You create an aura of divine light around yourself with a radius of 5 tiles that lasts for as many minutes as your Phosmagus level. Creatures within this aura must succeed an Arcana check when they attempt to speak a deliberate lie or else be unable to speak that falsehood. Creatures that succeed this check feel a momentary discomfort but can speak as they wish. You know when a creature has resisted this effect, but not what truth they are concealing.

In combat: Once per combat · Out of combat: Once per hour
