Sannleikur

The attuned creature cannot unattune from the Sannleikur until they die or they strike out one of
their own eyes. As an action, the attuned creature
can focus and see through the eye. Doing so
allows for the attuned to see the aura of every
living creature within line of sight (30ft). This
aura is marked by the greatest transgression of the creature and the sin that most afflicts them.
The sins are: Lust, Gluttony, Greed, Sloth,
Wrath, Envy, Pride.
