I read this as the TN for fear tests are doubled with the Denizen of the Dark. I know it has been established that only rolls are affected by the ability, but this quote seems to justify, that for the Nazgul, it also applies to Fear TN's. Otherwise there is no increased Fear inspired by the Nazgul in the darkness...In gaming terms, this lesser stature is reflected by the
three Nazgûl’s Attribute levels; theirs is a relatively low
value – even if at night it is doubled by their Denizen of the
Dark ability (the physical power and the fear inspired by
the Nazgûl is enormously increased in darkness).
Any comments?
