A baleful groan, as of a strong wind blowing through the hollows of the earth, endlessly emanates from this uncut, fist-sized diamond.
Three times per day, the bearer of the Moaning Diamond can reshape earth and stone as if by the spell stone shape, affecting 5,000 cubic feet of material. Once per day the Moaning Diamond can also summon an elder earth elemental with maximum hit points that serves the caster until it is slain; only one such elemental can be summoned at a time. The sound of the Moaning Diamond is almost impossible to disguise, granting creatures a +10 bonus on Perception checks to detect the diamond's presence or that of its bearer.
The Moaning Diamond must be smashed by the combined power of the elemental lords, and the dust must be cast into a place where it will never fall upon stone, or the Moaning Diamond will eventually reconstitute itself.
