404 Block

The 404 Block is a secret block that can be accessed on floor 16 of Bottom Block. This name is not official, and has been made by the community. There is not much to do here, and only has one floor. (Do note that if you have the Passive Ability "Endure" it will softlock the game, as it leaves you at 1hp and doesn't progress after that point)
== Floors ==
There is only one floor in the 404 Block, that being Floor 0. There are no stairs anywhere in 404 Block, so advancing to higher floors is impossible.
== Enemies ==
There is one enemy encounter found in 404 Block, and this enemy is a scripted fight. It's name is "?????", you cannot damage it, and it's only attack is to teleport right into your face in a jump scare effect, and set your HP to 0. 
However, the fight is currently broken, and will result in a softlock as "?????" does not spawn, and Hax do not work. [Note: This will be fixed in the next major update to the game, as confirmed by enzo on a developer stream.] [Confirm?]
== Names ==
The official name for the 404 Block is a jumbled seemingly random string of Unicode characters, so using that name here would be next to impossible. The community first named it "The White Floor" due to the fact that it was an empty white room with just the battle trigger. During the Pre-release v1.26.3, the 404 Block was not white and was instead a black void. This was confirmed to be a bug, and was fixed. That prompted the "White Floor" name to be changed to the 404 Block, a Block considering the game considers it it's own block in The Stack.
