Mithril dragon

The Mithril dragon is found in the Ancient Caverns which may be accessed by completing the Barbarian Training. Since they are metal, they are weak to magic attacks.

Its release shattered the King Black Dragon's long standing record as being the strongest dragon in RuneScape.

Its Melee attacks can hit 28s, and its Mage and Ranged attacks can hit 18s, and they are not firebreath attacks. Mithril dragons are also immune to poison. Many high-leveled players have stated that they can only kill four or five in one trip unless they are using a Unicorn stallion.

Players have found that by wearing Full Karil with a rune crossbow and using Enchanted ruby bolts and enchanted diamond bolts, Mithril Dragons can be killed fairly easily and quickly.
 * The enchanted ruby bolts have a chance to reduce your health by 10%, and your opponents by 20%. Because Mithril Dragons have such high hitpoints, this can hit up to 50 damage.
 * After half health, the damage dealt is no longer as high. So switching to enchanted diamond bolts is effective because they have a chance to negate a large amount of your opponent's Ranged defence, making them much easier to hit.
 * They use their ranged attacks most frequently, so protect from missiles prayer works well.
 * Some players have stated that prayer-switching in the same manner as when defeating Tz-Tok-Jad works here; however, you must range the mithril dragon from a very great distance, and it usually means that other mithril dragons nearby can attack you immediately as soon as you kill the current one.

The Mithril Dragon holds one record. It is currently:
 * The highest level dragon.
