Obtained by playing a Harmonium Harp in the Ithell Sector of Prifddinas
; Pickpocketed from Ithell workers.
Used to make Crystal equipment.
The higher your Crafting
level, the faster you'll obtain both experience and Harmonic dust while playing a harp, however, they'll slowly go out of tune as you play and the rate will decrease until the harp must be re-tuned after obtaining 100 dust.
At 75 Smithing
you can take this dust and either a Crystal tool seed
, Crystal armour seed
, or Crystal weapon seed
to the Singing bowl north of Lady Ithell and make your own Crystal equipment.
A Crystal pickaxe
or Crystal hatchet
can be made by taking 4,000 Harmonic dust and the respective dragon tool to Lady Ithell to have her encase them in crystal for you.
Used in conjunction with a crystal seed to crystal sing.
