Ruined Wood-elven towers are rare structures that spawn in Mirkwood corrupted. They were once lively normal Wood-elven towers, but now are nothing more than forgotten memories of the greatness of Greenwood. About halfway up the tower, there are large, open doors facing each direction. These doors are often level with the canopy. These towers also have an underground level with a hole leading to a spider dungeon. The dungeons below the towers can contain very valuable loot.
