The sky opens up and releases a brief and localized but very heavy downpour of blood red drops of rain. Everyone within a 30-foot radius of you takes 4d6 points of damage from the pelting rain, and angry red welts appear on their flesh wherever the raindrops hit. Those who fail a Fortitude save begin suffering the effects of the disease Red Ache. You are immune to both the damage and the disease from your spell.
