Adamant dragon

Adamant dragons are metal dragons found in the adamant dragon dungeon inside Brimhaven Dungeon, accessible via a set of stairs in a room between the moss, fire giants and black demons. The dungeon contains multiple sections; the largest is accessible by anyone, but the smaller rooms are blocked by magical barriers that require 70, 80, or 90 Slayer to pass. The dragons drop pages for Forcae's journal, the journal of the Dragonkin scientist that created them, who was a disciple of Kerapac. They are also the only dragons besides mithril dragons to drop dragon full helms.

The dragons were first announced in the June 2015 BTS. They won the first RuneLabs poll, alongside rune dragons.
