Hub 4: Gibbet



The Gibbet is one of the maps accessed from Hub 4: Castle of Grief (map). This is almost like a sub-hub in itself. From here, you can access Hub 4: Effluvium and Hub 4: Dungeons.

Walkthrough
The level itself is a killing floor connected with an underground library, dungeon, balcony, throne room, and hypostyle hall (where the headless statue of Yorick lies). Beforehand, the player needs to have acquired two books, the Liber Obsura and the Daemon Codex, from Hub 4: Forsaken Outpost and place them in the empty book slots, thereby unearthing Yorick's Skull. Placing the skull on the shoulders of the headless statue creates a chain reaction that obliterates the floor all around the player (creating a long-falling death trap) and grants him entrance to the Effluvium level.

Bugs
There is a script on this map that requires a very specific condition to activate that the player can accidently render impossible to meet. The script must activate to allow further progress in the game.

In the room behind the Axe Door is a throne that four Chaos Serpents will teleport on to. The aforementioned script checks every few seconds that exactly three remain and lowers walls when the condition is met. However, it is possible for the player to reduce their number below three in those few seconds. In this case the script will never activate and the player will become permanently stuck.

This bug was fixed in the version of the script included in the Version 1.1 WADfile.
