Yegga also known as Assaura, Thaurwain, Batstrike or Bat´s revenge was a brown paste refined from the guano of the Yegga bat (see also Yeggarûkh), a vampire bat native to mild climates which usually fed upon cattle. It was prepared by leaching Yegga guano with strong lye, filtering, then allowing most of the water to evaporate.Well known antidotes against Yegga-Poisoning were the Taynaga and the Deathward.
