Wondrous Item

Very Rare Divination Requires Attunement

A turquoise stone, fitting in a human's hand palm, these gems were dubbed "Mimic Stones" by Oswald Fleetfeet after he retrieved one of these from the Grand Archives of Gildin. Their name owes origin both to the beast he and his companions fought to retrieve the object, a Mimic, and the stones ability to mimic the essence of a spell for transcribing by the item's wielder

Upon attunement by the stone's wielder, the stone can memorize one spell cast by another spell caster within 60 feet of the stone if the spell caster is visible to the stone's wielder. This ability only triggers if the spell cast & stored is no more than one spell level higher than the wielder's maximum available spell slot level, and the stone currently doesn't hold a memorized spell inscription. Spells stored this way must be available to the caster upon level up, or a successful spellcasting check must be made against DC 10 + 2 * the spell's level. The stone's wielder must spend 2 times the stored spell's level to transcribe the spell into a spell scroll or wizard booklet, in order to effectively learn the spell. After transcription, or upon speaking "Govey" (Dovah for "remove"), the spell is no longer stored in the stone and another spell can be memorized by the stone.
