This spell makes a weapon magically keen, improving its ability to deal telling blows. This transmutation doubles the threat range of the weapon. A threat range of 20 becomes 19–20, a threat range of 19–20 becomes 17–20, and a threat range of 18–20 becomes 15–20. 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. (Treat shuriken as arrows, rather than as thrown weapons, for the purpose of this spell.)
The effects of this spell stack with the benefits of the Improved Critical feat. (Remember that two doublings is a tripling, etc.) They do not, however, stack with the effects of the keen weapon property.
You can’t cast this spell on a natural weapon, such as a claw.
