5 Profitable Midgame Bosses to Master PvM in Old School RuneScape

Many Old School RuneScape players get stuck in the midgame plateau. You have 70+ combat stats, a few million GP in the bank, and you’re tired of green dragons or repetitive Slayer tasks. High-end money makers look locked behind elite requirements, and while some players look into shortcuts like buy OSRS gold, that doesn’t mean you can’t generate strong, consistent profit through actual gameplay right now. This guide breaks down five midgame bosses that build real PvM fundamentals while steadily growing your bank-no max gear or tick-perfect execution required.

What “Midgame” Really Means

For this guide, midgame assumes:

· 70+ Attack, Strength, Defence, Ranged, and Magic

· 43 Prayer minimum (Protection prayers unlocked)

· 70 Prayer ideal (Piety or equivalent offensive prayers)

Higher stats increase forgiveness, but you do not need 90+ across the board.

Budget gear works:

· Melee: Fighter torso, obsidian legs, abyssal whip

· Ranged: Black d’hide, rune crossbow

· Magic: Mystic robes, Iban’s staff or trident

Core upgrades like Ava’s device, fire cape, god cloak, and Barrows gloves meaningfully increase efficiency.

Expect to die while learning. Early supply losses are tuition fees. The bosses below are forgiving enough that even imperfect runs remain profitable while teaching transferable PvM skills: prayer management, movement, gear switching, and inventory discipline.

1. Sarachnis – Foundational PvM Training

Sarachnis is arguably the most approachable true boss encounter in the game.

Requirements: None.
Access: Forthos Dungeon (Hosidius teleport recommended).
Profit: ~900k–1.2M GP/hr.

Sarachnis emphasizes:

· Prayer switching

· Recognizing attack animations

· Handling adds

· Maintaining DPS uptime

Drops consist largely of noted resources and alchables, with occasional elite clues and the cudgel unique. While the uniques aren’t premium-tier anymore, the fight’s consistency and mechanical clarity make it ideal for developing PvM muscle memory.

If you want low stress and steady returns, this is your entry point.

2. Perilous Moons – Combat Style Adaptation

The Moons of Peril require completing Perilous Moons, which also functions as a tutorial.

Recommended stats:

· 75 Attack (Zamorakian hasta access)

· 75 Defence (Barrows armor comfort)

Profit: ~2M GP/hr (unique-dependent)

The Zamorakian hasta is the key. It supports stab, slash, and crush, letting you adapt to each Moon’s weakness without bringing multiple weapons.

Each boss in sequence tests adaptation:

· Eclipse Moon: Heavy melee damage; pray melee and respect special attacks.

· Blue Moon: Magic-based freeze mechanics; maintain spacing and pray mage.

· Blood Moon: Stat drain and minion spawns; prioritize add control.

This encounter trains combat-style switching and rapid strategic adjustment-core competencies for raids and advanced PvM. With low supply drain and meaningful unique potential, it’s both educational and lucrative.

3. Royal Titans – Multi-Target Mechanics

The Royal Titans (Ice King and Fire Queen) introduce dual-boss pressure.

Requirements: None.
Recommended stats: 75+ melee or ranged; solid Magic.
Location: Asgarnian Ice Dungeon.
Profit: ~1.5–2M GP/hr.

Core mechanics:

· Ranged when distant, melee when close (DPS optimization)

· Elemental counterplay (fire spells delete ice minions; ice spells delete fire minions)

· Enrage phase safe-spot positioning

When both bosses are low HP, they enter a charge phase. Missing the designated safe tile results in heavy damage. This reinforces spatial awareness under pressure.

Duo play is highly encouraged-each player receives independent loot, meaning zero downside to teaming.

This fight develops:

· Multi-target prioritization

· Positioning discipline

· Elemental awareness

· Enrage-phase composure

It’s one of the most mechanically engaging midgame encounters available without quest gates.

4. The Gauntlet – Mechanical Mastery

Unlocked after completing Song of the Elves, the The Gauntlet is a zero-investment PvM simulator.

You bring nothing in. All gear, potions, and food are crafted inside under a time constraint.

Normal Gauntlet:

· 75+ combat stats recommended

· 50–100k per completion

Corrupted Gauntlet:

· ~4–5M GP/hr

· Chance at enhanced crystal seed (high-value drop)

Core mechanics include:

· Tile-based environmental damage

· Prayer-disabling attacks

· Style-switching requirements

· Tornado movement checks

Normal Gauntlet acts as structured training. Corrupted Gauntlet becomes elite-tier income once mastered. This content teaches comprehensive PvM competency: resource management, time allocation, prayer precision, and mechanical consistency.

If you want to future-proof your PvM skillset, this is mandatory progression.

5. Barrows – Reliable, Low-Stress Profit

Barrows remains a staple for a reason.

Access: Priest in Peril
Highly recommended: Morytania Hard Diary (25% rune boost)
Profit: ~1M GP/hr average

Since elemental weakness updates, all brothers are weak to air spells. A basic air staff plus death runes (Wind Blast) clears efficiently.

Each brother requires correct overhead prayer. The Hallowed Sepulchre’s strange lockpick accelerates tunnel runs significantly.

Barrows delivers:

· Frequent unique rolls (≈1/hr average)

· Minimal gear investment

· Low cognitive load

It’s ideal for relaxed sessions or mobile play while maintaining consistent returns.

Final Perspective

Your first 5–10 kills at any boss in Old School RuneScape will feel inefficient. That is normal. The skill delta between your 5th and 50th kill is enormous. Cleaner mechanics reduce supply cost and increase GP/hr organically, making your progress far more sustainable than relying on shortcuts like cheap OSRS gold.Midgame PvM isn’t about perfection-it’s about progression. Master these encounters, and higher-tier content becomes significantly more accessible.
