Jiggig

Jiggig is a place where dead Ogres were buried until they started to come back to life as undead, Zogre and Skogre. Ogres built a barricade to stop these undeads from escaping. Jiggig can only be entered during and after the Zogre Flesh Eaters quest. According to Grish, it is named Jiggig as it's where Ogres jig.

Undead ogres may disease a player. This can be countered with Relicym's balm. They are also very resistant to normal weapons, but Brutal arrows work on them very well.
