I'd appreciate it very much if someone could tell me where to find or buy a Massive Myrad Bone. Plan A was to kill the wild black myrad, but that didn't go so well. Or perhaps the item code?
you might have to look into CK to find it. Or you could try opening the console and typing 'help myrad' - I've no idea if it will work, but it should list anything with 'Myrad' in its name, including the bone you need. I have, however, no clue as to the unintended consequences doing this might have...
Otherwise, there are some wild Myrads in the game, so happy hunting. They are rather mean, though, as you have noticed.
