Aura faint transmutation; CL 7th
Slot none; Price 5,200 gp; Weight 15 lb.
This multi-faceted gemstone is as large as a human skull, and noticeably heavy for its size. It glows from within with a faint amber light that pulsates rhythmically (similar to a heartbeat), gently vibrating as each pulse reaches its apex of intensity.
Once per day an earthbound gem allows its user to use a number of different spell-like abilities: soften earth and stone (CL 3rd) once per day, stone shape (CL 5th) once per week, and transmute rock to mud (CL 7th) once per month. Each time the earthbound gem is used there is a cumulative 1% chance that the user is turned to stone as flesh to stone (CL 11th). This cumulative chance only dissipates if the earthbound gem is unused for a full. An earthbound gem is activated when the user holds the large jewel in one hand and uses their other hand to touch the target of its spell-like abilities.
Success on a Knowledge (history) check to learn more about an earthbound gem reveals some facts about the unique item’s lore:
DC 15 Legends surrounding the creation of the Stone Sentinels of NaeraCull mention that even after the titanic creatures were petrified, their hearts still beat, the life-force within sustaining their existence in a motionless state where they are forced to helplessly gaze out over the land they so loved. [More informationcan be found in Grimstark Stoneturner’s Research!]
DC 20 Some researchers claim that earthbound gems are used to animate the inanimate. The existence of this magic item within the core of one of the Stone Sentinels brings to question whether they are simply statues or instead immobile living constructs.
DC 25 While not exceedingly powerful, earthbound gems are exceptionally rare because they are notoriously difficult to craft. Earthbound gems are highly sought after by artificers as a core component in the construction of many powerful stone-based constructs and golems.
Before starting to craft an earthbound gem, the ruby components must be stored together in a stone mold and heated to a red-hot glow once per day for six months (to create the single massive gem); otherwise the gem cracks during the crafting attempt.
