Marble of the Elemental Anatomist

DESCRIPTION
Taking the form of a small marble with a diameter of about ⅛ in, the Marble of Elemental Destruction is the solidified form of a wizard’s knowledge on Elementals. Any living and sentient creature that swallows the Marble (hereafter the Subject) gains all that knowledge, thus allowing the Subject to utilize Critical Hits, Flanking, and Sneak Attacks against Elementals, though the ally/allies they flank with do not receive the flanking bonus. This is a mind-affecting ability in constant effect upon the Subject and if blocked (I.E. Mind Blank on the subject), the Marble and its corresponding power disappears and reappears at the nearest place a sentient being is either eating or getting ready to eat.

Upon the consumption of the Marble, it dissolves into the Subject’s body. Once the Subject dies (for any reason), the Marble can be found underneath their tongue. If the Marble is not removed from the dead Subject’s mouth within 24 hours or remains unswallowed for 7 full days (168 hours), it begins a sort of “migration”. After this begins, the Marble disappears from its location the next time it is unobserved, appearing at the nearest place a sentient being is either eating or getting ready to eat.

DESTRUCTION
The Marble of the Elemental Anatomist dissolves upon being consumed, and so can only be destroyed in its Marble form. To destroy it, the Marble must be taken to the Elemental Plane of either Air or Water. Once there, it must be fed to one of the native beings, which normally causes the being to explode, dealing 5d20 worth of damage to all creatures within 300 feet. If the native being eats the Marble while within an Antimagic Field, they survive and the explosion is entirely avoided.
