Writing gems are psionic journals created by mind flayers for recording information. While attuned to one of these 6-inch- diameter gems, you share a mental connection with the item, and while you hold the gem:

• You can record information to the gem.
• You can access any information recorded in the gem.
• You can share all or some of the recorded information in the gem with any willing creature you can see within 10 feet of you. If the gem is attuned to another creature when you touch it, you must succeed on a DC 15 Charisma saving throw. On a failed save you take 6d6 psychic damage and drop the gem. On a successful save, you assert your will over the gem and can attune the item yourself, accessing any recorded information within the item.
