Gloomfeeder

Gloomfeeder (Korean: 어둑시니, eoduksini) is an NPC that first appears in Yakgwa Village: Haunting Tales update's event game mode and story, Yakgwa Village: Haunting Tales. While Gloomfeeder does not have any sprites story-wise, it takes the role as one of the monsters that needs to exorcise.

Gloomfeeder was added as a Raid Run boss in the first half of the Trip to Paradise update.

Trivia

 * Gloomfeeder makes an appearance in Gim Cookie's Ghost Index 👻, with a description that reads as such:
 * A ghost dwelling in the shadows thrives on the fears of Cookies, gradually swelling in size. If you keep your gaze fixed on it, it'll expand, flattening the Cookies. While it's possible to ignore the darkness, once you start to fear it, that fear might consume you.
 * As its Korean name suggests, Gloomfeeder is based on the eoduksini (어둑시니), a shadowy entity in Korean folklore that grows in size the more it is looked upon. The eoduksini is not quite a ghost, being more like a personification of darkness itself.
