Stonespeaker Crystal

Created by the stone giant librarians of Gravenhollow, this nineteen-inch-long shard of quartz grants you advantage on Investigation (Int) checks. The crystal has 10 charges. While holding it, as an action cast one of the following spells from it: speak with animals (2), speak with dead (4), or speak with plants (3). When you cast a divination spell, you can use the crystal in place of one material component that would normally be consumed by the spell, at a cost of 1 charge per level of the spell.
