Elden Ring Item and Enemy Randomizer

It's an item and enemy randomizer for Elden Ring which modifies the files loaded on game startup.

Items found in the world, shops items, enemy and boss drops, and character starting loadouts are all randomized. Key item randomization is supported. Most enemies can be randomized as well, with extensive customization for different enemy types.

Normally, all you need to complete the game is two Great Runes and the Rold Medallion. The key item randomizer can chain key items together, especially when the bias slider is higher. There are also options to add, change, and remove key item requirements. In the most restrictive mode, you must collect all 7 Great Runes before you can challenge the final boss.

This mod is under development, and it will update when the game updates, so please check this mod page and the server for updates.

If you're a native speaker of languages supported by Elden Ring without existing mod translations or notice partially missing translations, you can add yourself to this spreadsheet and fill in the files in diste\Messages to help make this mod available in other languages. Also let me know if features are needed like font changes or space adjustments.

Installation

These instructions are a bit long, but mainly to account for all of the different ways you can use the randomizer with other mods and with different modding setups. For the simplest installation process, use Automatic Mod Engine. If you run into issues, check out the Troubleshooting section below.

There are mainly two types of Elden Ring mods: dll mods and file mods. dll mods hook into the game's memory while it's running, similar to what Cheat Engine scripts do. For example, Seamless Co-op or Item and Param Randomiser. File mods provide an altered version of the data files used by the game, such as regulation.bin (containing game params) or files packed inside archives like Data0.bdt. For example, this randomizer or Elden Ring Reforged.

File mods cannot hook into the game on their own, and require one of Mod Engine 2, me3, or Nuxe to do this for them. These tools are supported in the FromSoftware modding server ?ServerName? (https://discord.gg/mT2JJjx). Dll mods can be installed with something like Elden Mod Loader, or used standalone with their own launchers.

As a result, using this randomizer requires one of these three options (more details in Step 2):

1. Built-in Launcher (recommended). In this case, you can download the randomizer anywhere, and you do not have to download anything else. When you run the randomizer, it outputs hundreds of game files, and also outputs a config_eldenringrandomizer.toml file. You can click the "Launch Elden Ring" button in the randomizer to launch a built-in Mod Engine. Mod Engine may not work unless Steam is running, Elden Ring is installed in the default Steam library, and eldenring.exe has not been modified to run as administrator. To use additional dll mods, configure them with the "All dll mod" button in the randomizer.

2. Manual Mod Engine. In this case, you download standalone Mod Engine, and the randomizer is a subdirectory within Mod Engine. After running the randomizer program, you can use the Mod Engine launcher to launch the game. It will use those randomized files and automatically disable EAC, assuming all of the aforementioned Mod Engine requirements are met. To use additional dll mods, you must configure them yourself.

3. Nuxe. In this case, unpack the entire game from its archives (requiring ~50GB extra disk space) and then patch it to use the unpacked files. When you run the randomizer program in Nuxe mode, it replaces those unpacked game files with randomized versions. Then after disabling EAC, you can launch eldenring.exe (or any other launcher) and it will use the randomized files. This is not pre
