Agara Nightmare Dungeon

Nightmare Dungeon (also known as Agara BD or Agara Bad Dreams due to its location) is a level 42-52 dungeon with a level cap to ensure that only those above level 42 may enter. It contains Jesters, Carrion Warriors, an Immense Flesh Corpse and is the only dungeon containing Flesh Corpses, and the Calamity Elder. Nightmare Dungeon also contains some Tribal Berserkers from Seryl Dungeon and the boss Vex the Bellicose.

Because of the large number of demonic essence dropping monsters and the monsters from Seryl Dungeon, this dungeon is the preferred place for leveling after level 42 and farming demonic essence. Unfortunately it is located on Agara, unlike Bad Dreams (BD) which is located to the right of OSL. Thus some people do still prefer to level at BD instead.

How to reach the dungeon
On the island of Agara (located on the lower left side of the map from osl) the Nightmare Dungeon is located inside the house to the left of the Agara Hedgerows flag. Just keep following the brown dirt path until you cross the bridge and it will be on the first building to your right. On the second floor of the building should be a white bed. If the player walks into the side they can climb in and "take a nap." The screen will slowly grow darker and darker until it teleports them into the dungeon. To leaves the player must go up two rooms and then follow the river to the right past the Immense Flesh Corpse. The first doorway they encounter from this river should have another bed which will bring players back out.

Locating the Bosses
The Immense Flesh Corpse is located in room 4, which is up and to the right of the entrance.

The Calamity Elder is located in room 3 which is up and to the left of the entrance.

Vex the Bellicose is located up and to the right of the entrance. After the player passes the Immense Flesh Corpse they should jump in the river and keep swimming until they reach him.
