As you sing, translucent spectral skulls float down from the sky like falling snow.
Your song draws the energies of death and destruction down on your enemies. Each round, any enemy in the area takes 2 points of Strength and Dexterity damage. Subjects can attempt a Fortitude save each round to negate the damage, but a successful save does not prevent damage in future rounds.
