Solo OSRS Bosses for Cash: Best Money Making Strategies in 2025

Hey there, fellow Gielinor adventurers! If you’re grinding Old School RuneScape (OSRS) and looking to stack some serious gold pieces (GP) in 2025, solo bossing is where it’s at. Why solo? No splitting loot, no team drama, just you and the boss. Plus, it’s a flex to take down a big bad all by yourself. I’ve been slaying bosses for years, and I’m here to spill the beans on the best Solo Bosses for cash, their mechanics, gear setups, and strategies to maximize your GP per hour. Ready to get rich? Let’s dive in.

Why Solo Bossing is the Way to Go

Solo bossing in OSRS is a goldmine for players who want full control over their loot and playtime. You don’t need to wait for a raid team or deal with randoms crashing your kills. But which bosses are worth your time in 2025? And how do you make the most GP? I’ve tested these methods myself, and I’m focusing on bosses that are solo-friendly, profitable, Accessible, and fun. Some are easy, some are a pain, but all can fill your bank with gold if you play it smart.

Here’s a quick rundown of what makes a boss worth farming:

High-Value Drops: Think rare items like Zenyte Shards or Dragonbone Necklaces.
Consistent Loot: Regular drops like dragon bones or herbs add up fast.
Low Supply Costs: Less GP spent on food and pots means more profit.
Scalable Difficulty: Pick bosses that match your stats and gear.

Let’s get to the meat of it: the best solo bosses for cash in 2025.

Top Solo Bosses for Money in 2025

Below, I’ve ranked the top solo bosses based on profitability, Accessibility, and how doable they are for mid-to-high level players. I’m assuming you’ve got decent combat stats (base 80+ in Melee, Ranged, or Magic) and some quests done. If you’re lower level, don’t worry, I’ll touch on beginner-friendly options too. Here’s the list:

1. Vorkath: The Money Dragon

Profit: ~2-3M GP/hour
Requirements: Dragon Slayer II, 80+ Ranged, 75+ Defence
Location: Crash Site Cavern (Fremennik Province)
Why It’s Great: Vorkath is the king of consistent Solo profits. His drops, like superior dragon bones and blue dragonhide, are always in demand. Plus, rare drops like the Draconic Visage can make your day.

Vorkath’s been my go-to for years. Why? Because he’s predictable once you learn his patterns. You08:58:26 AM PKT, August 06, 2025 patterns, and you can churn out 25-30 kills per hour with practice. His attacks include standard dragonfire, acid pools, and a freeze attack. Sound tough? It’s not once you get the rhythm.

Strategy

Gear: Elite Void or Armadyl armor, Dragon Hunter Crossbow (or Blowpipe), Anti-Dragon Shield, Ava’s Assembler.
Prayers: Protect from Magic, Rigour (or Eagle Eye).
Tactic: Start with a Bandos Godsword special attack to lower his Defence, then switch to your crossbow. Walk (don’t run) during acid pool phases to avoid damage. Teleport to your POH for quick banking and rejuvenation.
Tip: Use Ruby and Diamond Dragon Bolts (e) for max DPS. If you die, Torfinn charges 100k to reclaim items, so don’t skimp on food!

Pro Tip: Got cash for Dragon Claws? Their special attack is a beast for speeding up kills.

2. Zulrah: The Snakey Cash Cow

Profit: ~2-2.5M GP/hour
Requirements: Regicide (partial), 80+ Magic/Ranged, 70+ Defence
Location: Zul-Andra (south of Port Tyras)
Why It’s Great: Zulrah’s rotations are a puzzle, but once cracked, you’re looking at fast kills and juicy drops like Tanzanite Fang or Serpentine Visage. It’s a solo-only fight, so all loot is yours.

Zulrah’s phases (green, turquoise, crimson) demand prayer switching and movement. Scared? Don’t be. Practice makes it muscle memory. You’ll need a 4-6 way gear switch for efficiency, but even basic Void setups work for starters.

Strategy

Gear: Void Mage/Range, Trident of the Seas, Toxic Blowpipe, Anti-Venom+.
Prayers: Protect from Missiles (green phase), Protect from Magic (turquoise), no prayer for crimson.
Tactic: Learn the four rotation patterns via YouTube guides. Move a few tiles during crimson phase to dodge melee hits. Bank at Zul-Andra or POH for quick resets.
Tip: Start with a 4-way switch (helm, chest, legs, weapon) and upgrade as you get comfy.

3. Demonic Gorillas: Zenyte Farming

Profit: ~4-6.8M GP/hour
Requirements: Monkey Madness II, 70+ Slayer, 80+ Melee/Ranged
Location: Crash Site Cavern
Why It’s Great: These bad boys drop Zenyte Shards (worth millions) and have solid regular loot like rune items. They’re Slayer-only, so you’re training while earning.

