Walkthrough
  1. 1

    • Method 1: Wardenfly Capture
      • Find Wardenflies in areas like Deep Docks (requires Cling Grip) or Bilewater (Faydown Cloak recommended).
  2. 2
    Allow the Wardenfly to spit its goop at you to become incapacitated.
  3. 3
    The Wardenfly will then use its cage to transport you to The Slab.
  4. 4

    • In Act 2, access Choral Chambers.
  5. 5
    In the southwestern corner of Choral Chambers, a long bridge leads directly to The Slab.
  6. 6
    This method allows you to retain all your items.
  7. 7
    Escaping the Cage:
    • Once transported, wiggle your controller to break free from the cage.
  8. 8
    Note that most of your equipment, including Crests, will be taken. You will have a basic weapon, basic healing, and your abilities (wall jump, dash) but not your cloak (cannot float).

    Finding the Key of Indolent:
    • Head to the bottom of the main area and enter the room on the left.
  10. 10
    Break the ceiling directly above the locked door.

  12. 12
    After falling down a chasm, go right to find Grindle (who offers no help).
  13. 13
    To the left, at the end of the hall, strike the item hanging from a chain to obtain the Key of Indolent.
  14. 14
    Return right and use the key on the locked door.

    The Slab Map and Benches:
    • You will enter the main vertical area. Going up allows you to break the ceiling on the right for a shortcut.
  16. 16
    The first door on the left (upwards) is locked by the Key of Indolent.
  17. 17
    Continue down to the lower area and find the room with the bench sign. The first Bench is located behind Grindle.
  18. 18
    Continue right from the bench to find an opening in the wall.
  19. 19
    Inspect the body at the end of this tunnel to get the map for The Slab.
  20. 20
    Return to the vertical corridor and head to the bottom.
  21. 21
    Go right to find a room with a locked door (requires Indolent key) leading to a monster arena with traps.

    • From the second Bench, continue down to a room with enemies below.
  27. 27
    Initiate an attack to trigger a battle arena.

    Defeat all enemies in the arena to obtain the Key of Heretic.
