Crystal seed

Prior to the release of Prifddinas, a crystal seed used to be what was left over after a crystal weapon's charges were used up.

With the city's opening, crystal seeds were renamed and reclassified into six distinct types:
 * Crystal weapon seed
 * Crystal teleport seed
 * Crystal tool seed
 * Crystal armour seed
 * Attuned crystal armour seed
 * Attuned crystal weapon seed

Crystal seeds were obtainable by buying from players, buying new crystal equipment at a minimum price of 750k (crystal shield) and 900k (crystal bow) and then using them until they decayed into a seed or by getting them from a Crystal geode obtained while chopping down a Crystal tree.

As of 29 September 2014, players can now re-attune old crystal seeds to obtain a crystal weapon seed.

Trivia

 * When a crystal weapon lost its charge, the seed was left in the relative combat slot.
 * Nowadays it's still possible to obtain a Crystal seed by looting a Crystal impling. It is not known if this is a bug or not.
