Cold Light of Day

What wears another's face cannot hold it when your light falls true.

(ongoing) All in your light appears as it really is, without the benefit of illusion, shapeshifting, or disguise.

Reduced: it lasts only a few moments, just long enough to glimpse the truth.

Empowered: illusions in the light are dispelled and shapeshifters in the light are momentarily stunned.
