With this spell, you can trigger the insightful and baleful magic of a mandrake root.
When you pull it from its dark container, you and all other creatures within 15 feet must make a Will save against its scream.
Those who succeed gain a true seeing effect; those who fail behave as though affected by confusion.
Both effects last until the spell ends.
