  You imbue a slashing melee weapon with the ability to create a bleeding wound. As a Free Action when the weapon hits a living creature, the wielder can discharge this spell to add 1 point of bleed damage to the weapon's base damage. This bleeding is difficult to stop; add your spellcasting Ability Modifier (Wisdom for clerics, and so on) to the DC to stop the bleeding.
