Crystal chisel

The crystal chisel is a degradable chisel that is made by Crystal Singing with a crystal tool seed and 150 harmonic dust. This requires 80 Smithing and gives 300 Smithing experience. Alternatively, you can pay Ilfeen, Eluned, Islwyn or Rhodri Dail 1,500 - 7,500 coins to turn a crystal tool seed into a crystal chisel, without any harmonic dust or 80 Smithing.

The chisel gives a 2% chance of giving you an extra gem of the type you were cutting, but it only applies to sapphire, emerald, ruby, diamond and dragonstone. The chisel will consume 3.57% charge or 1.78% while in Prifddinas per gem created, so it will create 28 or 56 gems before reverting back to a crystal tool seed. If there is no room in your inventory for the extra gem, it will be sent to your bank. The tool seed can be recharged by Ilfeen, Eluned, Islwyn or Rhodri Dail for a cost that starts at 7,500 coins but decreases by 1,500 every enchant, to a minimum of 1,500 coins.

You can also talk to Ilfeen, Eluned, Islwyn or Rhodri Dail if you want to turn your chisel back into a seed.

Like the other crystal tools, the chisel doubles the chance of getting Crafting golden rocks and strange rocks from Shattered Heart.
