The Jeweled Queen's Soulbound Oval Ruby

Appearing at first like an expensive, masochistic adornment, this almond-sized star ruby is set in a gold clasp, one side of which is festooned with several long spikes. A soulbound oval ruby is not an item that most creatures would voluntarily wear—they are instead crafted by powerful creatures who wish to use another creature as a sort of remote-viewing slave. A soulbound oval ruby must be attached to a willing or helpless creature by pressing the spike-covered surface to the creature’s body—the gem swiftly and painfully embeds itself in the victim’s flesh, immediately activating to forge a shared link between the wearer and the creature who placed the item on its head (the “master”).   Once implanted, the soulbound oval ruby allows the master to observe the world around the wearer through the wearer’s senses. It also allows for telepathic communication between the wearer and the master.   The soulbound oval ruby’s wearer is not compelled to obey its master’s telepathic commands, but the master can use the soulbound oval ruby as a conduit for hold monster, modify memory, pain strike, or suggestion spells, treating the wearer as the target of the spell, no matter the distance between master and wearer. The victim is allowed any normal saving throws or spell resistance against spells cast through the soulbound oval ruby.   The soulbound oval ruby grants its wearer immunity to poison and all disease, including supernatural diseases- as if wearing a periapt of proof against poison, and a periapat of health. It also sustains the wearer without food, water, or air. It also grants its wearer acid resistance as if wearing a major ring of energy resistance.   While implanted the soulbound oval ruby protects you from ability score penalties from aging and you cannot be magically aged. Any penalties you have already incurred remain in place. Bonuses still accrue, and you still die of old age when your time is up. If you lose the stone or its abilities are negated in some way, all age and penalties apply immediately.   An implanted soulbound oval ruby functions like a cursed item once it is in place—it can only be removed if the curse is first lifted via an effect like remove curse or break enchantment. Once removed, a soulbound oval ruby crumbles to fragments.
