Legendary Some Properties Require Attunement Requires Attunement

Greater lore gems, or selu’kiira in Elvish, are extraordinarily rare and powerful lore gems. They have the same properties of a standard lore gem, except that they vary greatly in size and shape, and they can store several thousand pages’ worth of knowledge, including up to 300 standard magic spells. This makes greater lore gems a favorite among high mages for storing their high magic sourcebooks.

Greater lore gems can be mystically “locked” by an attuned owner so only specific, approved individuals can use them. This lock can only be modified by the attuned user or by means of the wish spell. If an unauthorized creature attempts to wear or access information from a locked greater lore gem, it must make a DC 12 Intelligence saving throw every round until the gem is removed. On a failed save, it takes 1d4 psychic damage.

If the creature is reduced to 0 hit points by this damage, the gem falls to the ground, and the creature must succeed on another DC 12 Intelligence saving throw or become stunned for a number of days equal to 1d10 − its Constitution modifier (minimum 1).
