Crystal pickaxe

The Crystal pickaxe is the fastest pickaxe available. It is obtained by trading a dragon pickaxe and 4,000 Harmonic dust to Lady Ithell, in the Ithell Clan district of Prifddinas. If the player has an Imcando pickaxe or a Gilded dragon pickaxe, Lady Ithell will degrade them to a dragon pickaxe before upgrading to the Crystal pickaxe. 70 Attack is required to wield it, and 71 Mining to mine with it. While the Imcando pickaxe has a higher level requirement, it only has a better mining speed when used in the Lava Flow Mine. Everywhere else, the crystal pickaxe is roughly 15% faster.

The crystal pickaxe can be added to the toolbelt. It features an improved mining speed compared to a dragon pickaxe and players using it have twice the chance to gain strange and golden rocks. Players may convert their crystal pickaxe back to a dragon pickaxe by speaking to Lady Ithell, however they will not be given back the harmonic dust previously used to upgrade the tool. If a gilded dragon pickaxe was used to create a crystal pickaxe, it will remain gilded if it is downgraded again.

Just like the dragon pickaxe, the crystal pickaxe has a special attack, Shock, which requires 100% adrenaline and drains your opponent's Attack, Ranged, and Magic by 5%.

Trivia

 * Even though the mining requirement is level 71, the pickaxe can only be obtained in Prifddinas after finishing Plague's End which has a non-boostable requirement of 75 mining.
 * When trying to gild the crystal pickaxe, the nymph will say "That pickaxe is coated with crystal. I'm so sorry. I don't understand elven magic well enough to add gold to crystal."
 * Given a rate of 600 dust per hour at the harps, obtaining the crystal pickaxe is worth it if you would spend 51 hours or more mining normally.
 * When mining the Rockslide on Kethsi, the golden trim on the pickaxe is displayed as a cyan colour. It is unknown if this is a bug.
