Crown of White Ravens

A crown of White Ravens is one of several items that grants its wearer the use of a maneuver. The crown's wearer need not be a martial adept, but knowledge of other maneuvers and ranks in the discipline's key skill give the wearer access to more powerful maneuvers.
Lore: Elf scholars insist that members of their race were the first to create crowns of White Ravens, and all other similar items, such as Desert Wind cloaks and slippers of the Setting Sun, are copies of the concept created by martial adepts of other races. This assessment seems plausible not only because all crowns of White Ravens seem to be fashioned in the elven style, but also because the crowns have the longest recorded history.
Description: Three types of crowns of White Ravens exist: novice, scholar, and master. Each looks like a crown of white alabaster, carved with delicate fluting and spindles that rise from it like castle towers. Novice crowns of White Ravens have the simplest appearance and the fewest spires, while a master crown of White Ravens bears more than a dozen towers and some highly ornate carvings.
Anyone can wear a crown of White Ravens, but to gain any benefit from it, a wearer must meet the prerequisite of the desired maneuver.
Activation: A crown of White Ravens requires a day to attune to its wearer once it is donned. After wearing it continually for 24 hours, the wearer must choose one of the White Raven maneuvers that the item can grant for which he meets the prerequisite. He then gains knowledge of that maneuver and can use it as long as the crown is worn. Should the crown be removed and then replaced, it requires another day to attune itself to the wearer before it can grant knowledge of any maneuvers.
Effect: A person who has worn a crown of White Ravens for 24 hours gains the use of a single White Raven maneuver for which he meets the prerequisite. The maneuver can be of a martial adept level up to the highest level the item grants. A novice crown of White Ravens grants a maneuver of up to 3rd level, a scholar crown of White Ravens grants a maneuver of up to 6th level, and a master crown of White Ravens grants a maneuver of up to 9th level.
Aura/Caster Level: Faint divination (novice), moderate divination (scholar), or strong divination (master). CL 5th (novice), 10th (scholar), or 15th (master).
Construction (Novice): Craft Wondrous Item, knowledge of a maneuver from the White Raven discipline; 1,500 gp, 120 XP, 3 days.
Construction (Scholar): Craft Wondrous Item, knowledge of a maneuver from the White Raven discipline; 7,500 gp, 600 XP, 15 days.
Construction (Master): Craft Wondrous Item, knowledge of a maneuver of the White Raven discipline; 22,500 gp, 1,800 XP, 45 days.
Variants: Eight variants of the crown of White Ravens exists, one for each of the other martial disciplines. Like the crown of White Ravens, each has a novice, scholar, and master version. In all respects, they function in the same manner as the crown of White Ravens does, except that each grants access to a maneuver from a different discipline and occupies a different place on the wearer's body.
Desert Wind Cloak: Desert Wind cloaks are the color of wind-blown sand, and they always shift and flutter as if disturbed by a breeze, even indoors and on calm days. Most bear decorative stitching around the edges in gold and red thread depicting flaming scimitars, picks that trail smoke, and maces that shine like the sun.
Devoted Spirit Amulet: The appearance of these amulets varies considerably, since each is constructed to serve a particular axis of alignment: chaos, evil, good, or law. Some even double as holy symbols. A Devoted Spirit amulet does not function for someone who doesn't share its alignment.
Iron Heart Vest: These heavy, leather vests are run through with tiny slivers of iron, which give them a dull sparkle. The iron resists rust, but Iron Heart vests can eventually take on an orange hue because the iron slivers degrade and stain the vest's material.
Ring of the Diamond Mind: Unlike similar items devoted to different disciplines, a ring of the Diamond Mind requires its creator to have the Forge Ring feat instead of Craft Wondrous Item. A ring of the Diamond Mind looks like a simple gold band set with a diamond, but anyone peering closely into the stone can see the visage of the wearer, or of the last person to wear the ring if no one currently wears it.
Shadow Hands: Shadow Hands look like hands carved of jet. The carvings are incredibly detailed, depicting every mark of a humanoid hand, down to fingerprints and every crack in the palm and knuckle. When someone places both hands over the Shadow Hands so that his shadow falls over them, the carved hands vanish, and a pair of black silk gloves appears on the person's hands. The gloves can be removed normally, whereupon they become hands carved of jet that look exactly like the wearer's hands.
Slippers of the Setting Sun: Each of these beautifully crafted red silk slippers bears an emblem of the setting sun upon the toe. The sun is stitched gold thread, and its rays are bronze and copper.
Stone Dragon Belt: A Stone Dragon belt looks like a wide belt made from expertly broken slabs of slate. Surprisingly, it weighs almost nothing and doesn't inhibit movement at all.
Tiger Claw Bracers: These bracers bear a tiger's stripes, but all in metal, with copper for orange, iron for black, and silver for white. Upon donning the bracers, the wearer hears a tiger's roar and feels the pain of sharp claws in his back for fleeting moment.
