Old School RuneScape is full of ways to make money, from traditional skilling methods to intense high-end PvM. But when it comes to making serious GP per hour in 2025, bossing continues to dominate. Many players assume that bossing is only for elite players with maxed stats, hundreds of hours of experience, and billions in gear. But the reality is, a large portion of RuneScape's bosses are accessible to mid-level players and can generate millions of OSRS gold per hour with relatively low difficulty.

In this guide, we'll cover 15 bosses that are perfect for players looking to step into PvM, each with low-to-mid mechanical complexity, modest gear and stat requirements, and incredible money-making potential. Whether you're new to bossing or just looking to expand your rotation, these bosses can help you stack GP while building skill and confidence.

1. Barrows (750K+ GP/H)

Difficulty: 1/10

Requirements: 2/10

Barrows remains one of the easiest PvM encounters and got even easier thanks to the magic rebalance. Now weak to air spells, all six Barrows Brothers can be melted with basic wind spells once you reach 60 Magic. Gear cost is minimal-5 to 10 million GP at most-and no gear switching is required. It's a low-stress intro to bossing, ideal for newer accounts or players easing into combat.

2. Dagannoth Rex (1M+ GP/H)

Difficulty: 2/10

Requirements: 2/10

Dagannoth Rex is the easiest of the DK trio, especially when safe spotted. With low magic defense, you can reliably hit using Iban Blast and tanky armor like Torag's. The main challenge is navigating the Waterbirth Dungeon and isolating Rex. Once mastered, Rex is an AFK-friendly boss with a high chance of scoring the Berserker Ring, which still fetches a premium.

3. Colosseum Wave 1 Farming (1.5M-2.5M GP/H)

Difficulty: 2/10

Requirements: 3/10

Farming just the first wave of the Colosseum is one of the most efficient and underrated money-making methods right now. With 75+ melee stats and budget gear (5-30M), you can earn guaranteed Splinters quickly and safely. It's not the most engaging method, but the profits add up fast. Bring a Dinh's Bulwark and grind out those 80 Splinters per run in under a minute.

4. Royal Titans (2M GP/H)

Difficulty: 3/10

Requirements: 3/10

The Royal Titans are a great introduction to gear switching and offer very forgiving mechanics. A variety of gear setups can work-from dragon scimitars to scythes-and while 75+ in all combat stats is ideal, the boss is manageable with just 15M-50M in gear. With potential drops like the Twinflame Staff (worth 5M), this is one of the best mid-game bossing experiences for money and skill building.

5. Perilous Moons (Up to 3M GP/H)

Difficulty: 3/10

Requirements: 3/10

A modern reimagining of Barrows, Perilous Moons offer higher rewards for similar effort. Movement is more important than gear switching, and mechanics are simple. With Blood Moon and Blue Moon drops selling for millions, this is an ideal mid-game money maker. Tanky Barrows gear works well here, and kills are fast once you learn the movement patterns.

6. Giant Mole (1M GP/H)

Difficulty: 1/10

Requirements: 4/10

The Giant Mole is extremely easy to kill, especially using the Dharok's Rock Cake method to maximize damage. However, the Falador Hard Diary is required for mole tracking, making the skill threshold a bit higher. Still, it's a fantastic low-effort option that only requires about 10M in gear.

7. Calvar'ion (1.5M+ GP/H)

Difficulty: 4/10 (due to Wilderness)

Requirements: 3/10

Calvar'ion is a wilderness boss with low mechanical complexity but some risk. Gear costs are intentionally kept low to minimize loss risk, and weapons like the Osmumten's Chainmace are best-in-slot despite only costing 7M. With unique drops like the Voidwaker Blade and Ring of the Gods, it's a consistent profit engine for players on a budget.

8. Commander Zilyana (2M-4M GP/H)

Difficulty: 2/10

Requirements: 5/10

Zilyana is one of the easier God Wars Dungeon bosses, with a simple attack-and-run mechanic. Requirements are higher (70 Agility, 85 Ranged recommended), and gear can be expensive, but it's highly rewarding-especially with Bow of Faerdhinen, which can net you 4M+ per hour. A dragon crossbow works too, though at slower kill speeds.

9. Zalcano (2.5M GP/H + Mining XP)

Difficulty: 2/10

Requirements: 4/10

Zalcano is technically a skilling boss, but after recent changes, it's become a highly profitable and fast-paced activity. You now choose between XP or loot mode, and opting for XP still gives you access to Crystal Shards and rare drops like the Crystal Tool Seed. You'll need Song of the Elves and 70 Mining, but once in, you can make bank while passively training a skill.

10. Demonic Gorillas (4-5M GP/H)

Difficulty: 5/10

Requirements: 6/10

Demonic Gorillas are mechanically more intense, requiring frequent gear switches and solid positioning. You'll need Monkey Madness II and ideally 80+ inRanged and Melee, but the reward is worth it. With Zenyte Shards hitting massive prices in 2025, gorillas can yield 5M per hour if you're efficient. Best-in-slot setups cost ~150M, but even Arc Light setups can work well.

11. Vorkath (4-5M GP/H)

Difficulty: 3/10

Requirements: 6/10

Vorkath is incredibly profitable thanks to the skyrocketing price of Superior Dragon Bones. With Dragon Slayer II completed and 80+ Melee or Ranged, you can get consistent kills using setups around 100M GP. The Salve Amulet is key to maximizing DPS. Once you learn the Wooks walk and projectile dodges, you can grind profit with minimal supply cost.

12. Zulrah (2-4M GP/H)

Difficulty: 5/10

Requirements: 4/10

Zulrah remains a high-reward boss with relatively low entry requirements: Regicide, 75 Ranged and Magic, and modest gear. Learning the patterns is the biggest hurdle, but once you're confident, it's possible to pull 30-40 kills an hour. Even a Trident and Blowpipe setup can yield 2M+ per hour. It's a classic for a reason.

13. Sarachnis (1-1.5M GP/H)

Difficulty: 3/10

Requirements: 3/10

Sarachnis is a great early-game boss located in the Forthos Dungeon. It has simple mechanics and drops like the Giant Egg Sac that fetch good prices. Mid-level melee stats (70+) and cheap gear like Verac's or a whip setup can take you far here. It's not as flashy as other bosses, but the low entry barrier makes it a consistent option.

14. Kraken (1.5M-2M GP/H)

Difficulty: 1/10

Requirements: 3/10

Kraken is a Slayer-only boss that's essentially AFK. With a Slayer level of 87 and a trident, you can sit back, relax, and rake in cash from trident parts and the Kraken Tentacle. It's not exciting, but it's one of the most brain-dead profitable tasks in the game.

15. Tempoross (1M+ GP/H + Fishing XP)

Difficulty: 1/10

Requirements: 2/10

Much like Zalcano, Tempoross is a skilling boss-this time tied to Fishing. It offers solid GP alongside fishing XP, and it's nearly risk-free. With minimal requirements and decent loot like the Tome of Water or Spirit Flakes, it's a great way to earn while training. You'll need 35 Fishing to enter, but beyond that, it's extremely chill.

Final Thoughts

Bossing in Old School RuneScape doesn't have to be reserved for the elite. In 2025, the landscape is full of accessible bosses that reward players with millions of OSRS GP for reasonable effort. Whether you're looking for something easy like Barrows or Giant Mole, or something a bit more hands-on like Demonic Gorillas or Vorkath, there's a money-making method here for every mid-level PvMer.

By stepping out of the skilling grind and into these encounters, not only will you increase your GP/hr drastically, but you'll build valuable combat experience for RuneScape's hardest (and richest) endgame bosses down the road. Time to get out there and claim your loot!
