This spell turns an ordinary edged melee weapon into a blade of sharpness, as per sword of sharpness (see the Dungeon Master's Guide, page 186). For the duration of the spell, the weapon is treated as a weapon, +3 or better for purposes of who or what can be hit by it, even though it gets only a +1 bonus to attack and damage rolls. However, on a very high roll, it will sever an extremity, determined by a dice roll. The spell functions on existing magical weapons, as long as the total combined bonus is +3 or less.
The material component for this spell is a 1000 gp diamond, however, the tooth of a tarrasque may be substituted, in which case the weapon functions as a vorpal blade (see the same reference as above), and gets the +3 bonus to attack and damage rolls.
