One of the Dagorlad Wraiths, Covetous Wisp is most frequently seen in corruption decks, as its text gives it the ability to add burdens fairly dependably. This Wraith is often seen in conjunction with Undead of Angmar, who can lower resistance, as well as other corruption related cards such as Dark Swooping Shadows, Sense of Obligation and Gates of the Dead City. Its ability does require twilight to use, which can weaken the minion when playing against choke decks, although Fellowships that use Followers may add twilight during the Maneuver phase. The minion is also weak to Archery, unless Barrow-Wight Stalker is in play. Because its ability only triggers when the Free Peoples player assigns it, some Fellowship Players may simply allow the Shadow player to assign the minion and thus evade the ability (This can be discouraged by Stooping to the Kill's Damage bonus) - this does not work very well with most alternate Ring-Bearers however, as the Shadow Player will likely add burdens simply by assigning the Covetous Wisp to said Ring-Bearer.

• Low resistance Ring-Bearers
• Alternate Ring-Bearers
• Followers, as many add twilight prior to assignment
• Large Fellowships (More twilight)
