Catacombs

Spoilers ahead! The Catacombs are a secret location in Dark Forest Apocalypse.

Accessing the Catacombs
To access the Catacombs, the player must check a specific wall tile located between the entrances to the Apprentices' Den and Nursery. The tile has a small, barely visible crack on it. When checked, the player will be prompted to attempt to break the wall. Attempting to break the wall will not consume Daylight Hours, but the wall will not break unless the protagonist's ATK value is 200 or higher (including weapons.)

The Catacombs can only be completed once, and cannot be accessed after level 10 is completed.

Completing the Catacombs
When entering the catacombs, the player will notice a large hexagram symbol on the ground. Scattered throughout the catacombs are eight Cave Spirit enemies which spawn in fixed locations. Each time a Cave spirit is defeated, a section of the hexagram will light up. When all the Cave Spirits are defeated, a treasure chest will spawn in the middle of the hexagram containing three Blessing of the Spirits items. Opening this chest will warp the player out of the catacombs and back into the camp, and this is the only way to exit the catacombs.

Trivia

 * If the player has entered the bonus code, the music that plays during the Catacombs will not appear on the playlist.
