Nightmare WB is terrifying and has 4 million Health. It spawns all kinds of Nasty Adds and I would love to see it go up against Cloverfield. It may be the most terrifying Elder Scrolls WB yet to Date and the Coolest. I do not see any ESO WB's taking down Nightmare whatsoever. What a Battle it would be vs Cloverfield. Swaths of Cities would be Leveled lol. They also seem to have some similarities. My Money goes on Nightmare in a close call!
