Description: This spell makes a weapon magically keen, improving its ability to deal telling blows. This transmutation increases the threat range of the weapon by one. A threat range of 20 becomes 19-20, a threat range of 19-20 becomes 18-20, etc. The spell can be cast only on piercing or slashing weapons. If cast on arrows or crossbow bolts, the keen edge on a particular projectile ends after one use, whether or not the missile strikes its intended target. Multiple effects that increase a weapon's threat range (such as the keen edge spell and the Improved Critical ability) don't stack. You can't cast this spell on a natural weapon, such as a claw.
