Blue dragons are the third-strongest dragons in OSRS. They can be killed consistently with medium combat stats and are quite profitable. They can be assigned as a Slayer task at level 65 combat or higher after starting Dragon Slayer I. As a slayer task, it is worth it to kill Blue Dragons if you have low to medium combat stats. However, high-level players should focus on other tasks that give better slayer XP as killing blue dragons is generally slow.

Variants of the Blue Dragon

These variants can be killed when assigned to a Blue Dragon slayer task.

Regular Blue Dragons (level 111)

Blue dragons are weak to all attack styles but weaker to stab melee attack. They use a slash melee attack with a max hit of 10 and breathe fire at the player.

Baby Blue Dragons (level 48)

These are the easiest to kill. They are weak to all attack styles and use a melee slash attack style with a max hit of 5. The Tarverley is the best location to kill these dragons as it contains the most spawns.

Brutal Blue Dragons (level 271)

This variant is found in the northwest section of the Catacombs of Kourend and the Ruins of Tapoyauik. They use melee, magic and their dragon fire attack has a longer range. Turn on Protect from Magic and use an antifire potion to protect character from damage completely. 

Vorkath (level 732)

Vorkath is also considered a blue dragon. It is much more difficult to kill, but it’s quite profitable. Follow our Vorkath guide to find the best strategy for killing it consistently.

Blue Dragons attacks

Blue dragons attack with melee and dragonfire. The Dragonfire attack can inflict up to 50 damage without any protection. Equipping an anti-dragon shield or a dragonfire shield along with an antifire potion will nullify the damage from the attacks. 

Strategy for Killing Blue Dragons

Killing Blue Dragons is quite straightforward. Their hits can be tanked with good gear and the anti-dragon fire shield, especially for players with high defence stats. If you have low combat stats, you might have to use protection prayers. Using a slash weapon is recommended to attack them as it’s weakest to those attacks, and they are cheaper than ranged or magic. 

Safespots for Blue Dragons

• Fenced area in the Heroes’ Guild: A blue dragon is in a fenced-off area in the Heroes’ Guild which can be easily safespotted. 

• Ogre Enclave: six dragons spawn in the Ogre Enclave which can be safespotted.

• Taverley Dungeon: players can safespot Blue Dragons using columns and big egg.

GP per hour from Blue Dragons

With the recommended stats above, experienced can kill Blue Dragons 100 times per hour. This results in 550K GP per hour after the costs of teleports and potions have been deducted.
