OSRS Black Demons Slayer Guide

Black Demons are a formidable Slayer task in Old School RuneScape (OSRS), known for their high combat level and challenging mechanics. Assigned at combat level 80 by Slayer masters like Chaeldar, Konar, Nieve, Duradel, and Krystilia, these demons offer decent experience but require careful preparation due to their high Hitpoints and melee attacks. This guide covers everything you need to know to tackle Black Demons efficiently, including locations, gear setups, strategies, and tips for maximizing XP and profit.

Black Demons are large, aggressive demons found in various dungeons across Gielinor. With combat levels of 172, 178, or 184, they boast 157–170 Hitpoints and a max hit of 16–17 with melee. Despite their high offensive stats, their Defence is relatively low, making them vulnerable to specific attack styles.

Key Weaknesses

• Demonbane Weapons: Weapons like Arclight, Silverlight, and Darklight deal bonus damage.
• Magic Attacks: They are particularly weak to water spells and other magical attacks.
• Ranged Attacks: Safespotting with Ranged is effective in most locations.

Slayer Requirements

Black Demons require 80 combat to be assigned as a Slayer task, with no specific Slayer level needed. However, they can be daunting for players under 100 combat due to their high Hitpoints and damage output. Low-level players may find them slow and resource-intensive, often making them a recommended block task for those under 90 combat.

Best Locations for Black Demons

Choosing the right location is crucial for efficiency. Black Demons spawn in several dungeons, each with unique advantages and challenges. Below are the top spots for Slayer tasks.

Taverley Dungeon

The Taverley Dungeon is a prime location for cannon users due to its clustered spawns (11 demons). Access requires 70 Agility for the pipe shortcut or a Dusty Key for the longer route via the Blue Dragon Lair. This spot is ideal for high XP rates, offering 19–35K Slayer XP per hour depending on your stats.

Catacombs of Kourend

The Catacombs of Kourend offer a multicombat area with four Black Demon spawns, perfect for AFK melee training. Use Protect from Melee and prayer-boosting gear like Proselyte. You can’t use a cannon here, but the chance to drop Ancient Shards and Dark Totem pieces adds value. Teleport to Kourend Castle (60% Arceuus Favour) or use Fairy Ring code CIS for quick access.

Chasm of Fire

Located on Zeah, the Chasm of Fire (bottom level) is a Slayer-only area with cannonable spawns. It’s less densely populated than Taverley but still effective. Use Fairy Ring code DJR or Kharedst’s Memoirs for fast travel. This spot is great for players without 70 Agility.

Wilderness Locations

Black Demons in the Wilderness Slayer Cave and Edgeville Dungeon (both under 30 Wilderness) offer unique drop tables, especially on Krystilia tasks. However, the risk of PKers makes these spots less safe. The Wilderness Slayer Cave is multicombat with four spawns, while Edgeville Dungeon has three, making it quieter. Bring only what you’re willing to lose and use RuneLite’s player notifications to avoid PKers.

Brimhaven Dungeon

Brimhaven Dungeon has four spawns but is less popular due to its remote location and 875-coin entry fee (waived after Hard Karamja Tasks). It’s cannonable and safespotable but less efficient than Taverley or Chasm of Fire. Use Tai Bwo Wannai teleport or Fairy Ring code CKR to get there.

Recommended Gear and Inventory

Your gear and inventory setup will depend on your combat style and location. Below are optimized setups for melee, Ranged, and Magic, focusing on prayer-boosting gear to sustain Protect from Melee.

Melee Setup

Melee is viable with Protect from Melee and prayer-boosting gear. Avoid tank gear, as Black Demons hit hard through high Defence.

Slot	Item
Head	Slayer Helmet (i) or Black Mask
Neck	Amulet of Fury or Glory
Body	Proselyte Hauberk
Legs	Proselyte Cuisse
Weapon	Arclight (if available) or Abyssal Whip
Shield	Dragon Defender
Cape	Ardougne Cloak or Fire Cape

Ranged Setup

Ranged is ideal for safespotting, especially in Taverley or Chasm of Fire. Use a crossbow or toxic blowpipe for high DPS.

