgrading to Emberlight takes things even further.
- Ranged: Skip the Blowpipe here. Scorching Bow is currently far superior for demon tasks. When combined with high Ranged Strength gear, it allows you to clear kills incredibly fast.
- Magic: Magic is a surprisingly effective approach if you lean into elemental weaknesses. Using a Purging Staff alongside the Dark Demonbane spell and applying Mark of Darkness makes for a powerful setup that can quickly wipe out Greater Demons.
Pro-tip: While the Toxic Blowpipe is a great general weapon, Greater Demons have a relatively high ranged defense. Because of this, the Scorching Bow vastly outperforms the Blowpipe here due to its passive demonbane effect. it increases your max hit and accuracy by 30% against demonic creatures.

Where to Kill Greater Demons in OSRS
Where you choose to kill them largely depends on your goal. If you want a relaxed grind, plan to use a Dwarf multicannon for faster kills.
AFK at the Catacombs of Kourend
If you want a laid-back grind, this is the go-to spot. Equip Proselyte armour, activate Protect from Melee and let the demons stack on you in multi-combat. It is very relaxed. You will passively collect Ancient shards for charging your Arclight, along with valuable Dark Totem pieces.
Cannoning in the Karuulm Slayer Dungeon
For faster task completion, bring a Dwarf multicannon. Make sure you wear Boots of stone or Brimstone boots to handle the heat damage. Place your cannon in the center. Then safespot from the corridor to rack up quick kills and XP.

Chasm of Fire & Isle of Souls
These are great single-combat alternatives. You can safely use a cannon and take advantage of safespots (like the pillars near the lift in the Chasm) to avoid damage entirely while maintaining steady kills. In my experience, cannoning in Chasm of Fire is the best balance of XP and AFK.
Wilderness Slayer Cave (High Risk, High Reward)
If you are chasing profit, head into the Wilderness Slayer Cave. Use a Burning amulet to teleport near the Chaos Temple, then run northeast. There is an easy safespot near the entrance behind stalagmites. Since it is multi-combat, always watch for PKers. However, the extra loot, including blighted supplies and Larran’s keys, makes the risk worthwhile.
Let’s be honest: the Wilderness Slayer Cave is a PKer hotspot in 2026. If you are going there, I highly recommend bringing a Royal Seed Pod as your one-click teleport. During my last run, I was jumped by a three-man team because I was parked in the stalagmite safespot near the entrance
Pro-tip: Try to keep your risk low while taking a task from Krystilia. Stick to budget-friendly gear like Black d’hide armour and pair it with weapons such as the Webweaver Bow or even a Rune crossbow. This setup lets you stay effective.

Spicing Things Up with Bossing
If regular Greater Demons feel repetitive, you can switch things up by taking on bosses that also count toward your Greater Demon Slayer.
Fight Tormented Demons
A hot topic in the community right now, Tormented Demons offer high-value drops like Synapses, which are used to craft top-tier weapons such as Emberlight and the Scorching Bow. If they feel too tanky with weaker gear, try to upgrade to Emberlight or use an Abyssal dagger alongside Demonbane spells.
Slaying K’ril Tsutsaroth
The Zamorak boss in the God Wars Dungeon turns your task into a serious money-maker. Using a Scorching Bow combined with Blood Barrage allows for extended trips, with many players comfortably reaching 20–30 kills per run.
Taking Down Skotizo
Those Dark Totems you have been collecting in the Catacombs finally pay off here. Fight Skotizo and it counts toward your task. This gives you a strong damage boost.

Your Slaying Strategy!
Completing an OSRS Greater Demon Slayer task is a core part of progression that you can tailor entirely to your playstyle. In general, there is no difference in how you face the demons. You can use any of the methods discussed in this article. The approach is entirely up to you!
