    About

    Undead Expansion adds hostile creatures, loot-bearing locations, equipment, and a system for building and activating custom mob spawners. Its creatures include Revenants, which can stalk sleepless players as glowing eyes before becoming visible, fire-immune Demons in the Nether, and Haunters that can appear at night where a non-undead monster died. Wandering Knights and tougher Knight Leaders inhabit underground Lost Chambers, where spawners and chests offer further danger and loot. Graves generate in Plains, Savanna, and Forest biomes; searching them can yield ordinary loot, while night-time grave robbing can uncover rarer rewards and provoke a Haunter. Custom spawners are assembled with mob-specific Monster Ashes and spawner shards, then activated with Ectoplasm; Ashes can rarely drop from burned undead and spiders, while Haunters drop Ectoplasm. Notable equipment includes the Rotting Arm, a fast early weapon that can slow and nauseate foes; the Grave Scythe, which can make other regular mobs drop Ectoplasm; and armor sets with defensive effects tied to Revenants or Wandering Knights. Other additions include Rusty Tools found with skeletons and upgradable using iron, Demon-dropped Embers that burn longer than coal, and the High-Frequency Murasama Blade, which has an area attack when the off hand is empty.

    Written from CurseForge . How we write it

    In-game changes

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.16.5 to 1.18.2.

    Does not change the game's code directly.

    Adds 10 blocks, 42 items, 5 mobs, 36 recipes, 6 advancements, 7 loot tables and 1 sound.

    Counted from the names and data files in the mod, so the list may not be complete.

    Replaces 1 of vanilla Minecraft's loot tables.

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.16.5 to 1.18.2.

    We checked its files and read their code, without running it.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · Both latest files checked, last on 15 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      2 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.

    Privacy

    We found nothing it sends

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.16.5 to 1.18.2.

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Both files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of both files, for Minecraft 1.16.5 to 1.18.2. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files, images and sounds and found none.

    We have not read its changelogs yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
