Elden Ring Nightreign director Junya Ishizaki has confirmed some big changes are coming to the Soulslike’s map, including the return of every player’s favorite swamp terrain. The base game’s Swamp of Aeonia left a stain on the Tarnished's memory, located in the sub-region of Caelid and home to enemies like Abnormal Stone Cluster, Servant of Rot, and the Commander O’Neil boss. Therefore, fans will be approaching Elden Ring Nightreign’s swamps with extreme caution.
