This spell acts the same compared to continual light, as secret light does compared to light. Preliminary research seems to indicate the spell requires at least an ounce of blood from the wizard.
It also seems that it would be possible to make a magical lantern, whose light would only be visible to the person holding it. The exact process of its manufacture is not very clear, however, and the spell has been reported to fail regularly.
