Spirit Shards

Spirit shards are used in the Summoning skill along with charms to create Pouches to summon Familiars. Spirit shards can be purchased from Pikkupstix in Taverley (at the starting point of the Wolf Whistle quest), for 25 coins, and at the other Summoning Shops.

Spirit shards may be traded between players, but are strangely not available on the Grand Exchange.

Criticism
The price of spirit shards have stirred a lot of criticism with members. When Summoning was first released the price was 50 coins each. With a lot of pouches players needed high amounts of shards to make them. With the price so high, many players started giving up on Summoning. After reading the forums, Jagex decided to half the price, although many players still find this price expensive.
