OSRS Profitable Slayer Monsters Guide

In Old School RuneScape (OSRS), Slayer is a skill that combines combat training with the thrill of hunting unique monsters for exclusive loot. While many tasks can feel like a grind, certain Slayer monsters stand out for their profitability, offering substantial gold per hour for players willing to gear up and strategize. This guide dives into the most lucrative Slayer monsters in 2025, detailing their requirements, drops, and tips to maximize your earnings. Whether you’re a mid-level player or a seasoned slayer chasing millions, these monsters will help you stack your coin pouch.

Slayer isn’t just about leveling up combat stats; it’s one of the most rewarding skills for making OSRS gold. High-level Slayer monsters drop rare items, noted resources, and unique gear that sell for millions on the Grand Exchange. The key is knowing which tasks to prioritize and how to approach them efficiently. By focusing on profitable monsters, you can turn each task into a payday while progressing toward 99 Slayer.

Balancing Profit and Efficiency

Not all Slayer tasks are created equal. Some monsters offer high experience but poor loot, while others are gold mines despite slower kills. To maximize profit, consider your combat level, gear, and whether you’re on-task for the Slayer helm bonus. Using a cannon or high-tier weapons like the Toxic Blowpipe can boost your kill speed, directly impacting your gold per hour.

Top Profitable Slayer Monsters

Below, we explore the cream of the crop—Slayer monsters that consistently deliver high profits in 2025. These picks are based on current Grand Exchange prices, drop tables, and player-reported earnings. Let’s break them down.

Tormented Demons (Level 85 Slayer)

Why They’re Profitable: Tormented Demons, introduced in 2024, are currently the most lucrative Slayer monsters in OSRS, averaging 8-12M gold per hour on-task. Their drop table includes the coveted Tormented Synapse, which crafts into high-value items, plus consistent rune and dragon gear drops.

• Location: Ancient Guthixian Temple (requires While Guthix Sleeps quest).
• Requirements: 85 Slayer, high combat stats (90+ recommended), and prayer-switching gear.
• Key Drops: Tormented Synapse (20M+), Dragon Claws (5M), Rune Platebody (40k).
• Tips: Use a Toxic Blowpipe or Twisted Bow for DPS, and bring prayer potions to handle their multi-style attacks. A dwarf multicannon can’t be used here, so focus on precise gear switches.

Alchemical Hydra (Level 95 Slayer)

Why They’re Profitable: The Alchemical Hydra remains a top-tier money-maker, yielding 3-5M gold per hour. Its unique drops, like the Hydra Leather and Dragon Thrownaxes, fetch premium prices, and its noted alchemical items add up fast.

Kurasks (Level 70 Slayer)

Strategies to Boost Slayer Profits

Profit isn’t just about picking the right monster—it’s about optimizing your approach. Here are proven strategies to squeeze every gold piece out of your Slayer tasks.

Gear and Inventory Setup

Invest in gear that balances DPS and sustainability. For most monsters, prioritize:

• Slayer Helmet: Boosts damage and accuracy on-task.
• Ava’s Device: Saves ammo for Ranged setups.
• Prayer Gear: Proselyte armor or prayer potions for extended trips.

Your inventory should include high-healing food (sharks or better), prayer potions, and teleports for quick banking. For noted drops, use a looting bag or seed box to reduce banking trips.

Task Management with Slayer Points

Slayer points are your ticket to higher profits. Use them to:

• Extend Profitable Tasks: Monsters like Hydra and Brutal Black Dragons are worth extending for longer sessions.
• Block Low-Profit Tasks: Skip tasks like Dagannoths or Kalphites, which offer poor loot.
• Unlock Upgrades: Get “Bigger and Badder” for superior spawns or “Ring Bling” for Slayer Rings to speed up travel.

Using Cannons and Bursting

For multi-combat areas like the Catacombs, a dwarf multicannon can double your kill speed, especially for Brutal Black Dragons or Kurasks. For magic-based tasks like Dust Devils, bursting with Ancient Magicks can yield 500k-1M per hour while training Magic. Just watch your rune costs to ensure you’re still profiting.

Common Mistakes to Avoid

Even the best Slayer monsters won’t pay off if you fall into these traps. Here’s what to watch out for.

Overusing Expensive Supplies

Drinking overloads or using dragon darts on low-profit tasks eats into your margins. Stick to regular combat potions and adamant darts for most monsters, saving the big-ticket items for bosses like Hydra or Tormented Demons.

Ignoring Safe Spots

Monsters like Kurasks and Brutal Black Dragons can be safe-spotted, reducing damage taken and food costs. Learn the layouts of dungeons like Fremennik or Catacombs to exploit these spots.

Camping Without a Plan

Don’t just grind without banking valuable loot. Use a looting bag or bank every 20-30 minutes to secure your profits, especially for high-value drops like Visages or Claws.

Slayer in OSRS is a goldmine if you play it smart. By targeting monsters like Tormented Demons, Alchemical Hydra, and Brutal Black Dragons, and optimizing with the right gear and strategies, you can earn millions per hour while training one of the game’s most engaging skills. Mid-level players can still cash in with Kurasks and Gargoyles, building up to the big leagues. Start slaying, manage your tasks wisely, and watch your bank grow.
