Blood Blade Ritual

The Blood Blades ritual is considered one of the more "questionable" rituals. Frankly, it is a forbidden ritual in various schools of magic and is a capital crime in many a nation.
It requires the sacrifice of a being and as such is widely considered as being something "evil".

The ritual is used to create a weapon that is attuned to a specific person's magical aura. This allows the weapon to inflict much more damage, the wounds are much harder to heal and all magic protective or healing magic used by this person is vastly reduced in effectiveness against this weapon.
