OSRS Bosses for Mid Levels: Your Guide to Mid-Tier PvM Challenges

Old School RuneScape (OSRS) offers a thrilling bossing experience for players of all levels, but mid-level players—typically those with combat stats between 60 and 90—often find themselves in a sweet spot. You’ve outgrown beginner bosses like the Giant Mole, yet the high-level titans like Zulrah or the Chambers of Xeric still feel out of reach. This guide dives into the best OSRS bosses for mid-level players, offering manageable challenges, decent loot, and a chance to hone your PvM (Player vs. Monster) skills. Whether you’re after profit, experience, or just some fun, these bosses are perfect for your mid-tier journey.
Mid-level bossing bridges the gap between early-game grinds and endgame content. It’s where you start mastering mechanics, building confidence, and earning rewards that fund your progression. For mid-level players, these bosses provide a balanced mix of accessibility and difficulty, making them ideal for skill development without overwhelming you.
Skill Development for Future Challenges
Facing mid-tier bosses teaches you essential combat techniques like prayer flicking, gear switching, and positioning—skills that pay off when you tackle tougher foes later. It’s a low-stakes way to practice without the steep gear or stat requirements of endgame PvM.
Rewards to Boost Your Account
The loot from these bosses often includes mid-tier gear upgrades, cash stacks, and unique items. These rewards can bankroll training methods or help you gear up for harder content, keeping your progression on track.
Top OSRS Bosses for Mid-Level Players
Here’s a curated list of bosses tailored for mid-level players. Each offers a unique challenge and reward, accessible with moderate stats and gear. Let’s break them down.
Barrows Brothers
The Barrows Brothers are a classic mid-level bossing experience in OSRS. Located in Morytania, this group of six undead siblings offers a mix of combat and puzzle-solving.
- Combat Level: 70-90 recommended
- Location: Barrows, east of Mort’ton
- Gear: Magic (Trident of the Seas or Iban’s Blast), melee (Whip or Dragon Scimitar), and basic armor (Black D’hide or Rune)
- Rewards: Barrows armor (Dharok’s, Guthan’s, etc.), runes, and coins
The mechanics are straightforward: defeat each brother in their crypt, navigate the tunnels, and face a final brother. Prayer management is key, but the fight is forgiving for mid-level stats. A single run can net you 500k-1M GP if you luck into a Barrows piece.
Crazy Archaeologist
This Wilderness boss is a chaotic yet rewarding option for mid-level players willing to brave PvP territory.
- Combat Level: 60-80 recommended
- Location: Ruins south of Lava Maze (Level 24 Wilderness)
- Gear: Ranged (Magic Shortbow or Blowpipe), cheap risk gear
- Rewards: Rune Crossbow, Onyx Bolts, and Ancient Shards
The Crazy Archaeologist uses ranged and magic attacks, including an AoE special you’ll need to dodge. Stay mobile, and watch for PKers. It’s a quick fight with solid loot potential, averaging 100k-300k per kill.
Sarachnis
A giant spider boss designed with mid-level players in mind, Sarachnis is a step up from basic mobs but manageable with decent gear.
- Combat Level: 70-85 recommended
- Location: Forthos Dungeon, Hosidius
- Gear: Melee (Abyssal Whip or Dragon Scimitar), Protect from Melee
- Rewards: Sarachnis Cudgel, Giant Egg Sac, and hard clue scrolls
Sarachnis summons spiderlings and switches attack styles, but the mechanics are simple: tank the hits, kill the adds, and keep your prayer up. It’s a great intro to multi-phase fights, with drops averaging 50k-200k per kill.
Gear and Preparation Tips for Mid-Level Bossing
Success against these bosses doesn’t require BiS (Best-in-Slot) gear, but smart preparation can make a big difference. Here’s how to set yourself up.
Recommended Stats and Gear
Aim for these baseline stats: 70+ Attack, Strength, Defence, and 60+ Prayer. Ranged and Magic should be 70+ if you’re using those styles. Gear-wise, stick to affordable options:
- Melee: Rune armor, Dragon Scimitar, or Abyssal Whip
- Ranged: Black D’hide, Magic Shortbow, or Toxic Blowpipe
- Magic: Mystic robes, Trident of the Seas, or Iban’s Staff
Bring a Rune or Dragon Defender for melee, and don’t forget a decent shield like a Book of Law or Dragonfire Shield if you’ve got one.
Inventory Setup
Your inventory should balance combat efficiency and survival:
- Food: Sharks or Monkfish (10-15)
- Potions: Super Combat Potion, Prayer Potion (2-4)
- Teleports: One-click escape (e.g., Teleport Tab or Jewelry)
- Extras: Antipoison for Sarachnis, spade for Barrows
Adjust based on the boss—Wilderness trips need less risk, while Barrows runs benefit from extra prayer pots.
Strategies to Defeat Mid-Level Bosses
Each boss has quirks you can exploit with the right approach. Here are tailored strategies to maximize your success rate.
Barrows Brothers Strategy
Use Magic to shred through most brothers, saving melee for Dharok (he hits hard if low HP). In the tunnels, loot the chest fast and tele out if you’re not chasing high kill counts. Prioritize Protect from Melee for safety.
Crazy Archaeologist Strategy
Stick to Ranged, and sidestep the “Rain of Knowledge” special attack (watch for the exclamation mark). Bring minimal risk gear—3-4 items max—and bank loot frequently to avoid PKer losses. A Bulwark can help if you’re paranoid about dying.
Sarachnis Strategy
Melee is your friend here. Use Protect from Melee, kill spiderlings quickly with AoE (like a Dragon Dagger spec), and watch your HP during her sticky web attack. Solo runs are fine, but duoing speeds things up.
Loot and Profit Potential
Mid-level bosses won’t make you a billionaire overnight, but they offer steady income and useful items. Here’s a breakdown of what you can expect.
Profit Table for Mid-Level Bosses
Boss | Average GP per Kill | Notable Drops | Time per Kill |
---|---|---|---|
Barrows Brothers | 500k-1M (with rare drops) | Barrows armor, runes | 10-15 mins/run |
Crazy Archaeologist | 100k-300k | Rune Crossbow, Onyx Bolts | 2-4 mins |
Sarachnis | 50k-200k | Sarachnis Cudgel, Giant Egg Sac | 3-5 mins |
Note: Profit varies based on RNG and GE prices. Barrows shines with rare drops, while the others provide consistent smaller payouts.
Long-Term Value
Beyond raw GP, these bosses drop items that enhance your account. Barrows gear like Guthan’s is great for Slayer, the Rune Crossbow boosts your Ranged setup, and Sarachnis’ cudgel is a solid mid-tier weapon. Plus, clue scrolls from Sarachnis can lead to bigger windfalls.
