Blood Dagger

With the wave of your hand, a magical dagger enveloped in blood appears in your hand. 

It has the same properties as a normal dagger but has 1d6 slashing damage instead of 1d4 piercing. While you are attacking and enemy the enemy must make a CON (DC 10) saving throw, on a failed save the enemy takes 2d4 bleeding damage, on a succsessful save the enemy takes 1d4 damage.

While your enemy was inflicted with bleeding, you can take some of that blood to recast this spell as a bonus round, this can only be done twice per short rest.
