I encountered this void demon in Ter Mur today. I had never seen one like it before (tail and all). It was the toughest void demon I had ever seen, and I've spent a lot of time hunting them on several shards building new characters . Very fast, dispels summons quickly, and I never could kill it with just GM EVs. Is it the top of the evolutionary chain or something special to Sonoma, where I was building a new character?
