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 you "destroy" the crystal pickaxe you will not be given the dragon pickaxe back; you will have to talk to Lady Ithell to receive a dragon pickaxe. 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%.

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.

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."
