Dire Weapon of Blood

This spell allows the caster to inflict 1d6 points of slashing/necrotic damage to herself by cutting herself with a weapon that she wants to become a weapon of blood. A weapon of blood becomes sharper, more menacing, and does more damage. Any slashing or piercing weapon (including natural weapons) where the blood is applied has its base die increased to the next die (a weapon that does 1d8 points of damage now does 1d10). The affected weapon will remain so until combat starts for 1 round + the character’s Constitution modifier (the one who gave the blood). This spell also inflicts 1d4 temporary Wisdom point modifier damage when activated.
