The Rotten Vale (Japanese 瘴気の谷) is a location first introduced in Monster Hunter: World. This area is an inhospitable valley littered with the corpses of dead monsters.

Description

The Rotten Vale is a massive area covered in the rotting bones of Elder Dragons and other monsters that have come there to die. It sits at the bottom of the Coral Highlands, though perhaps it is more accurate to say the Coral Highlands grows from the Rotten Vale.

Environments

The Rotten Vale can be divided into three sections; the third being much smaller in size.

Upper Section

The upper area near the starting camp is fairly open and mostly inhabited by Radobaan, Hornetaur, and Vespoid. It is mostly made up of large bony structures.

Deeper Section

The area that can be reached by jumping from the upper section has numerous Girros. Of course, their leader Great Girros lives here, while Odogaron and Radobaan can also be found in the upper and deeper portions of this zone, respectively. In addition, the second camp is located in this section. Effluvium is a big problem from the first portions to the deepest parts of this section. The corpses of Raphinos and, very rarely, Legiana will occasionally fall to this area.

Acid Pools and the Depths

The depths of the Rotten Vale has acid that can damage hunters. The dens of Odogaron and Vaal Hazak can be found here.

Notes

• The apex monsters of the Rotten Vale are Odogaron and Tigrex.
  • Though both monsters are considered to be the apexes of the Rotten Vale, Vaal Hazak is considered to be the true ruler of that ecosystem.
• The Rotten Vale has a deadly gas that can suffocate hunters. Called Effluvium, it is produced by a bacterium that causes dead tissue to rot rapidly. When a Hunter is exposed to Effluvium, their maximum health will be reduced.
  • This gas also makes the monsters that live in the area more aggressive than usual, even timid ones.
• Giant bone structures hang above some areas that a hunter can bring down upon monsters using their Slingers.
• Above the Rotten Vale is the Coral Highlands.
• Hunters can carve the corpses of monsters in the Rotten Vale like Legiana.
• A good portion of the Vale explored by the player seems to be made from the corpse of a Dalamadur. Its skull can be seen in the top Rotten Vale, and in the map.
  • The head can be seen at the Base Camp.
  • its eight tails can be seen throughout the Rotten Vale.
  • One of the paths in the Rotten Vale that can traveled upon, is the spine of Dalamadur
  • Two meteors can be found in the Rotten Vale, which explode into blue flames once destroyed. This suggests they are the remains of Dalamadur's Shattered Omens.
• The Rotten Vale has acid puddles that damages those who stand in them.
• The Rotten Vale is the graveyard for monsters, including Elder Dragons. Monsters come to this area to die.
• Upon dying, the Elder Dragons dissolve in the effluvium, and their bioenergy accumulates in the earth before eventually crystallizing. This process made the crystalline structures seen in the Elder's Recess and Confluence of Fates.
