The Necromancer Cloak is a rare drop from the Fire Scorpion. It is highly sought after by many players who are looking for a better armor than the Tropical Plate or Desert Shroud. It is the counterpart from the Necromancer Plate.
Most people claim that the Petalknight Cloak is better than the Necromancer Cloak because the Petalknight Cloak has 10 more health regeneration even though the Necromancer Cloak has 7 more defense. It is also an armor people use when they have not yet earned Level 33 for a Petalknight Cloak.
