Spellshard
Category: Gear
Price: 100 gp
Weight: .5 lb
Description: Spellshards are fragments of crystal that contain power and knowledge, usually of an arcane nature. If your class would normally store its arcane powers in a spellbook, you can instead store your powers in a spellshard if you possess one.
All the enchantments and features available through a tome are also available through a spellshard. Members of any class can use a spellshard in place of a ritual book or a ritual scroll.
