In Old School RuneScape (OSRS), Slayer remains one of the most rewarding skills in the game — both for experience and for OSRS GP. The profitability of Slayer tasks has always evolved with updates, new monsters, and changes to item value. In 2026, a combination of high-value rare drops, consistent valuable loot, and efficient task mechanics define the most profitable Slayer tasks.

This guide explores the top profitable tasks, why they excel, and how you can maximize your GP per hour and per task.

1. Abyssal Demons

Profit Potential: Very High

Level Requirement: 85 Slayer

Abyssal demons have been a staple of Slayer GP for years, and in 2026 they’re still one of the most consistent money-making tasks at higher levels.

Why they’re profitable:

Consistent rune and demon drops: Runes, dragon items (like dragon dagger and longsword), and various battle staves sell solidly on the Grand Exchange.

Abyssal bludgeon parts: These valuable drops can fetch high prices due to their use in creating the bludgeon weapon — still a high-demand item.

Abyssal heads: Toss in some Slayer reward points for boss tasks and adds incremental value.

Tips for efficiency:

Use an Abyssal bludgeon if you can — it speeds up kills and increases drop rates.

A safe, multi-style setup (magic for binding, melee for DPS) maximizes time per kill.

GP/H Estimate: 6–10m+ (with bludgeon parts included)

2. Skeleton Hellhounds

Profit Potential: High

Level Requirement: 80 Slayer

The introduction of skeleton hellhounds years back added a new lucrative task in the Slayer rotation. They remain at the top in 2026.

Why they’re profitable:

Bones & ashes: Big bones + dragon bones + ashes — good for training Firemaking and Prayer at the same time.

Clue scrolls: These drop frequently and can be a substantial side source of GP.

Tips for efficiency:

Bring a salve amulet (e) to boost damage.

Use an area with multiple spawns and minimal interference to chain kills quickly.

GP/H Estimate: 4–8m+

3. Cave Horrors

Profit Potential: Very High

Level Requirement: 80 Slayer (with cave entry unlocked at 50 combat if pre-required)

Cave horrors may not be as well known as abyssal demons, but they’re among the most profitable Slayer tasks in the game.

Why they’re profitable:

Mysterious emblem pieces: These drop consistently and are worth a lot on the Grand Exchange.

Bounty Hunter items: Additional valuable loot adds up quickly.

High drop value per hour compared to many other tasks.

Tips for efficiency:

Always bring a Black mask (i) for bonus damage.

They’re weak to ranged — an efficient ranged setup can drastically improve XP and GP rates.

GP/H Estimate: 10m+

4. Vorkath

Profit Potential: Elite (Subject to task assignment)

Level Requirement: 75 Slayer & Dragon Slayer II

Not a standard Slayer monster, but Vorkath remains one of the most profitable encounters when assigned through superior monster tasks. Its drops define elite GP rates in 2026.

Why it’s profitable:

High-value unique drops: Items like the Vorki pet, Draconic visage, and blue dragonhide bodies sell for massive amounts.

Consistent rare loot: Even average kills offer excellent value.

Tips for efficiency:

Prioritize safe, optimized gear to avoid deaths — losing supplies eats into profit quickly.

Master its mechanics (acid pools, fireballs, etc.) to maximize your kill speed.

GP/H Estimate: 50m+ (for skilled players)

5. Greater Demons

Profit Potential: Moderate–High

Level Requirement: 40 Slayer

Greater demons don’t sound exotic, but they remain a solid money-making Slayer task — especially at mid-levels.

Why they’re profitable:

Rune and gemstone drops: Add decent GP per hour.

Clue scrolls: Frequent clues increase value when sold.

Tips for efficiency:

Use high-accuracy gear to maximize kills per hour.

Slayer helmets with upgrades make the task quicker and more profitable.

GP/H Estimate: 2–5m+

6. Hydra

Profit Potential: Elite

Level Requirement: 95 Slayer

Hydra in the Karuulm Slayer Dungeon remains one of the best late-game money makers. Its drops are rare but expensive, and it rewards high-skill players.

Why they’re profitable:

Primal weapon pieces and crafting materials: Highly priced.

High-tier loot table: Includes valuable items that skyrocket GP.

Tips for efficiency:

Perfect your rotation — Hydra mechanics punish mistakes.

Use prayer potions and brews strategically to minimize downtime.

GP/H Estimate: 20–40m+ (for advanced players)

7. Thermonuclear Smoke Devils

Profit Potential: High

Level Requirement: 93 Slayer

Smoke Devils are a long-time favorite for high-level players seeking consistent GP.

Why they’re profitable:

Runite and adamantite bars: Sell well or are useful for crafting.

Smoke devil masks/statues: These can fetch a premium on the GE.

Tips for efficiency:

Efficient inventory rotation keeps kill speed high.

Bring teleport tablets or multiple stamina mixes to minimize downtime.

GP/H Estimate: 6–10m+

8. Dagannoth Kings

Profit Potential: Elite

Level Requirement: Varies by King (usually high combat + task unlock)

Dagannoth Kings offer a mix of experience and massive profit on task.

Why they’re profitable:

King drops: Including rare items worth tons of GP.

Runes & crafted items: Profit even on average kills.

Tips for efficiency:

Bring a reinforced team or use prayer boosts for faster kills.

Split the task into manageable chunks to keep focus high.

GP/H Estimate: 20–50m+

Tips to Maximize Slayer Profit in 2026

1. Use Slayer Helm Upgrades

Upgraded Slayer helmets boost accuracy and damage — boosting both XP and item drop rates.

2. Optimize Supplies

Buying supplies in bulk and managing inventory efficiently increases net profit.

3. Focus on Fast Tasks

Even if a task has great GP potential, slow kills might reduce overall GP/hour.

4. Master Rotation

Switch to the most profitable tasks you can handle efficiently — longer slower tasks often earn less per hour.

Final Thoughts

Slayer in 2026 still offers some of the best ways to make GP in OSRS. Whether you’re chasing high-level money makers like Hydra and Vorkath or reliably profitable tasks like Abyssal demons and Skeleton hellhounds, understanding which monsters offer the best value and how to approach them efficiently is key. Keep your gear optimized, practice the best strategies, and focus on maximizing kills per hour — that’s the true path to Slayer profit.
