Book of Vile Darkness 3.5
By Monte Cook
The caster changes a bone at least 6 inches long into a longsword, short sword, or greatsword (caster’s choice). This weapon has a +1 enhancement bonus on attacks and damage for every five caster levels (at least +1, maximum +4). Furthermore, this blade deals an extra +1d6 points of damage to living targets and an additional +1d6 points of damage to good aligned targets.
This spell confers no proficiency with the blade, but the caster doesn’t need to be the one wielding the blade for it to be effective.
Focus: A 6-inch-long bone.
