|Release date||3 July 2007 (Update)|
|Always drops||Dragon bones and 3 Mithril bars|
|Experimenting with mithril gone bad!|
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 Firemaking in Barbarian Training. Be wary as these monsters are extremely powerful. Their release broke the King Black Dragon's long-standing record as being the strongest dragon in RuneScape. 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.
The ability to be assigned mithril dragons can be purchased for 80 Slayer reward points. Once unlocked, they can be disabled, but players must spend another 80 points to unlock them again.
Slayer Masters offer to convince Mithril dragons to drop their bars in noted form while on a slayer assignment, for a cost of 200 slayer points.
If they are fought without complete dragonfire protection, it is recommended to stay in melee range and use Protect from Melee, to reduce the amount of dragonfire damage taken.
Mithril dragons can be found on the top level of the Ancient Cavern. Note that dwarf multicannons are not allowed in the Ancient Cavern.
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.

- 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 metals' true colours.
