Blue dragon

Blue dragons are the second weakest of the chromatic dragons, but are still fairly powerful magic-class monsters. They primarily attack with magic, by shooting a Fire Bolt spell at the player, as well as both close-range and long-distance dragonbreath. Thus, an anti-dragon shield, a Dragonfire shield, a Super antifire potion, or the Protect from Magic or prayer are essential when fighting them, as they can hit well over 1000 with their breath otherwise (Resonance does not work against their breath). They also use melee if the player is standing next to them. They are a very popular monster to kill because the blue dragonhide and dragon bones that they drop may be sold for 0 coins, together. They do not drop the draconic visage. Blue dragons are popular targets for bot farming, which accounts for much of the player crowding in their locations.

Locations

 * Taverley Dungeon (3) - commonly crowded on busier worlds.
 * Taverley resource dungeon (8) - dungeon requires level 60 Dungeoneering to enter. Released with the new Dungeoneering Resource Dungeons on the 19 July 2010 Dungeoneering update.
 * Ogre Enclave (6) - often crowded, even if on a less busy world.
 * Heroes' Guild (1) - often there will be one or more other players there.
 * Kuradal's Dungeon (5) - blue dragons can only be killed here when assigned as a slayer task from Kuradal.

Taverley Dungeon
There are three adult blue dragons here. As this place isn't too crowded, players should consider this a very good spot in an unpopulated world. You will need a dusty key in order to reach the blue dragons within the dungeon, unless you have an Agility level of at least 70 (or 65 with summer pies), in which case a shortcut by the entrance leads straight to where the dragons are. Fighting these while collecting the blue dragon scales can earn up to 400k coins per hour. This will only happen if you have or can boost to 70 Agility.

The best way to get to the dungeon entrance is to use the Taverley lodestone and going south through Taverley. There is a bank nearby in Taverley just north of the dungeon entrance.

Taverley Dungeon resource dungeon
The blue dragons here are only available for players who have a Dungeoneering level of 60 and above. There are a total of eight blue dragons in this Resource Dungeon. There are two ways to get to the resource dungeon. The first is to go through Taverley Dungeon ensuring that you have a dusty key and enter the blue dragons' enclosure with the dusty key, then within the enclosure you will see the resource dungeon containing the blue dragons. The second, quicker route, is using the Agility shortcut (requiring a level of 70 to use, or 65 with a summer pie). There are also twelve respawn spots of blue dragon scale in the resource dungeon. Though this is an excellent place, it is often crowded with bots.

Ogre Enclave
There are six dragons inside the ogre enclave under Gu'tanoth, south of Yanille. The quickest way to get to the enclave is to use a Watchtower Teleport (especially if the destination is set to inside Yanille) or a house or Yanille tablet. Alternatively players can use a ring of duelling to teleport to Castle Wars, or the fairy rings to reach any of the rings in the area.

The blue dragons here are only available for players who have completed or partially completed the Watchtower quest. This spot is not too far from the Yanille or Castle Wars bank.

Heroes' Guild
This location has a single dragon, in a cage in the guild basement. Completion of the Heroes' Quest is required to access this dragon. The guild can be reached by using a lodestone teleport to Burthorpe and running south, or by using the combat bracelet to reach the Warriors' Guild and running east then south.

This dragon is contained inside a cage, making it ideal for mages or rangers to fight, although the cage must be entered to pick up the drops, and the dragon can still use its magic and dragonbreath through the bars.

Kuradal's Dungeon
The blue dragons here may only be attacked if you are assigned blue dragons as your slayer task by Kuradal. Players may bank relatively quickly using a bank teleport (such as the TokKul-Zo) and then returning to the dungeon using a Ferocious ring, a drop unique to the monsters in the dungeon. Alternatively, players may use the fairy ring in the ancient cavern and bank in Zanaris, providing that the player has repaired it. If players do not want to bank by Zanaris, teleporting to Lunar Isle (after completion of Lunar Diplomacy) or Edgeville will provide the fastest ways of banking.

Strengths and weaknesses
Being mages, blue dragons are weak to ranged attacks, most notably arrows. Since bows require two hands to wield and do not provide dragonbreath protection, super antifires or the Protect from Magic prayer are required if this method is to be used. Because of the resources required for exploiting the dragons' exact weakness, most players will generally prefer to use one-handed crossbows or thrown weapons in tandem with Anti-dragon shields or Dragonfire shields when engaging them. While not as effective as bows, they still provide a consistent kill rate if the player is using a strong enough weapon and ammunition, and has a sufficiently high Ranged level. If the player has 85 Herblore or is willing to pay for the required prayer potions, however, it is strongly advised to use a bow as this will ensure the fastest kills if abilities are timed properly, especially when using stronger bows such as the Crystal bow and Zaryte bow.

If magic is your preference, you should use the highest levelled wand you can wield, in tandem with an anti-dragon shield or a Dragonfire shield (magic). Use the most damaging spell you can cast, and time your abilities carefully. If you have access to super antifires, you can opt to instead use an Armadyl battlestaff in tandem with Storm of Armadyl, or a polypore staff.

Due to their classification as mages, it is not recommended to engage these monsters in melee combat. If melee is still preferred, the best option is to bring a dragonfire shield or anti-dragon shield, high-tier armour, and a high-levelled one-handed weapon such as the Chaotic rapier or abyssal whip. Attack and Strength levels of at least 75, a super set or better, and careful use of both offensive and defensive abilities as well as prayer are essential to attaining a consistent kill rate with melee due to being at a disadvantage on the combat triangle.
