Best Places To Kill Dagannoths in Old School Runescape

Dagannoths are fast, aggressive creatures in Old School RuneScape that are commonly assigned as Slayer tasks and known for their great XP rates and solid drops. Whether you’re farming for bones, clue scrolls, or just grinding Slayer, finding the right spot to kill Dagannoths can make your trip much more efficient. In this guide, we’ll break down the best places to kill Dagannoths in OSRS, from safe, low-level options to high-risk, high-reward areas, so you can choose the spot that fits your goals and combat level best.

#1: Jormungand’s Prison

First up on the list is Jormungand’s Prison, located on the Island of Stone—an ideal spot for players who want to breeze through their Dagannoth Slayer tasks with a cannon. Every Dagannoth in this area is the level 92 melee-only variant, making it perfect for safe cannoning. Simply set up your Dwarf Multicannon in the center of a room, activate Protect from Melee, and you can sit back as your cannon shreds through them without needing to worry about incoming damage. It’s one of the most efficient setups available, especially for high Slayer XP rates. Just be cautious not to wander into nearby rooms full of Basilisk Knights—they’re far tougher and not what you’re here for. To access Jormungand’s Prison, you’ll need to complete the master-level quest The Fremennik Exiles, but the payoff is absolutely worth it.

#2: Catacombs of Kourend

The Lighthouse, found at the southwestern edge of the Fremennik Province, is a great beginner-friendly spot for killing Dagannoths. Think of it as a more accessible, lower-risk version of Jormungand’s Prison. The Dagannoths here are some of the weakest in the game, making this location perfect for low-level players or those just getting started with Slayer. It’s also cannon-friendly, so if you want to speed things up, you can set up a Dwarf Multicannon to boost your kill rate. Whether you’re training combat or knocking out early Slayer tasks, the Lighthouse offers a simple and efficient place to farm Dagannoths without needing high stats or quest requirements.

#3: The Lighthouse

The Lighthouse, found at the southwestern edge of the Fremennik Province, is a great beginner-friendly spot for killing Dagannoths. Think of it as a more accessible, lower-risk version of Jormungand’s Prison. The Dagannoths here are some of the weakest in the game, making this location perfect for low-level players or those just getting started with Slayer. It’s also cannon-friendly, so if you want to speed things up, you can set up a Dwarf Multicannon to boost your kill rate. Whether you’re training combat or knocking out early Slayer tasks, the Lighthouse offers a simple and efficient place to farm Dagannoths without needing high stats or quest requirements.

#4: Waterbirth Island

Waterbirth Island is home to the most dangerous Dagannoths in the game—the legendary Dagannoth Kings. These three bosses—Rex, Prime, and Supreme—each specialize in a different combat style (melee, magic, and ranged), and they’re found deep within the Waterbirth Dungeon. Reaching them requires navigating through multiple levels filled with aggressive creatures, so come well-prepared. The Dagannoth Kings are not to be taken lightly—even though they’re considered mid-level bosses, they hit hard, and poor preparation can lead to a quick death (Prime alone can hit over 30 damage in a single cast). However, the rewards are well worth the risk. Their rare drops include the highly sought-after Berserker, Archers, and Seers Rings, the Dragon Axe, and three unique boss pets—one for each king. This spot is ideal for experienced players looking for high-level combat and profitable loot. Pro tip: if you’re going in solo, don’t forget a Pet Rock and Rune Thrownaxes—they’re essential for accessing the boss room.

Conclusion

Dagannoths are a versatile and rewarding monster to kill in Old School RuneScape, whether you’re a new player looking for an easy Slayer task or a seasoned veteran hunting high-value drops. From the cannon-friendly efficiency of Jormungand’s Prison to the burstable clusters in the Catacombs of Kourend, each spot offers something unique depending on your combat style and goals. Beginners will find the Lighthouse a perfect starting point, while high-level players can take on the Dagannoth Kings at Waterbirth Island for some of the best rings and loot in the game. No matter your level, there’s a Dagannoth spot that fits your grind perfectly.
