Crystal tinderbox

The crystal tinderbox is a degradable tinderbox 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 tinderbox, without any harmonic dust or 80 Smithing.

The tinderbox gives quintuple the chance of spawning a fire spirit while training Firemaking with bonfires with it equipped in weapon slot. When it spawns a fire spirit, it loses 3.57% charge, this is lowered to 1.78% in Prifddinas, thus lasting 28 uses or 56 uses respectively. After it loses all charge, it degrades back to the crystal tool seed. 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 tinderbox back into a seed.

Like the other crystal tools, the tinderbox doubles the chance of getting Firemaking strange rocks from Shattered Heart.
