Shardblade
Shardblade: Drow Longknife +4
Keen: This ability doubles the threat range of a weapon. For instance, if it is placed on a longsword (which has a normal threat range of 19–20), the keen longsword scores a threat on a 17–20. Only piercing or slashing weapons can be keen. (If you roll this property randomly for an inappropriate weapon, reroll.) This benefit doesn’t stack with any other effect that expands the threat range of a weapon (such as the keen edge spell or the Improved Critical feat).
Moderate transmutation; CL 10th; Craft Magic Arms and Armor, keen edge; Price +1 bonus
Returning: This special ability can only be placed on a weapon that can be thrown. A returning weapon flies through the air back to the creature that threw it. It returns to the thrower just before the creature’s next turn (and is therefore ready to use again in that turn). Catching a returning weapon when it comes back is a free action. If the character can’t catch it, or if the character has moved since throwing it, the weapon drops to the ground in the square from which it was thrown.
Moderate transmutation; CL 7th; Craft Magic Arms and Armor, telekinesis; Price +1 bonus.
Ghost Touch: A ghost touch weapon deals damage normally against incorporeal creatures, regardless of its bonus. (An incorporeal creature’s 50% chance to avoid damage does not apply to attacks with ghost touch weapons.) The weapon can be picked up and moved by an incorporeal creature at any time. A manifesting ghost can wield the weapon against corporeal foes. Essentially, a ghost touch weapon counts as either corporeal or incorporeal at any given time, whichever is more beneficial to the wielder.
Moderate conjuration; CL 9th; Craft Magic Arms and Armor, plane shift; Price +1 bonus.
Wounding: Wounds caused by this weapon can not be healed magically.
Description: The blade is crafted from a shadowy crystal with glimmers of opalescent light swimming constantly in the faceted blade. The hilt is of black bone wrapped in Adamantine wire. It bears no inscription or inlay.
