" When Revealed: Starting with the last player, each player must either return a Nazgûl enemy engaged with him to the staging area or make a Hide 2 test."
Can we just choose to return a Nazgûl enemy, even if not engaged with one, and just ignore the ones in the staging area?
Or is it implied that we must make a Hide 2 test if not already engaged with a Nazgûl?
If the latter is the case I really wish they would have worded it like "each player must return a Nazgûl enemy to the staging area. If not engaged with a Nazgûl the player must instead make a Hide 2 test"
