— Ocanthicite Weapon:
All ocanthicite creatures possess some form of weapon constructed from the black ice of the infamous Ocanthus barrier. This weapon usually takes the form of a one-handed or two-handed blade of a size appropriate to the ocanthicite creature. This black ice is much colder then normal ice. When an ocanthicite creature handles it, the substance becomes strong enough to be forged like steel.
If the ocanthicite creature is destroyed, its weapon is also destroyed unless the weapon succeeds on a DC 19 Fortitude save. If the weapon is destroyed while the ocanthicite creature still lives (such as through a successful sunder attempt, or the disintegration spell), the ocanthicite creature may attempt to reform it as a full-round action, which provokes attacks of opportunity. Doing so imposes a –4 penalty to the creature’s Constitution for 1 hour, as it must sacrifice of its own essence to rebuild the weapon. An ocanthicite creature may only have a limited number of ocanthicite weapons, according to its entry. Any attempt to create more beyond this number automatically fail, but the ocanthicite creature still suffers the Constitution penalty for attempting to do so.
Any item made of ocanthicite is supernaturally cold. Any creature struck by an ocanthicite weapon is dealt 1d6 points of cold damage and 2 points of Wisdom damage each round it remains in contact with the ore. A successful DC 12 Will save negates the Wisdom damage. Creatures with the Cold subtype are unaffected by the Wisdom damage. Ocanthicite has hardness 10 and 20 hit points per inch of thickness.
Creatures with at least 6 points of cold resistance may ignore the cold damage, but only creatures with the Cold subtype may ignore the 2 points of Wisdom damage. An ocanthicite weapon, regardless of that weapon’s source, can never harm an ocanthicite creature.
Ocanthicite responds especially well to magical enhancements (such as frost and icy burst) that increase its ability to deal cold damage. It costs 10% less to apply such enhancements to an ocanthicite weapon.
