Miasmars are threats found in the remotest places of the world; further, they have a natural affinity for magic. They are mindless creatures, feeding on the negative emotions of mortals.
A miasmar is a creature of mist and shadow; like an evil fog, it rolls and swirls across the land. Its presence is dark and chilling, and its hunger is boundless.
Miasmars will aggress on anything they encounter; they move across the landscape seemingly without direction. When they encounter prey, they will immediately begin instilling fear, and feeding off all negative emotions; they do this by covering as many victims as possible (miasmars do not make any attacks).
A miasmar takes up all nearby area. Any character that starts their turn inside the miasmar suffers d6 damage, and the miasmar is healed for d3 damage.
