Wayfinders and Ioun Stones

Within each wayfinder is a fine lattice of wires that serve to channel the power of ioun stones, allowing the owner of a wayfinder to benefit from a stone's power without the attendant risk of having a valuable item orbiting around her head. In addition, the magic worked into the wayfinder amplifies the power of the ioun stone, usually (about 75% of the time) unlocking new abilities in addition to the stone's normal power. Unfortunately, the energy required is such that the magical properties of the wayfinder itself are diverted to power the ioun stone, temporarily negating the wayfinder's normal abilities. The mechanism of using a wayfinder to boost the power of an ioun stone is usually called augmenting, channeling, enhancing, or resonating.

The resonant aura of a wayfinder interacting with an ioun stone can be detected and identified with detect magic (or similar spells) and the Spellcraft skill, just like any other magic item.

The auras of multiple augmenting wayfinders tend to interfere with each other; a person with one who tries to hold or carry a second usually finds that both sputter out in just a few seconds, but activate again once the second one is set aside. Some advanced, expensive wayfinders may hold more than one ioun stone at the same time and still function (though another wayfinder can interfere if brought too close).

To determine what effect a wayfinder has on an ioun stone, select one of the following methods.

Method 1, The Static Assignment: All ioun stones of a particular color and shape react exactly the same way to all wayfinders. This is the easiest and fastest method, but lacks variety and allows the PCs to easily predict what a new stone or device will do when combined. For a listing of these combinations, see below.

Method 2, The Random Roll: Each combination of an ioun stone and a wayfinder requires a roll on a table to see what resonant power it gains. This methods allows for a lot of variety but requires bookkeeping to track each unique stone's augmented power, and also makes it difficult for the PCs to predict what any particular combination may be. See the table on page 53.

Resonant Powers (Method 1)

The resonant powers of the most common forms of ioun stones are listed below. If the power is a feat, the bearer gains that feat as a bonus feat even if he does not meet its prerequisites.

Spell effects with uses per day are spell-like abilities.

Agate ellipsoid: Increases the caster level of divination spells by 1.

Amber spindle: 5% chance per Reflex saving throw of granting the wearer evasion against that effect; bonuses from multiple amber spindles stack.

Amethyst ellipsoid: +2 circumstance bonus on Stealth checks against undead.

Clear spindle: Protection from possession and mental control (as protection from evil).

Crimson sphere: +1 competence bonus on single Knowledge skill (chosen by the stone's creator).

Dark blue rhomboid: The wearer no longer suffer penalties on Perception checks for being distracted or asleep; during sleep the wearer may remain open-eyed and fully aware of his environment, though he is still helpless against undetected threats until he actually wakes up.

Deep red sphere: Improved Unarmed Strike.

Dull gray stone: Read magic 1/day day for 10 minutes.

Dusty rose prism: +2 insight bonus on CMB and to CMD.

Emerald ellipsoid: 5 additional temporary hit points.

Gamboge nodule: +2 resistance bonus on saving throws against disease.

Gold nodule: +1 bonus on saves against language-dependent effects.

Incandescent blue sphere: Blind-Fight.

Iridescent spindle: Endure elements, as the spell, as well as protection against exposure to vacuum and underwater pressure.

Lavender and green ellipsoid: If the bearer is holding the wayfinder, he may use the stone's absorption ability as an immediate action instead of a readied action.

Magenta prism: +1 bonus on one saving throw not modified by the ability score the stone is currently attuned to (chosen at the same time as the ability score).

Mossy disk: +1 competence bonus on Appraise checks.

Mulberry pentacle: +2 competence bonus on Sense Motive checks.

Nacreous gray sphere: Miss chance against incorporeal creatures decreases to 25%.

Onyx rhomboid: Virtue at will (self only).

Opalescent white pyramid: Weapon Focus with the stone's keyed weapon.

Orange prism: Every time the bearer casts a spell, roll 1d4–2 and add this (and the +1 caster level granted by the normal power of the ioun stone) to his caster level. If this modified caster level is too low to cast the spell, the spell fails and is lost.

Pale blue rhomboid: +1 bonus on Fortitude saves.

Pale green prism: Twice per day as a free action the bearer may remove the fatigued condition from himself as a free action (or reduce the exhausted condition to fatigued).

Pale lavender ellipsoid: If the bearer is holding the wayfinder, he may use the stone's absorption ability as an immediate action instead of a readied action.

Pale orange rhomboid: A soul held within the stone can remain there indefinitely as long as the wayfinder remains on the soul's original body. If the wayfinder is removed from the body, the ioun stone's resonant power is suppressed until the wayfinder is replaced.

Pale ruby trillian: Increase by 10 feet the distance the bearer may fall safely (stacks with other effects that increase this distance, such as making Acrobatics checks or falling into water).

Pearly white spindle: +1 sacred bonus on saves against attacks that rely on negative energy.

Pink and green sphere: +1 bonus on Will saves.

Pink rhomboid: +1 bonus on Reflex saves.

Scarlet and blue sphere: +1 bonus on Will saves.

Scarlet and green cabochon: +5 bonus on Constitution checks made to stabilize.

Silver Spindle: All spell-like abilities granted by race are treated as 1 caster level higher.

Tourmaline sphere: +1 bonus on Constitution checks to stabilize when dying.

Turquoise sphere: +2 competence bonus on Handle Animal checks.

Vermilion rhomboid: Breathe water for up to 10 minutes per day, useable in 1-minute increments.

Vibrant purple prism: The bearer may use a standard action to expend one stored spell level in the stone, refreshing a cast 1st-level spell as if using a pearl of power.

¹ If the stone's normal power gives the same kind of bonus, these effects stack. For example, a deep red sphere (+2 enhancement bonus to Dexterity) that has the resonant power of “+2 enhancement bonus to Dexterity” gives a +4 enhancement bonus to Dexterity.
² Optionally, a wayfinder with multiple spaces for ioun stones may only be damaged at one of those locations, and other ioun stone slots work normally.
³ If no appropriate target is within range, the needle points north as normal.
