Frenzywind Stone

With enough force, anything can pierce through stone.

A shining stone that forms into jagged spiralling rock formations that rise up as pillars, frenzywind stone is a deadly material that rends and grinds down everythong around it due to its intense properties. This stone possesses the power to turn gusts of wind into hailing streams of slashes capable of cutting flesh and rending metal in large amounts, causing entire environmental deadzones wherever it rises out form the ground beneath it, other stone or metals often within the viscinity often end up smoothed to a shine by such vicarious winds.
Weapons, ammunition, armor, and other equipment made out of frenzywind stone that weights 70 lbs or more, cause an aura of slashing wind to manifest within a 10-ft. radius around the item, dealing 1d4 slashing damage + 1 point per the item's caster level + 1 point for every 5 lbs past 70 the item weighs to all creatures within the aura each round. Weapons, ammunition, armor, and other equipment made out of frenzywind stone otherwise function as if made out of stone except as noted.
Weapons Weapons and ammunition made from frenzywind stone doubles the threat range of a weapon and deals damage as if the weapon were one size category smaller. The increased threat range benefit doesn’t stack with any other effects that expand the threat range of a weapon (such as the keen edge spell, keen weapon property or the Improved Critical feat). If there are any other effects that expand the threat range of a weapon (such as the keen edge spell or the Improved Critical feat) or the weapon has the keen weapon property, instead increase the critical threat range of the weapon by +1. This bonus is applied after abilities such Improved Critical or the keen weapon property and cannot be doubled. Weapons and ammunition made from frenzywind stone also deal their damage as slashing damage instead of their original damage type.
Armor Armor made from frenzywind stone causes unwieldy and powerful winds that affect even the wearer. The wearer and all creatures within a 10-ft. radius of the wearer take a -4 penalty to acrobatics and fly skill checks. This powerful wind also weakens the strength of incoming blows, providing the wearer damage reduction of 2/piercing if it’s light armor, 4/piercing if it’s medium armor, and 6/piercing if it’s heavy armor.
Items not primarily of metal or stone are not meaningfully affected by being partially made of frenzywind stone.
