About this mod Author’s original text

Light Eater

The Light Eater is a roaming entity that feeds on energy, consuming light sources and plunging the environment into darkness.

Energy Seeking

Description

  • The Light Eater instinctively moves toward active light sources.
  • It absorbs energy from:
  • Dungeon Lights
  • Landmines
  • Turrets
  • Any grabbable object with an energy source
  • Energy-based enemy (Old Bird by default; new ones can be added via configs)
  • If an energy-based enemy is detected, it becomes the priority target (unless already chasing a player or absorbing a light).
  • Absorbed enemies are instantly killed.
  • After a configurable hour, it can target the ship, draining its power and disabling some functionalities.

Player Interaction

Description

Charged State

  • When sufficiently charged, the Light Eater can release a light detonation:
  • Players or enemies in direct line of sight are blinded.
  • They also receive the LIGHTNING status effect.
  • LIGHTNING status effect:
  • Can affect player and enemies.
  • Triggers an explosion halfway through the total duration and at the end:
  • Only affects players and enemies who are neither the target of the effect nor the one who cast it.
  • Deals 10 damage to nearby players and 1 damage to nearby enemies.
  • Applies the status effect to nearby players and enemies if they don't already have it.
  • Deals 10 damage over 10 seconds by default.

Low Charge Behavior

  • If not fully charged:
  • The Light Eater continues absorbing energy while chasing.
  • Any energy source crossed will be drained.

Countering the Light Eater

Description

Core Mechanic

  • The Light Eater is always vulnerable to damage
  • However, if it has any stored charge:
  • It will explode when hit.
  • All stored energy is lost.

Explosion Effects

  • Direct line of sight causes blindness to players or enemies.
  • If charge exceeds 100:
  • Applies LIGHTNING status effect in addition.

The Deluminator

Description

Defeating the Light Eater grants a unique item: The Deluminator.

Energy Absorption

  • Can absorb energy from:
  • Lights
  • Landmines
  • Turrets
  • Any grabbable object with an energy source
  • Energy-based enemies
  • Absorbing enemies:
  • Takes longer
  • Alerts them, causing them to attack

Charge System

  • Absorbed energy is converted into charges.
  • At 100 charges:
  • Can release a light detonation.
  • Causes blindness + LIGHTNING (line of sight) to players and enemies.

Restrictions

  • Can only be used during an active run (when the ship is landed).

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:
