Serpentbane

Serpentbane is a +1 long sword, +4 versus reptiles, including dragons. It glows equal to a Light spell with a silvery-white light on command. The sword is fairly plain, but has an etching on both sides of the flat of the blade above the hilt showing a warrior stabbing a 15 foot long snake. It does max damage to reptiles on a natural 19 or 20.
