Blue dragon - OSRS Wiki

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 up to 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.
