Mirror Effect

Mirror Effect is a magic spell which Visenna uses to kill the koshchey in the short story "Droga, z której się nie wraca". It is not a reflection spell in the traditional sense, but more of a parabolic mirror effect, a concentration of the sun's rays onto a specific target. The beast is said to explode quite spectacularly from the effect of the spell.
