A flickering red fire bursts in the area you intended. Creatures in the area are outlined in the flame, some more intensely than others.
Outlined subjects shed light as torches. Outlined creatures do not benefit from the concealment normally provided by darkness (although a 3rd-level or higher magical darkness effect functions normally), blur, displacement, invisibility, or similar effects. In addition, if they fail a Fortitude save, affected creatures take 1d4 points of fire damage each round as their passions manifest as physically damaging fire. Creatures that make a successful Fortitude save take only half damage each round for the duration of the spell (minimum 1 point per round). Spellcasters affected by this spell who try to cast spells must make Concentration checks (DC 10 + half the continuous damage last dealt) each round as they take continuous damage from the spell. The fire created by this spell can be extinguished by normal means; doing so ends the outlining effect.
