Blue dragon

Blue dragons are powerful monsters. An anti-dragonfire shield or an anti-fire potion is essential when fighting them. They are a very popular monster to slay because the blue dragonhides and dragon bones they drop can be sold for large profits. Blue dragons, along with Green dragons, are one of the most popular dragons to kill.

Strengths and Weaknesses
Blue dragons, like all dragons, have very high defence. Their melee attack can hit up to 10. As with all dragons, an anti-dragon/dragonfire shield or an anti-fire potion is essential when fighting Blue dragons, as it reduces the maximum hit of their breath to about 5. Without one, you could be hit over 50 by their dragonfire.

Ranging from a safe spot is the most popular way to kill them (crossbow is recommend since you can use it in conjunction with an anti-dragon shield). They can also be attacked safely with melee using a Halberd (fire isn't long-ranged).
