targeting monsters that offer high-value unique drops and consistent raw wealth. By prioritizing these specific Slayer tasks, you can transform the Slayer skill into your primary source of income while maintaining steady combat progress. This OSRS guide will break down the elite tier of money-making tasks, beginning with the Demonic Gorilla and the high-level strategy of the Alchemical Hydra. We will explore the “AFK” wealth of Brutal Black Dragon and the consistent alchable income of Gargoyle, finishing with the high-speed profit of Greater Nechryaels.
Demonic Gorillas
Demonic Gorillas are high-level monsters found in the Crash Site Cavern after completing the Monkey Madness II quest. They are widely considered one of the best Slayer tasks for profit due to their signature drop, the Zenyte shard, which is currently valued at approximately 16.8M GP.
Recommended Gear
Because they switch prayers, you must bring at least two combat styles (typically Melee and Ranged).
- Melee Weapon:
Emberlight is highly recommended as it specialized for demons. - Ranged Weapon:
Scorching bow or 
Toxic blowpipe are the most common choices. - Armor: Use
Slayer helmet (i) on task. For body and legs, 
Torva / 
Masori is best-in-slot.
Alchemical Hydra
Alchemical Hydra is a level 95 Slayer boss found in the Karuulm Slayer Dungeon. It is one of the most consistent money-makers in the game, famous for dropping the Hydra’s claw (62M GP) used to make the Dragon hunter lance.
Recommended Gear
- Main Weapon:
Twisted Bow is best-in-slot. Toxic Blowpipe or 
Bow of Faerdhinen are top-tier alternatives. For melee, use the 
Dragon hunter lance on stab. - Slayer Helmet (i): Essential for the 15% damage/accuracy boost.
- Spec Weapons:
Zaryte Crossbow (for Ruby bolt procs) or 
Dragon Claws to speed up phases.
Brutal Black Dragon
Brutal Black Dragons are powerful variants of black dragons found within the Catacombs of Kourend. They are widely popular among high-level players as a highly profitable “AFK” (low-effort) task that offers consistent gold and excellent Ranged experience. Reliable income of 800k to 1.6M+ GP/hr depending on gear and kill speed.
Recommended Gear
Ranged is the most efficient method due to the ability to ignore their melee damage from a distance.
- Top-tier Weapon: Twisted bow is the absolute best for DPS.
- Alternative BiS:
Dragon hunter crossbow (DHCB) paired with a 
Dragonfire ward. - Budget Gear:
Rune crossbow or 
Hunters’ sunlight crossbow. - Armor: Use Slayer helmet (i) if on task. For the body and legs, Masori, or
Blessed dragonhide are preferred for high accuracy.
Gargoyle
Gargoyles are iconic mid-to-high level Slayer monsters found on the top floor and in the basement of the Slayer Tower. They are famous for being a “money printer” task due to their consistent raw GP and high-alchable drops, making them a favorite for both main accounts and Ironmen. Highly consistent at roughly 600k – 1M GP/hr
Recommended Gear
- Best Weapon: They are weak to Crush attacks. The
Inquisitor’s mace, 
Abyssal bludgeon, or the budget-friendly 
Zombie axe are top choices. - Armor: Use a
Guthan’s set switch to heal off them, allowing you to stay for an entire task without banking.
Greater Nechryael
Greater Nechryaels are the high-level, multi-combat variants of Nechryaels, exclusively found in the Catacombs of Kourend, Iorwerth Dungeon, and Wilderness Slayer Cave. They are considered one of the best Slayer tasks in the game because they offer some of the highest experience rates alongside significant profit. Average profit is approximately 450K GP/hr. The task is famously “self-sustaining” as the alchable drops and runes typically pay for all supply costs.
Recommended Gear
- Best Weapon: The
Kodai wand and 
Elidinis’ ward (f) are considered the absolute best-in-slot (BiS) combination for Greater Nechryaels because they maximize Magic damage percentage, which is far more important than accuracy for this task. - Budget Weapon: The
Ancient Sceptre and 
Book of Darkness is currently the best overall budget choice for bursting/barraging. - Armor: Use Slayer helmet (i) if on task.
Final Thoughts
Focusing your Slayer journey on these five tasks ensures that your bank value grows alongside your experience bar. While some tasks like Demonic Gorillas require high concentration and “prayer flicking,” others like Gargoyles allow for a more relaxed playstyle while still generating significant revenue. Always remember to use your Slayer points to block slow, low-profit tasks so you can encounter these “money makers” as frequently as possible.
