Blue dragon

Blue dragons are the third strongest of the chromatic dragons, behind red dragons and black dragons. Like all dragons, they can breathe dragonfire, which can inflict over 50 damage if proper protections aren't used. Dragonfire can be mitigated by equipping an anti-dragon shield or a dragonfire shield – alongside the usage of an antifire potion, which will completely negate dragonfire damage. On top of the strong dragonfire breath, they also attack with an accurate slash attack.

Protections from Dragonfire
The following methods will provide partial protection: The following methods will provide 100% protection, but each has its own pros and cons:
 * An anti-dragon shield or a dragonfire shield (permanent): offers high protection, reducing dragonfire damage significantly
 * An antifire potion (temporary): offers partial protection, resulting in damage reduction generally with resistance similar to the shield mentioned above. Occasionally, you may be 'horribly burnt by the dragon fire', receiving moderate damage
 * An antifire potion + an anti-dragon or a dragonfire shield: temporary but saves a large amount of food considering how long each potion lasts
 * An antifire potion + Protect from Magic: not advised due to the high cost of prayer potions, this is only recommended for players with a high level Prayer

Alternate methods to avoid usage of potions includes the Heroes' Guild, which has a blue dragon in a fenced off area that can be safe spotted. If one has partially completed Watchtower there are safespots in the Ogre Enclave with 6 dragons that spawn. There are also a few safespots on the most western wall of the blue dragon room in the Stronghold Slayer Cave. Taverley Dungeon also has some safespots with the use of the columns and big eggs.