Demonic Gorillas are like mini-Zulrahs with prayer-switching mechanics. They use all three combat styles, but Arclight and a crossbow make them manageable. Why are they so profitable? Those rare Zenyte drops can bankroll your next big gear upgrade.

Strategy

Gear: Elite Void or Bandos/Armadyl, Arclight, Dragon Hunter Crossbow.
Prayers: Protect from Melee, Ranged, or Magic based on their attack style.
Tactic: Switch prayers based on their attack animations. Use Arclight for Melee phases and crossbow for Ranged. Bring Divine Combat and Ranging potions for DPS boosts.
Tip: Check out an OSRS Demonic Gorillas guide for their attack patterns.

4. Phantom Muspah: The New Kid

Profit: ~3-5M GP/hour
Requirements: Secrets of the Funereal (partial), 80+ Ranged/Magic, 70+ Prayer
Location: Instanced (Weiss)
Why It’s Great: Phantom Muspah is solo-only, has reactive mechanics, and drops like Ancient Sceptre pieces. It’s less intense than Zulrah but still tests your skills.

This boss is a 2025 meta pick. His attacks are predictable, and the instanced fight means no crashers. Want to know the catch? You need to master prayer flicking and positioning.

Strategy

Gear: Void or Masori, Blowpipe or Shadow of Tumeken.
Prayers: Protect from Ranged/Magic, Rigour.
Tactic: Dodge his spike attacks by moving one tile. Flick prayers based on his attack style. Use high DPS to burn through phases.
Tip: Watch a YouTube guide to nail the timing.

5. Vardorvis: The Desert Dancer

Profit: ~3-5M GP/hour
Requirements: Desert Treasure II, 85+ Melee, 80+ Prayer
Location: Instanced (Varlamore)
Why It’s Great: Vardorvis is mechanically intense but drops Soulreaper Axe pieces. It’s a solo fight, so you keep all the loot. Fun? Heck yeah, if you like a challenge.

This boss is a footwork test with prayer switching and axe-throwing mechanics. Sound tricky? It is, but the rewards make it worth learning.

Strategy

Gear: Bandos, Dragon Hunter Lance, Arclight, or Inquisitor’s Mace.
Prayers: Protect from Melee, Piety.
Tactic: Dodge axe throws by moving diagonally. Use special attacks (Bandos Godsword or Dragon Warhammer) to lower Defence, then go ham with your main weapon.
Tip: Practice makes perfect. Start slow and scale up kills per hour.

Beginner-Friendly Solo Bosses

Got mid-level stats (60-80 combat)? Don’t sweat it. These bosses are easier and still pay out:

1. Sarachnis

Profit: ~1-2M GP/hour
Requirements: 70+ Attack/Strength, no quests
Location: Forthos Dungeon
Why It’s Great: Simple mechanics, decent drops like the Sarachnis Cudgel. Great for Ironmen or mid-level players.

Strategy

Gear: Rune armor, Dragon Scimitar or Abyssal Whip.
Prayers: Protect from Melee.
Tactic: Tank her melee hits and dodge web attacks. Bring a few sharks for safety.
Tip: Use a Skills Necklace to teleport to the Woodcutting Guild for fast banking.

2. Barrows Brothers

Profit: ~1-1.5M GP/hour
Requirements: Priest in Peril, 60+ combat stats
Location: Morytania
Why It’s Great: Six brothers, one chest, and Barrows gear drops. Low risk, high reward for beginners.

Strategy

Gear: Black D’hide, Magic Shortbow, or Rune armor.
Prayers: Protect from Melee (Dharok, Karil, Guthan), Magic (Ahrim).
Tactic: Clear all six brothers, pray correctly, and loot the chest. Use a Mort’ton teleport.
Tip: Prioritize high-value Barrows items like Ahrim’s or Dharok’s gear.

Tips to Maximize Profits

Learn Mechanics: Watch YouTube guides (Alonescape is solid) to master rotations. Practice = faster kills = more GP.
Gear Up Smart: Start with budget setups (Void, Rune armor) and reinvest loot into BIS gear like Dragon Hunter weapons.
Bank Efficiently: Use POH teleports or nearby banks (e.g., Zul-Andra for Zulrah) to cut downtime.
Track Drops: Check Grand Exchange prices daily. Sell high-value items when the market’s hot.
Combine with Slayer: Demonic Gorillas and Cerberus double as Slayer tasks, so you’re training while banking.

Common Mistakes to Avoid

Skimping on Supplies: Don’t run out of food or potions mid-fight. Bring extra Saradomin brews.
Ignoring Mechanics: Prayer flicking and movement are non-negotiable for Zulrah and Vardorvis.
Overgearing in Risky Areas: For Wilderness bosses like Scorpia, stick to 3-4 item setups to avoid PKer losses.
Not Practicing: Expect to die a few times learning rotations. It’s normal. Keep at it.
