Rotten Vale is a Location in Monster Hunter World (MHW). Different areas of the game have a different look and feel, map and special unique monsters that spawn within them.

Rotten Vale is a poisonous and hazardous area of The New World. Bones and corpses pile up, generating toxic fumes that are extremely harmful to Hunters and render even docile Monsters aggressive, and an entire ecosystem revolving around decomposition. Venture into the depths of the Rotten Vale in your journey to unravel the mysteries of the Elder Crossing.

Rotten Veil Trivia

  • A good portion of the Vale explored by the player is composed of the skeletons of two extinct monsters that are said to be related to Dalamadur. One of their skulls can be seen in the top Rotten Vale, and in the map. The upper levels of the Veil are made out of the skeleton, and the skull is visible from the entrance of the area 1 basecamp, looming above area 4.
  • An intact Rathian and partially intact Diablos can be found in area 6. They cannot be carved and are merely part of the environment.
  • Occasionally, faint unidentified monster growls can be heard in area 16, despite there being no monsters around.

      There's another giant (Dalamadur?) skull in the bottom of the zone too just outside Vaal Hazak's lair, forming the wall to the right of the acid pond he walks out of.

          The quest to get access to zone 10 from zone 2 requires you to talk to the head researcher, once you have access to the quest "Into the Bowels of the Vale" you should have access to the shortcut.

            Good question, so if you see an opening in the higher levels of the rotten vale between area 3 and 4 at the cliff, It leads you to area 10.

                  i always thought all the bones were just random till my sister told me what the big ass skull was from, and i found the diablos on my own literally caught me so off guard, i just saw the familiar horns and i was like 'wtf??' thus beginning my hunt for more monster bits. i havent seen the rathian, so at least i have something else to do there (also me me big ***** baby, the first time i was in the rotten vale, i was so scared cause of all the nasty ambiance lmaoo)

                    Kinda grosses me out, thinking about how that Dalamadur was just rotting there for a while. Like at some point that thing had flesh on it, and now it doesn't, s o-
                    Couldn't stop thinking about that when I got a good look at the skull and saw all the drippy nastiness, but h e y

                      I've seen this twice now, so I know I'm not imagining it: While on High Rank expeditions in the Rotten Vale, when Odogaron was heading for his secret shortcut to his den, he was suddenly accompanied by a small, black dragon creature with wings folded, crawling on four short legs. It's hard to see detail, but it looks like Toothless from How To Train Your Dragon. The second time I saw it, I was using a bow, and I was able to shoot it a few times, but my arrows passed through it without damaging it. After it goes through the passage with Odogaron, it can't be found again. Has anyone else seen this? What is it? It looks nothing like any other monster I've encountered. This is prior to XenoJiva.

                        Go down to Area 14, and you'll find what I think is a smaller Dalamadur skull/mouth connected to the ceiling.

                          Saw a tail bone that looked very much like a Ceadeus tail here. Dunno how the big beardo would get here, but he is an elder dragon, so maybe?

                            Has anyone else noticed the blue glowing slime/bone balls behind the vines in area 12?
                            They reminded me of Nakarkos' glowing.
