Crystal weapon seed

A Crystal weapon seed is what is left over after a crystal weapon's charges are used up.

Prior to the release of Prifddinas, this item was known as a crystal seed. With the city's opening, crystal seeds were renamed and reclassified into three distinct types:
 * Crystal weapon seed
 * Crystal teleport seed
 * Crystal tool seed

Obtaining a Seed
Uncharged crystal weapon seeds can be obtained by:
 * Drops from Cadarn mages and rangers, and Iorwerth guards and scouts.
 * Using up all of the charges of a piece of crystal equipment.
 * Having a crystal singer revert a piece of crystal equipment.

Creating Equipment
Prior to the completion of Plague's End, uncharged crystal weapon seeds can be converted into a bow or shield by Ilfeen for a price. The price falls each time IIfeen converts a seed to shield/bow. The minimum prices that Ilfeen will charge are 180,000 coins for bows and 150,000 coins for shields. Alternatively, bows and shields can be purchased new from Islwyn without needing a crystal seed.

One of the rewards for completion of the Roving Elves quest is a partially charged (2/10) crystal bow or crystal shield.

On completion of Plague's End, by which players gain access to Prifddinas, players also gain access to Eluned's crystal-singing service in the Tower of Voices. Here, she will sing uncharged crystal weapon seeds into a greater variety of equipment for a fee:

Magic equipment: Staff, wand, orb and ward.

Melee equipment: Halberd, dagger, off-hand dagger and shield.

Ranged equipment: Bow, chakram, off-hand chakram and deflector.

Eluned's weapon singing fee works in a similar way to Ilfeen's, with fees ranging from 1,000,000 coins down to 200,000, decreasing every time the player uses the service.

Trivia

 * When a crystal weapon loses its charge, the seed is left in the relative combat slot.
