Corrosive Venom FS 30 Nora For the next 6 turns, all poison damage dealt to opponents is dealt as acid damage. If an opposing unit would become poisoned, it instead becomes scoured. Ta daaa, Less poison woes.
but, poison damage is meant to be amplified does it get amplified before transformation? and truth be told that's why tide master got thrown into the theme and other stuff that escaped my mind? the issue is the theme hasn't kept up? i recall poison elementals was a boss, now it's pretty much a joke (although most elemental are sadly)
