I have a tame Nightmare that I tamed probably in 1999 maybe 2000. I was away from the game for several years and missed alot of the changes to taming and pets. I understand that this "type" of Nightmare may no longer be available. Is this true? I have also noticed that when Loring said Nightmare all resistances are listed as a numeric value except for Physical. Physical resist simply denotes: --. What if anything does that mean?
