Ioun Stones




Aura strong varied; CL 12th; Slot —; Price varies; Weight

DESCRIPTION

These crystalline stones always float in the air and must be within 3 feet of their owner to be of any use. When a character first acquires a stone, she must hold it and then release it, whereupon it takes up a circling orbit 1d3 feet from her head. Thereafter, a stone must be grasped or netted to separate it from its owner. The owner may voluntarily seize and stow a stone (to keep it safe while she is sleeping, for example), but she loses the benefits of the stone during that time.

Ioun stones have AC 24, 10 hit points, and hardness 5. The powers of each stone vary depending on its color and shape.

Note: Each stone is linked to more details for that particular type of stone and additional details regarding inferior and implanted ioun stones appears below the following table.

Facts About Ioun Stones

Ioun stones only float when sent spinning around the head of an intelligent (Int 3+) creature; otherwise they are as inert as common stone. They have no effect on animals, mindless constructs, and other non-sentient creatures; comatose intelligent creatures and those with significant Intelligence damage or drain cannot use ioun stones. An ioun stone has no particular affinity for the living—intelligent undead and the rare intelligent construct can make full use of them.

Despite their ability to float, ioun stones cannot support more than their own weight. They cannot be used to anchor ropes or support creatures. An ioun stone must be able to orbit freely around a creature’s head (or placed in a specialized matrix like a wayfinder) for its power to be active. Creatures without heads usually cannot use ioun stones. The orbit of an ioun stone reflects the thoughts and emotions of its owner; particularly intense emotions have been known to reverse a stone’s orbit or even momentarily stop it in its path.

Ioun stones in orbit never collide with other stones or creatures by chance, and automatically change course to avoid any obstacles in their path. This in large part explains the difficulty of striking an ioun stone in battle. An ioun stone in orbit counts as an attended object, and benefits from any magical protections possessed by its owner.

Classification by Shape

The shape of an ioun stone can help classify it and thus its powers; the first step is recognizing what each of the shapes means. Cabochon and spherical stones are usually smooth and the others are usually faceted.

  • Cabochon: A convex top with a flat bottom. Most are elliptical or tear-shaped.
  • Disk: A flat circle, typically convex on both sides but sometimes in a lens-like shape.
  • Ellipsoid: An elongated sphere, sometimes tapering at one end to a tear-like shape.
  • Nodule: Asymmetrical but generally rounded.
  • Pentacle: A type of disk, but with five sides rather than being round. The sides are usually straight rather than curved.
  • Prism: A long stone where the top and bottom ends have the same number of sides (such as a hexagram). The width and angle of each side is usually the same as all other sides.
  • Pyramid: A cone-like shape with a point at one end, a flat base, and long facets connecting the two. Typical pyramids have three or four-sided bases, but some have a dozen or more.
  • Rhomboid: A type of prism with sides of unequal widths or angles, giving it a flattened cross section.
  • Sphere: Essentially round in all dimensions.
  • Spindle: A kind of prism with 10 or more sides, giving it a nearly round cross section.
  • Trillian: A type of disk, but with three sides (either straight or curved outward) rather than being round.

Advanced Ioun Stones

Most ioun stones use the normal pricing rules for magic items; the major difference is that they all use the ×2 modifier for not using a magic item space on the body. For example, figuring out the price of upgrading a deep red sphere ioun stone from a +2 enhancement bonus to a +4 enhancement bonus is just a matter of using the formula (bonus squared × 1,000 gp × 2), which gives a final price of 32,000 gp; the difference between that and the standard item cost of 8,000 gp is 24,000 gp, so a qualified character with the Craft Wondrous Item feat can upgrade the stone by spending half that amount (12,000 gp) in materials.

Implanted Ioun Stones

Not all the secrets of the ioun stones lie with the Ancients. While the First Humans mastered the intrinsic powers of the stones, uncovering new attributes and binding them to devices, the Second Empire explored the interaction of ioun stones and the mind and body, and in time devised a means of implanting an ioun stone within the flesh. This process, originally believed to be irreversible, protected the ioun stone from harm and theft while still providing its full powers to the owner.

