If you've been grinding away at skilling in Old School RuneScape hoping to make serious GP, it's time to face the music: combat is king when it comes to money-making OSRS gold. While many top-tier bosses like Theatre of Blood or the Inferno have intimidating mechanics and steep requirements, the truth is that plenty of other bosses can be farmed for massive profits with just a little practice.

In this guide, we're covering 15 bosses you can kill for up to 5-7 million GP per hour, all without needing perfect mechanics or maxed stats. We'll rank them by mechanical difficulty and gear/stats requirements, helping you gradually step up your bossing game and rake in some serious cash.

1. Barrows (Difficulty: 1/10 | Requirements: 2/10)

Barrows has never been easier, especially with the magic rebalance that made the Brothers weak to air spells. All you need is 60 Magic and a wind spell, making it the ultimate entry-level boss. No gear switching needed, and a basic Ahrim's set (or cheaper alternatives) will carry you just fine. While it only pulls in around 750k GP/hour, it's an excellent first step into PvM.

2. Dagannoth Rex (Difficulty: 2/10 | Requirements: 2/10)

Soloing Rex is shockingly easy once you learn how to isolate him. Just bring 50+ Magic, Iban Blast, prayer pots, and some food. The challenge lies in navigating Waterbirth Dungeon safely and positioning Rex into a safespot. But once you're in place, it's smooth sailing - and the Berserker Ring makes this a 1-1.5M GP/hour boss.

3. Colosseum Wave 1 Farming (Difficulty: 2/10 | Requirements: 3/10)

This might sound odd, but repeatedly clearing Wave 1 of the Colosseum is one of the best low-requirement money makers right now. You'll get 80 splinters per wave, and each clear takes under a minute once you master the strategy. With 75+ melee stats and a Dinh's bulwark, you can earn up to 2.5M GP/hour. It's boring, yes - but brutally effective.

4. Royal Titans (Difficulty: 3/10 | Requirements: 3/10)

The Royal Titans are a fantastic mid-game boss for learning gear switching. You'll need 75+ in all combat stats (melee, range, and some magic), but gear-wise you can start with a rune crossbow + dragon scimitar combo and work your way up to higher DPS setups. Expect around 2M GP/hour, especially if you snag the Twinflame Staff, currently valued at 5M+.

5. Perilous Moons (Difficulty: 3/10 | Requirements: 3/10)

Think of this as Barrows 2.0 - but with higher stakes. These moon-themed bosses reward minimal gear switching and rely mostly on positioning and movement. With a chance to pull 12M GP items (like the Blood Moon armor), you can earn up to 3M GP/hour. Gear requirements are flexible, and anything tanky will work due to their ramping damage mechanics.

6. Giant Mole (Difficulty: 1/10 | Requirements: 4/10)

The boss fight is hilariously easy - just bring Dharok's, rock cake yourself to 1 HP, and bonk the mole. But the catch is you need to complete the Falador Hard Diary, which includes 72 Slayer, 70 Prayer, and 60 Mining. The GP/hour isn't spectacular at ~1M/hour, but it's nearly zero effort once set up.

7. Calvar'ion (Difficulty: 4/10 | Requirements: 4/10)

Don't let the wilderness setting scare you off - Calvar'ion is a great boss for budget builds, especially since the Best-in-Slot weapon (Accursed Sceptre) only costs around 7M. With Dragon mace and Salve amulet, you can earn over 1.5-2M/hour consistently. Just keep an eye out for PKers and minimize your risk by wearing cheap gear.

8. Commander Zilyana (Difficulty: 2/10 | Requirements: 5/10)

70 Agility and 85+ Ranged is needed here, and the better your gear, the more profitable the kills. With a Bow of Faerdhinen, you can hit 4M/hour, but even a Dragon crossbow setup can earn you 1.5-2M/hour. The fight itself is simple - run around the room attacking Zilyana while avoiding her deadly melee hits.

9. Zalcano (Difficulty: 2/10 | Requirements: 6/10)

This skilling boss is an outlier, but a good one. With Song of the Elves and 70 Mining, Zalcano's rework now lets you choose between XP or loot. Even if you pick XP, you'll still receive Crystal shards and a shot at the Crystal Tool Seed, making 2.5M/hour possible while training Mining. Bring a Dragon pickaxe and you're good to go.

10. Demonic Gorillas (Difficulty: 5/10 | Requirements: 6/10)

After Monkey Madness II, these creatures become your gateway to the lucrative Zenyte shard drops, worth around 15M each. They do require gear switching (range + melee), and you'll want 80+ combat stats. But with the right setup, especially on a Slayer task, you're looking at 4-5M/hour. Bonus: the gear cost can be kept low with Arclight.11. Vorkath (Difficulty: 4/10 | Requirements: 5/10)

Vorkath is one of the most consistent and well-loved bosses for a reason. Post Dragon Slayer II, with 85+ Ranged and decent gear (like Dragon Hunter Crossbow), you can easily earn 2-4M/hour. His mechanics areconsistent, and once learned, the fight becomes automatic. A top-tier boss for people who want steady money without wild mechanics.

12. Zulrah (Difficulty: 5/10 | Requirements: 5/10)

Zulrah remains one of the best solo bosses in the game. With a firm grasp of his rotations and gear switching, you can make up to 3-4M/hour. You'll want 85+ Magic/Ranged, good gear, and some practice. Once you get consistent, Zulrah becomes a goldmine with drops like Tanzanite fang and Onyx.

13. Kraken (Difficulty: 1/10 | Requirements: 5/10)

This AFK-friendly boss is a staple for casual Slayer profit. Requiring 87 Slayer, the fight is brain-dead simple: use Magic and dodge nothing. Trident of the Seas or Swamp is all you need. Expect around 1M/hour, maybe more if you get a Kraken tentacle or Trident drops. Set it and forget it.

14. Thermonuclear Smoke Devil (Difficulty: 2/10 | Requirements: 6/10)

93 Slayer unlocks this one, and it's another great AFK boss. The Smoke Battlestaff is a valuable unique, and the consistent rune and herb drops make it reliable for 1-1.5M/hour. Use Magic and tank gear to just face tank the fight while watching Netflix.

15. Nightmare of Ashihama (Difficulty: 6/10 | Requirements: 7/10)

For those ready for a real challenge but not quite on the level of raids, Nightmare is a rewarding mid-to-endgame boss. Drops like Inquisitor's mace and Nightmare staff still fetch high prices. With coordinated teams and solid mechanics, 4-6M/hour is doable, but expect some practice and deaths on the way.
