About this mod Author’s original text

Lantern Keeper

This mod adds a new enemy that must be defeated using Chinese lanterns.

Lantern Keeper

Description

The Lantern Keeper is a dangerous enemy tied to a unique lantern mechanic

  • When he spawns, two lanterns appear along with him
  • He has 25 health points
  • Interacting with a lantern deals damage to him:
  • First lantern lit → -20 HP
  • Second lantern lit → kills him instantly
  • He can also be damaged through normal attacks
  • If a player starts interacting with a lantern and the Keeper is too far away, he will teleport closer and rush to defend it
  • Lighting a lantern takes 10 seconds, so players must find ways to distract or keep him at a distance

Combat

Description

  • The Lantern Keeper can throw a poisonous projectile.
  • If the projectile hits a player or an enemy directly, it explodes and applies the Poison status.
  • The projectile can bounce 0 to 2 times off walls or the ground, and explodes on its final bounce, releasing a cloud of smoke that inflicts Poison to players who touch it.
  • The projectile can also be reflected with a shovel if timed correctly. The reflected projectile can hit the Lantern Keeper.
  • Poison effects:
  • Can affect player and enemies.
  • Weakens the target, causing them to take 1.5× more damage from all sources.
  • Deals 10 damage over 10 seconds by default (increased to 15 total damage due to the vulnerability effect).
  • If the targeted player is poisoned, the Lantern Keeper will continue moving toward them and attempt a direct bite attack, which deals significantly higher damage.

Reward

Description

  • Upon defeat, the Poison Dagger drops
  • Functions like a regular knife but comes with the Poison Mark addon

Addon Ability (requires Addon Fusion to be installed)

  • Projects a ground marker following the player's aim
  • Reactivate to confirm the position
  • Applies Poison to targets in the area:
  • Deals damage over 10 seconds
  • Increases damage taken by 1.5×
  • Cooldown: 45 seconds
  • Can be transferred to any item using the Addon Capsule from the Addon Fusion mod

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:
