Paths Seldom Trodden has relatively few uses for Nazgul, as their preferred sites are all very early on the site path. Additionally, the cost of using this card is relatively expensive and it does not help sites that trigger when the fellowship moves there (such as Eregion Hills). Since it only requires a Nazgul to play, it might have some use with later sites such as Tol Brandir, but if the opponent is ahead then it will likely be the user's site anyway.

Paths Seldom Trodden can be used to assist a Silinde/Uruviel fellowship, by guaranteeing that the player gets the site that they want. It could also have more use in games with three or more players.
