List of Bosses in OSRS: Your Ultimate Guide to Old School RuneScape Bosses


Old School RuneScape (OSRS) is packed with thrilling boss encounters that test your skills, strategy, and patience. Whether you’re a beginner looking to dip your toes into PvM (Player vs Monster) or a seasoned adventurer chasing rare loot, this comprehensive list of bosses in OSRS will guide you through Gielinor‘s toughest challenges. From solo skilling bosses to group raids, we’ve got you covered with details on every major boss, their locations, and what makes them unique. Let’s dive into the world of OSRS bossing and explore the monsters that await!

If you’re new to bossing in OSRS, starting with easier encounters is the way to go. These bosses offer straightforward mechanics, decent rewards, and a chance to build your confidence before tackling the harder foes.

Giant Mole

Found beneath Falador Park, the Giant Mole is one of the simplest bosses in OSRS. With a combat level of 230, it’s an excellent starting point for players with mid-level stats (around 60 Melee and 43 Prayer). Use Protect from Melee to mitigate its attacks, and bring a light source to navigate its lair. The Mole drops Mole Claws and Skins, which can be traded for a decent profit, plus a rare chance at the Baby Mole pet.

King Black Dragon (KBD)

The King Black Dragon, a level 276 beast, resides in a lair accessible via the Wilderness. Despite its location, it’s beginner-friendly with the right gear—equip an Anti-Dragon Shield and Anti-Fire Potions to counter its dragonfire. Soloing is possible, but teaming up makes it easier. Rewards include the Dragon Pickaxe and a shot at the Prince Black Dragon pet, making KBD a staple for early PvMers.

Chaos Fanatic

This Wilderness boss, located near the Lava Maze (level 42 Wilderness), is a level 202 magic user. Its green orb attacks deal AoE damage, but Protect from Missiles and decent magic defense gear (like Black d’hide) keep you safe. The Chaos Fanatic drops Odium and Malediction Shards, valuable for crafting wards, and offers a low-risk introduction to Wilderness bossing.

Slayer and Skilling Bosses

OSRS blends combat with skilling through unique bosses tied to Slayer tasks or non-combat skills. These encounters offer variety and often great rewards for dedicated players.

Kraken

A Slayer-only boss requiring 87 Slayer, the Kraken lurks in Kraken Cove. At level 291, it’s a laid-back fight—disturb the whirlpools to summon its tentacles, then attack the main body with magic (Protect from Magic recommended). The Trident of the Seas and Kraken Tentacle are standout drops, making it a profitable choice for Slayer enthusiasts.

Cerberus

Located in Taverley Dungeon, Cerberus is a level 318 hellhound requiring 91 Slayer. Its ghost summons demand quick prayer switches (Protect from Melee, Magic, or Ranged), but with high combat stats (80+), it’s manageable. Drops like the Primordial, Eternal, and Pegasian Crystals upgrade best-in-slot boots, making Cerberus a must-farm boss.

Wintertodt

The only skilling boss in OSRS, Wintertodt is a firemaking challenge in Great Kourend. No combat level is required—just 50 Firemaking. Players light braziers and chop roots to subdue it, earning Firemaking XP and loot like the Tome of Fire and a rare Dragon Axe chance. It’s perfect for skillers and Ironmen alike.

Wilderness Bosses

The Wilderness is home to some of OSRS’s riskiest yet rewarding bosses. PKers (player killers) add an extra layer of danger, but the loot can make it worth the gamble.

Venenatis

A level 464 giant spider near the Graveyard of Shadows (level 20-30 Wilderness), Venenatis uses melee and magic attacks, including a web that traps players. Safe spots and Protect from Magic help, but watch for PKers. Drops include the Dragon Pickaxe and Venenatis Spiderling pet, appealing to high-risk adventurers.

Callisto

This level 470 bear roams near the Demonic Ruins (level 40 Wilderness). Its powerful melee hits can be mitigated with Protect from Melee, and a team of 2-4 is ideal for beginners. Callisto drops the Tyrannical Ring and has a chance at the Callisto Cub pet, making it a popular Wilderness target.

Corporeal Beast

A level 785 titan in a cave near the Graveyard of Shadows, the Corporeal Beast is a Wilderness heavyweight. It’s best tackled in teams due to its high HP (2000) and damage resistance—spears or stabs work best. Rare drops like the Elysian Sigil (worth hundreds of millions) and the Spectral Spirit Shield make it a goldmine for brave groups.

Group Raids and High-Level Bosses

For advanced players, OSRS offers complex group content and solo challenges that demand top-tier gear, coordination, and mastery of mechanics.

Chambers of Xeric (Raids 1)

Located under Mount Quidamortem, the Chambers of Xeric is OSRS’s first raid. This non-linear dungeon pits teams against multiple bosses, culminating in the Great Olm (level 1043). Mechanics like acid pools and crystal attacks require teamwork and strategy. Rewards include the Twisted Bow, Dragon Claws, and Ancestral Robes—some of the game’s most valuable items.

Theatre of Blood (Raids 2)

In Meiyerditch, the Theatre of Blood is a linear raid with six unique bosses, ending with Verzik Vitur (level 1040). Each fight—like the Maiden of Sugadinti’s blood pools or Xarpus’s poison—tests different skills. Soloing is possible but brutal; groups shine here. Drops like the Scythe of Vitur and Justiciar Armour are best-in-slot treasures.

TzTok-Jad and the Inferno

TzTok-Jad (level 702) awaits in the TzHaar Fight Cave after 62 waves of enemies. Its one-hit-kill attacks demand perfect prayer switches—listen for audio cues. Beyond Jad lies the Inferno, a 69-wave gauntlet ending with TzKal-Zuk (level 1400). Completing it earns the Inferno Cape, the ultimate PvM badge of honor.

Quest and Unique Bosses

Many OSRS bosses are tied to quests or offer one-of-a-kind experiences, blending story with combat challenges.

Vorkath

Unlocked after Dragon Slayer II, Vorkath (level 732) resides on Ungael. This blue dragon’s acid pools, firebombs, and zombie spawn phase require precise movement and a Dragon Hunter weapon. Solo-only, it’s a profit machine with drops like the Dragonbone Necklace and Vorkath’s Head for the Ava’s Assembler upgrade.

Zulrah

In Zul’Gwenwynau, Zulrah (level 725) is a solo boss with rotating phases (melee, magic, ranged). Memorizing its patterns is key—bring a Toxic Blowpipe and Trident of the Seas. Drops like the Tanzanite Fang and Magic Fang (for best-in-slot weapons) make it a favorite for consistent gold.

The Nightmare

In Slepe, the Nightmare (level 814) is a group or solo boss with shifting phases—totems, sleepwalkers, and AoE attacks keep you on your toes. High combat stats (90+) and supplies like Saradomin Brews are essential. Rewards include the Inquisitor’s Set and Nightmare Staff, top-tier gear for crush and magic.
