Mithril dragons can be found and fought in the Ancient Cavern. To access the Ancient Cavern, the player needs to start the pyre ship section of the Barbarian Training miniquest. Be wary as these monsters are extremely powerful. Their release broke the King Black Dragon's long-standing record as being the strongest dragon. They are the only monster from which the dragon full helm can be obtained, either as a very rare drop, or as a rare reward for offering chewed bones on a pyre ship.

It is strongly recommended to use antifire potions in conjunction with an anti-dragon shield (or a dragonfire shield) when fighting these along with the appropriate protection prayer. Alternatively, a super antifire potion can be used in conjunction with a defender for higher damage per second.

Killing a mithril dragon is a requirement for the hard Kandarin Diary. The mithril dragon fought during Dragon Slayer II does not count towards the hard Kandarin Diary.

To access the Ancient Cavern, one must have completed the first part of Barbarian Firemaking training and then talked to Otto about pyre ships. After the conversation is over, the player can now go in the whirlpool. Upon entering, one must climb down stairs and then run south to a set of stairs leading up to the mithril dragons. Note that dwarf multicannons are not allowed in the Ancient Cavern.

Mithril dragons can use all three attack styles as well as dragonfire. The dragon will pick a physical attack 60% of the time (melee if the player is in melee distance, ranged if not), and a magic attack 40% of the time. If the chosen style was ranged or magic, a 20% chance is then rolled for the attack to be replaced with a dragonfire attack.^[1] Mithril dragons' ranged attacks are magical ranged, rolling against the player's magic defence but negated by Protect from Missiles. The Justiciar armour set effect will reduce the incoming damage according to the player's ranged defence bonus.

• Prior to the release of Dragon Slayer II, mithril dragons were brighter in colour. Their old appearance was given to rune dragons to make them appear more like the metal's true colours.
