Curse eyesight

When this spell is cast it makes the target eyes turn a sickly deathly purple and their Iris rapdily moving causing pure blindness of the highest degree while infecting their eyes with an evil pision. For this spell to be cast the user must cover the pair of a blind man's eyes with the purple dye then make a spell circle infront of you before throwing the eyes in then stabbing the eyes and the spell circle with a knife while saying the words "Rectores magicae et mortis inficiunt oculos suos morte visus et sanitatis pro annis futuris(rulers of magic and death infect their eyes with death of sight and health for the years to come)". This can only be undone by a 6th level or above healing spell.
