The Bayvak have an incredibly strong connection with nature. Due to the many toxic plants that grow around Bayvak homes, most Bayvak are completely immune to neuro-toxic and paralytic poisons, and sedatives often have a significant lessened effect. This poison immunity starts right from birth, and only gets better with age. What few resistances children lack, they gain from their mothers slowly over time.
Female Bayvak with children have been known to surround their nests with toxic nooskoton vines, which can instantly paralyze any being who pricks itself on the plant’s thorns.
