Blue dragon

Blue Dragons are the second weakest chromatic dragons, but are still fairly powerful monsters. An anti-dragonfire shield is essential when meleeing them, but may be skipped if ranging or maging them. They are a very popular monster to slay because the blue dragonhides and dragon bones they drop can be sold for 0 coins.

If given blue dragons as a slayer task a player may kill baby blue dragons instead. When fighting these with melee an abyssal whip is also a good choice for a weapon for a player with 85+ strength, especially with a super strength and super attack potion.

Locations

 * Taverley Dungeon (3) - Is usually crowded; has lots of stalagmites for safe spots for rangers and mages
 * Ogre Enclave (6) - Best place for Slayer tasks or for money, multiple safe spots but is generally crowded
 * Heroes' Guild (1) - Usually has one or more persons already there, safe spot available to range or mage, because it is caged. It is possible to enter to get your loot.
 * Kuradal's Dungeon (5) - Blue dragons can only be killed when assigned as a task from Kuradal.

Taverley Dungeon
The area is an ideal spot for rangers and mages, but due to its popularity, is often crowded. Players of low to medium combat levels may face more potential dangers than those of higher levels. Level 97+ players should consider this a very good spot in an unpopulated world, however, it is a very popular spot, so it may take time to find such a world.

Ogre Enclave
The blue dragons here are only available for players who have completed "Watchtower" quest. This place has many safespots for ranging or maging and with six dragons here it is easy to get one for yourself. This spot is not too far from Yanille or Castle wars bank. A commonly used method is to use the Ring of duelling to get to Castle wars bank once the player has filled up his inventory, then he will run back to ogre enclave to repeat the process.

Heroes' Guild
A blue dragon is present in a cage in the cave below the Heroes' Guild. This is generally not an ideal place for training on them. Although, because the dragon is in a cage, if you are ranging, it is unnecessary to have an anti-dragonfire shield. This spot though may be ideal for some as it has 2 safe spots for ranging and if using a Games Necklace allows for quick banking by Teleporting to the Wilderness Volcanoe and back to Burthorpe. Banking this way takes only about 1 minute.

Kuradal's Dungeon
The dragons here may only be attacked if you were assigned blue dragons as your slayer task by Kuradal. There are safe spots for rangers and mages.

Strengths and weaknesses
Blue dragons, like all dragons, have very high defence. Their melee attack can hit up to 102. As with all dragons, an anti-dragon shield or dragonfire shield is essential when fighting blue dragons, as it reduces the maximum hit of their breath from 500 to about 50 (0 if used with or an anti-fire potion.) If a player wishes to kill them with a two handed weapon, a simple anti-fire potion greatly decreases the accuracy and average damage of their dragon-fire attack. For melee, it is best to use stabbing weapons when killing these dragons such as a leaf blade sword or to a lesser extent, dragon longsword. However, for higher levelled players, an Abyssal whip or other high levelled weapon will work just as well.

Ranging from a safe spot is the most popular way to kill them (mithril crossbow or higher is recommended, since you can use it in conjunction with an anti-dragon shield). They can also be attacked safely with melee using a halberd since a regular chromatic dragon's fire is not long ranged.

Strangely these dragons are extremely weak to magic despite being made out of dragonhide. However green, red, and black dragons still have relatively high magic defence as intended. it is currently unknown why these dragons differ.
