The adamant battleaxe is a tier above the mithril battleaxe and a tier below the rune battleaxe. Like all adamant weapons, players must have at least level 40 Attack to wield it.
Players may obtain by purchasing it at Brian's Battleaxe Bazaar specialty store in Port Sarim, or the Grand Exchange. At level 80 Smithing, a player may smith one using 3 Adamant bars, giving the player 187.5 Smithing experience.
- Like all other adamant weapons, the Adamant battleaxe used to require 30 Attack to wield; this was changed to 40 Attack with the Evolution of Combat.
