About this mod Author’s original text

Deltarune Chapter 4 Darkworld

Deltarunes Dark Sanctuary, with all three regions represented. Explore the dark world for scrap and you may find something Titanic in the interiors depths, if you so choose to enable a certain setting in the config options. You may also run into something a little Scairy on the way.

This Interior also contains a few NPCs acting as room hazards, Others can be interacted with to start a Minigame. Survive, and obtain scrap pulled from the moons loot pool.

This Dungeon has pre-configured Weights for the following moons,

| Moon| Default Weight|

|:-: |:-: |

| Vanilla (LLL Tag) | 25 |

| Custom (LLL Tag) | 25 |

| Oneshot (LLL Tag) | 30 |

| Hometown | 300 |

| The Wild East | 200 |

You can change these settings in Lethal Level Loaders Configs by setting "Enable Content Configuration" to true, and manually changing the values to your liking.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