Binding a stone to a single owner is a lengthy process. To begin the ritual, the owner meditates with but a single stone in orbit around him. The body must be cleansed by fasting for a period of at least 3 days. If the fast is broken or interrupted, the process must begin anew. At the end of the fast, the owner makes a DC 20 Charisma check; taking 10 is not permitted on this check. Success indicates the stone has bonded with the owner, and may be implanted. Extending the fasting increases the chance of bonding with the stone, but the character may suffer the effects of starvation and thirst if he persists after several failures; the character gains a +1 circumstance bonus to the Charisma check for each full day past the third spent in fasting, to a maximum of +5. Failing the check means the owner must start over.

Once the owner establishes this bond with the stone, he can have it implanted in his body, which takes 1 hour. This requires a DC 25 Heal check (with a –5 penalty if the owner is the one performing the surgery) and a DC 25 Knowledge (arcana) check to succeed. Failure inflicts 1d6 points of Constitution damage and means the implantation process must start again. Success binds the stone on the surface of the owner’s skin in a location of his choice (usually the head, arm, or hand), where it becomes one with the owner’s flesh, deals him 1d2 points of Constitution damage (which he can heal naturally or with magic), and gives him the full benefits of the ioun stone. Once implanted, an ioun stone may not be sundered or targeted by effects and cannot be removed without the owner’s consent while he is alive (barring complete removal of the implanted body part).

Rumors exist of stranger, darker magics that allow spellcasters to channel spells through their implanted stones, or that cause the stones to shatter if the owner is killed, but those with any actual knowledge of these procedures are dead, hidden, or not talking.

Inferior Ioun Stones

There are very few reports of ioun stones that have negative side effects; even those created by incompetent item-crafters merely create inferior specimens—still valuable to poor adventurers who cannot afford the normal variety. They fall into one of the following categories.

Cracked: These stones bear an obvious crack, whether as a result of the crafting process, because the raw stone was already cracked, or because the stone has been damaged (for example, if it gains the broken quality). A cracked stone’s power is usually the same as an undamaged stone, but weaker.

Flawed: These stones have a flaw other than a crack, such as irregular faceting or impurities in the crystal. A flawed stone’s power is usually similar to and weaker than a normal ioun stone, but sometimes it has side effects or slightly different effects than its normal counterpart.

Scorched: These stones are depleted somehow, but not so much as to render them completely burned out and powerless; some achieve this state from damaging exposure to extreme heat or electricity. A scorched stone’s power functions erratically (typically a 50% chance per day for constant-effect items, or 50% chance per use for use-activated items) but is essentially the same as an intact stone of the same type. For example, a scorched pearly white spindle ioun stone might give the wearer a 50% chance per 10 minutes to regenerate 1 hit point.

Cursed Stones: When a magic item creation skill check to create an ioun stone fails by 5 or more but less than 15, there is a 50% chance the result is a cracked stone and a 50% chance the result is a flawed stone. If the check fails by 15 or more, the stone is actually cursed; roll on Table: Common Item Curses to determine the effects of the stone’s curse.

Resonant Powers: When an ioun stone is set within the special indentation in a wayfinder, a secondary resonant power sometimes manifests to augment the ioun stone’s powers, though this suppresses the wayfinder’s normal magical abilities. This minor function is in addition to the stone’s normal abilities, which continue to affect the wayfinder’s bearer as though the stone were orbiting her head. Two resonating wayfinders wielded by the same character suppress one another’s abilities, but both return to normal when one wayfinder is set aside. 75% of ioun stones grant resonant powers when placed in a wayfinder. 25% of cracked or flawed ioun stones have resonant powers (see Wayfinders and Ioun Stones) compared to the 75% chance for typical ioun stones; only 10% of scorched ioun stones have resonant powers.
