The Midnight Marauder is a special Fall holiday themed garb outfit. It was not in the original Pirates Online but added later to The Legend of Pirates Online.
This particular outfit is sold in pieces only by Jonathan Fairbanks at The Decrepit Shop in the Hollowed Woods. It is only available during the Halloween Event. The items are paid with bones found by killing enemies during the months of October and November.
The Midnight Marauder and Pumpkin Privateer are virtually identical except for the color scheme of red vs orange.
It was added in 2018 as part of the original Hollowed Woods update.
