Top Solo Bosses for Maximum GP in OSRS 2026

Old School Runescape is full of bosses that can make you rich—but not all of them are soloable. Today, we’re breaking down the most profitable solo monsters in OSRS for 2026. These are fights you can take on alone, at any time, and leave with serious RuneScape gold. Whether you’re broke now or just looking for more efficient ways to farm, this guide will point you in the right direction.

1. Chaos Fanatic: Easy GP with High Rewards

Located next to the King Black Dragon’s lair, the Chaos Fanatic is a low-difficulty, high-reward boss. Its most notable drop is the Odium Shard One, worth roughly 2.88 million GP. Using a looting bag and the nearby Chaos Altar allows free prayer regeneration, extending your trips and reducing costs.

Fast travel is simple: teleport to the Lava Maze with a Burning Amulet or use a Gorok teleport tab if you’ve completed Desert Treasure. This boss is primarily a ranged fight in the wilderness, so bring decent gear but avoid risking high-value items. On average, you can make 1.2–2 million GP per hour, with a small chance of acquiring the Chaos Elemental pet.

2. Calvarion: The Undead Challenge

Calvarion is one of three weaker wilderness demi-bosses (alongside Veon and Kalisto). These bosses drop pieces of the Void Waker, one of the most overpowered special attack weapons in the game.

Located northeast of Ferox Enclave in the Graveyard of Shadows, Calvarion is a melee-focused fight. The Salv amulet deals extra damage against this undead foe, making kills more efficient. Once you master its mechanics, you can expect to make over 2.5 million GP per hour, with a max drop of 5.4 million GP from the Void Waker blade.

3. Ario: High Risk, High Reward

Ario is another demi-boss near Ferox Enclave, notable for dropping 10.6 million GP in a Void Waker piece. This boss hits hard through melee, so using ranged or magic combat is strongly advised.

The recommended strategy is to mage Ario with an Occurs Scepter and ice barrage spells, allowing you to freeze the boss and avoid its powerful melee attacks. With proper preparation, you can net 2.6 million GP per hour solo.

4. Spindell: The Spider That Pays

Spindell is considered the most profitable solo wilderness boss, with a max drop of 53.6 million GP. This spider is highly risky due to PKers, so only bring items you’re willing to lose.

Access the boss via Corporeal Beast Cave and run northwest to the web chasm. Melee is recommended, using a crush weapon like a Dragon Mace or Earth Sign Chain Mace, paired with stamina potions to avoid web traps. If you survive, you’ll earn around 5.7 million GP per hour, making it one of the highest-paying solo bosses with moderate difficulty.

5. Mini-Bosses: Barrows, Moons Apparel, and the Gauntlet

Barrows is a classic low-risk money maker, located in Mortania Swamp. Kill all six brothers for a chance at unique drops like Derox Axe (3.8 million GP) and armor pieces worth 1–2 million GP. With 43 Prayer and 50 Magic, you can farm 1–1.5 million GP per hour efficiently.

Moon’s Apparel is unlocked after its namesake quest and offers a trio of melee fights. Protection prayers don’t work here, so maximizing melee defense is key. With stable drops worth millions, this boss can net 2.5 million GP per hour.

The Gauntlet, unlocked through the Song of the Elves quest, is a high-skill, high-reward mini-boss challenge. Regular Gauntlet runs provide 2.1 million GP per hour, while the corrupted version can double that to 4.5 million GP per hour, with potential drops including enhanced crystal weapons worth over 120 million GP.

6. Late-Game Bosses: Grotesque Guardians, Royal Titans, and Zora

Some bosses require quests or Slayer levels but offer excellent returns:

Grotesque Guardians in the Slayer Tower of Mortania drop up to 8.4 million GP and untradeable items for upgraded cannonballs. Requires 75 Slayer.

Royal Titans in Asgarnian Ice Dungeon drop the Twin Flame Staff (8.4 million GP) and provide a fun combat switch challenge.

Zora, the “Money Snake,” is fast-paced and can be killed in 2 minutes per run, netting 2.5–3 million GP per hour. Unique drops like Tanzanite Fang can reach nearly 7 million GP.

7. Endgame Giants: Vorcath, Whisperer, and Vardorus

For players ready for Desert Treasure 2 bosses:

Vorcath (“Money Dragon”) drops consistent GP from bones and hides, averaging 5 million GP per hour. Max unique drops can reach 15 million GP.

The Whisperer is a mage-heavy fight with unique drops like Bellator Rings worth 60 million GP, netting around 9 million GP per hour.

Vardorus in Stranglewood is the hardest and most profitable DT2 boss, dropping Altar Rings worth 190 million GP and potential Soulreaper Axe pieces. Soloing this boss can yield 10 million GP per hour.

Bonus: Solo Raids for Massive GP

Tombs of Amas, with difficulty scaling up to level 500 solos, can generate 15 million cheap Runescape gold per hour. Rare mega drops, like the Tummy Shadow, can instantly turn you into an OSRS billionaire.

Whether you’re at Barrows, risking it at Spindell, or farming DT2 bosses, OSRS 2026 offers high-reward solo content at every level. With proper strategy, gear, and preparation, solo bossing is one of the fastest ways to stack serious GP in the game.
