Do you believe yourself to be strong?
A sub-dimension designed to prove your strength. Lower to upper-tier Husks, Demons, Angels, and blood-fueled machines appear here. Husks are an exception, as Supreme Husks exist and appear with a low probability. Health can be recovered through the blood spilled by Husks, Demons, Angels, and blood-fueled machines. Health is replenished at the start of every round.
A bare arena consisting solely of indestructible blocks. A square plot of land floating in the air, measuring 20m in width, length, and height. It is composed of 400 blocks across the horizontal and vertical axes. With each passing round, the height of the blocks shifts, creating a different terrain pattern. As rounds progress, the number of Husks, Demons, Angels, and blood-fueled machines increases, and higher-tier variants begin to appear. Upon death, your record so far is displayed, and you can attempt the challenge again.
