Dragon pickaxe

A Dragon pickaxe is the most powerful pickaxe in the game. After being the subject of many rumours over the years, Mod Mark confirmed that it was in development on 5 March 2009 Quote on the Q&A update. They were released with the Forgiveness of a Chaos Dwarf quest on 9 September 2009. To wield a Dragon pickaxe, players must have an Attack level of at least 60. To mine using a dragon pickaxe, level 61 Mining is required. The Dragon pickaxe is dropped by killing Chaos dwogres or any kind of chaos dwarf (in the cave)

Special Attack
The special attack is called "Shock" and drains 5% from an opponent's Attack, Ranged and Magic. This attack takes longer to perform than a normal attack.

Trivia

 * There was no record of the Dragon pickaxe in the Knowledge Base on the day of release.
 * On the release day for the Dragon pickaxes, all other metal pickaxes underwent an unannounced graphical update.(This was a spoiler to show that a new pickaxe had come out.)
 * Before the update there was an image in the Runescape banner of a dual-headed dragon pickaxe. The same one is currently used to show the special attack in the Knowledge Base, despite the look of the real dragon pickaxe.
 * The information on the Knowledge Base page concerning the Chaos Dwarf Battlefield is vague about who exactly drops the pickaxe. If read correctly, the page states that any NPC of Chaos Dwarf alignment, even regular Chaos Dwarfs, can drop the pickaxe.
 * It is super cool!
