The Sihedron is a seven-pointed star that symbolizes the power of rune magic. Each of the Sihedron’s arms is made of a different skymetal. The powers granted by the Sihedron are greatest when it is used not by a lone individual, but by a group that works together toward a common goal, and whose members trust each other enough to effortlessly pass control of the powerful item between themselves swiftly and without a second thought.
The Sihedron is a relatively plain-looking item. The seven different hues of its composite metals help to give it some color, but the artifact lacks any of the decorative runes and markings.
Once the Sihedron is activated, it glows with a warm yellow light that sheds illumination as if via a daylight spell. To activate the Sihedron, a person need only touch the center of the star where all seven arms meet and concentrate as a swift action—the Sihedron immediately rises up into the air behind the user’s head like a halo and floats along behind him wherever he goes, even teleporting along with him. Although the Sihedron is not in physical contact with the user, it is in all ways treated as if it were an attended object being held or carried. The Sihedron implants knowledge of all its powers and how to activate them into the mind of anyone who activates it in this way.
Once activated, the Sihedron protects its user in a number of ways. First, it constantly infuses the wearer with magical energy, granting him fast healing 5. Second, it grants the user the constant effects of a foresight spell (providing a +2 insight bonus to AC and on Reflex saves, and preventing the user from ever being surprised or flat-footed). Third, up to once per day, the Sihedron can target its wearer with true resurrection the instant he is slain—he need not activate this power, as the Sihedron automatically triggers if the user is killed.
When the user activates the Sihedron, he may select one of the star’s points to be “ascendant.” The Sihedron rotates so that this point is pointing upward, and he immediately gains an additional defense and the use of a spell-like ability, usable at will, as detailed below. The user may change which point is ascendant as a standard action by concentrating, but cannot change the point to an “oppositional” point. The effects granted by each of the Sihedron’s points (as well as the two oppositional points for each) are listed at the end of this item description.
As an immediate action (but no more often than once during any single combat round), the current user of the Sihedron may cause the artifact to instantaneously transfer itself to another willing creature within 120 feet. The Sihedron teleports from the current user and appears behind the head of the target creature. As it does so, it unleashes a surge of potent magic that affects both of these creatures, granting a +2 insight bonus on all saving throws for 1 round and healing each creature of 2d8+10 points of damage. This transfer occurs so quickly that it can grant the bonus on a saving throw after the saving throw itself has been rolled, but it must be made before the result of that role is confirmed by the GM. Likewise, the healing granted can occur in the instant before a creature actually takes damage from any source, which could heal a heavily wounded target before the additional damage renders it unconscious or even kills it. When the Sihedron is granted to a new target in this manner, the new target can automatically select which point of the Sihedron is ascendant, even if the point selected is oppositional to the previously active point.
Each of the Sihedron’s arms contains an ioun stone embedded in a small receptacle. These ioun stones cannot be removed as long as the Sihedron is whole, and they help to power the following additional abilities when one of the points is ascendant.
The Sihedron must be crushed under the foot of an oliphaunt while it is being used by a character who willingly allows himself (along with the Sihedron) to be so destroyed.