• Head: Slayer Helmet (i)
• Neck: Amulet of Fury
• Body: Black D’hide Body
• Legs: Black D’hide Chaps
• Weapon: Toxic Blowpipe or Rune Crossbow
• Ammo: Amethyst Darts or Diamond Bolts (e)
• Cape: Ava’s Accumulator

Magic Setup

Magic is effective due to Black Demons’ weakness to water spells. Use safespots to minimize damage.

• Head: Slayer Helmet (i)
• Neck: Occult Necklace
• Body: Mystic Robe Top
• Legs: Mystic Robe Bottom
• Weapon: Trident of the Seas or Iban’s Staff
• Spell: Water Surge or Fire Bolt (with Tome of Fire)
• Cape: Imbued God Cape

Inventory Setup

• 4–6 Prayer Potions
• 10–15 High-healing Food (Monkfish or Sharks)
• 1–2 Super Restore Potions (for summoning familiars)
• Holy Wrench (boosts prayer restoration)
• Soul Bearer (for ensouled heads)
• Teleport Runes or Tablets (for banking)
• Cannonballs (if cannoning)

Strategies for Efficient Kills

Maximizing XP and minimizing costs requires the right strategy. Here are the best approaches for Black Demon Slayer tasks.

Cannoning for Fast XP

Using a Dwarf Multicannon in Taverley Dungeon or Chasm of Fire yields the fastest XP (up to 35K Slayer XP per hour with max melee and Piety). Set the cannon in the center of the Black Demon room, pray Protect from Melee, and auto-retaliate. This method is costly, so bring plenty of cannonballs and prayer potions.

Safespotting with Ranged or Magic

Safespots are available in all Black Demon locations, making Ranged or Magic ideal for low-damage kills. In Taverley Dungeon, use the stalagmites near the spawns. In Catacombs, stand under the arch dividing the demon area. Safespotting reduces prayer potion usage but is slower than cannoning.

AFK Melee in Catacombs

For a low-effort approach, use the Catacombs of Kourend with Proselyte armor and Protect from Melee. Auto-retaliate and occasionally sip prayer potions. This method is great for multitasking but offers slower XP (around 19–23K per hour).

Demonic Gorillas as an Alternative

After completing Monkey Madness II, you can kill Demonic Gorillas instead of Black Demons for a Slayer task (except Krystilia or Konar tasks). Found in the Crash Site Cavern, they drop Zenyte Shards (1/300 rate, worth ~9M) and high-value alchables, making them far more profitable. However, they require switching combat styles due to their protection prayers, so bring both melee and Ranged gear.

Tips for Profit and Efficiency

While Black Demons have a lackluster drop table (average kill worth ~2K GP, 3.4K on Konar tasks, 4K on Krystilia tasks), you can optimize your task for profit and efficiency with these tips.

Notable Drops

• Infernal Ashes: 100% drop, worth ~1K each. Use with Demonic Offering (84 Magic) for 195 Prayer XP per ash.
• Ensouled Demon Head: 1/35 drop, can be reanimated for Prayer XP.
• Clue Scroll (Hard): 1/128 drop, increases to 1/64 with Ring of Wealth (i) in Wilderness.
• Rune Chainbody/Med Helm: 1/128 drop, decent alch value.
• Ancient Shard/Dark Totem Pieces: Catacombs-exclusive, used for Skotizo boss fight.

Maximizing Profit

• Use a Ring of Wealth (i) in Wilderness for better clue scroll odds.
• Bring a Soul Bearer to bank ensouled heads instantly.
• Alch low-value drops like Black Sword or Mithril Kiteshield on-site.
• Consider Demonic Gorillas for high-profit potential.

Efficiency Tips

• Extend tasks with “It’s dark in here” unlock (100 Slayer points) for 200–250 kills.
• Use prayer-boosting gear to reduce potion costs.
• Block Black Demons if under 90 combat, as they’re slow and unprofitable.
• In Wilderness, limit risk by bringing only 3–4 valuable items.

Black Demons are a solid Slayer task for mid-to-high-level players, offering decent XP and moderate rewards when approached strategically. Whether you cannon in Taverley, AFK in Catacombs, or chase profits with Demonic Gorillas, this guide equips you to handle the task efficiently. Good luck, and happy Slaying!
