Abyssal Depths logbook diorama

The Abyssal Depths are located within the crust of Petrichor V, and is a part of the fourth set of Environments in Risk of Rain 2.

A hellfire-forged zone of blazing heat, the Abyssal Depths are believed to be a continuation and adaptation of the Magma Barracks from Risk of Rain.



  • All Multishop Terminals that spawn will be of uncommon rarity.
  • Shrines of Blood will not spawn on this stage.

Legendary Chest

A Legendary Chest will always spawn in the center of the environment, nestled between the rock faces in a nook behind some plants.

Broken REX

A broken robot can be found on the high up platforms of the stage. Interacting with it while equipped with a Fuel Array.png Fuel ArrayBgEquipment.pngFuel Array.pngLooks like it could power something. EXTREMELY unstable... will complete the Power Plant challenge and unlock REX.png REX as a playable survivor.

Newt Altars

The Newt Altars can spawn at several locations within the Abyssal Depth:

  1. Atop the hanging orange crystal in the center of the environment
  2. Corner of the third elevation level near the chain impalement
  3. Within a cluster of yellow crystals within the cave, which is only sometime accessible though the intentional means.
    • Can be accessed regardless by following the drop-down path entrance until the door and simply leaping over it with any movement abilities
