Enigmatica 2: Expert - Extended is unofficial continuation of Enigmatica 2: Expert

The aim of the addon is to make E2E even more interesting and challenging. Balance it out as much as possible, but leave the most interesting stuff untouched.



Here are +200 up-to-date 1.12.2 mods (about 400 total).
Despite this, the modpack only takes 30% longer to load than the original E2E. And the FPS in the game is even higher.

10+ additional major mods and +200 tweaking and Quality of Life addons. Some notable of them:

   New Content     QOL     Performance 

Thaumic Augmentation




Particle Culling


Construct's Armory


Traveler's Backpack








Thaumic Speedup




Hole Filler Mod




Tinkers' Evolution




Had Enough Items

Setup Guide

💥 Update your Java

To play this pack you must update your Java from verson 1.8.0_51 to newer one.
You can check out your current Java version in F3 menu or on 5th line of file logs/latest.log.

🪔 Install From Launcher

Just use New Instance feature of your launcher and choose "from CurseForge".
Prism Launcher example.

✊ Manual installation

  1. Download E2E-Extended_{version}.zip from Assets of latest release OR from CurseForge page.
  2. Use Import feature in your launcher.

🌌 Skyblock

In Skyblock mode, you cannot leave the starting Void dimension (with a couple of exceptions).
If you play on a server on which have already made these changes, the client does not need to change the configs.

In order to create a new Skyblock world, you need:

  1. In main menu go to Mods => Just Enough Dimensions Config => Generic => initialSpawnDimensionId set to 3
  2. Then Create New World => Create New World

Recommended mods

  • Entity Culling - increase performance, but can cause crashes on some machines
  • Dynamic Surroundings - better sounds and environmental, but increaing load time and lower FPS a bit
  • Fluidlogged API - adds basic fluidlogging, widely configured for E2E-E. Its not included by default since causing slight TPS consumption [1][2].



  • Prism Launcher E2E-E WindowWhere can I download the entire modpack with mods? You can't download the modpack in one archive. You can download everything except the mods, which are downloaded with the launcher.
  • Where is the server pack? You can find the server pack on the GitHub release page under the "Assets" tab or on the CurseForge file page under "Additional Files." Note that CurseForge may delay this file for download for approximately five days after release.
  • Prism Launcher E2E-E WindowI launched E2E-E and got a crash with Exit Code 1. Try loading the modpack a second time.
  • I loaded the modpack a second time, and it still crashes with Exit Code 1. Try using a non-CurseForge launcher.
  • I chose to download Optifine, but the Java process started, and the window won't appear. It seems like your firewall or proxy settings are not allowing you to download Optifine. Remove the file config/mod-director/optifine.url.json.
  • Outdated Java Version messageI updated Java, but it still shows me the "Outdated Java" warning. The CurseForge Launcher and Mojang Launcher use their built-in 8-year-old Java. To fix this, explicitly configure the path to your new javaw.exe in BOTH launchers, or use another launcher such as Prism.
  • I can't see crash logs. Crash logs are located in the folder crash-reports/. If there are no files, check the file logs/latest.log. If there is still no information about the crash, enable debug logging and the generation of the file debug.log in your launcher.
  • The game crashes on load, and the logs show something about Unexpected error and IllegalStateException: Already building! In any strange situation, remove VintageFix first.
  • What Java arguments should I use? I recommend using no arguments at all.
  • I installed the Essential Mod, and now I can't load the modpack. Remove the mod CensoredASM since those two mods are incompatible.
  • My world has 2 TPS, and it lags extremely hard. This happens when the OTG world rapidly generates new chunks. To fix this, pre-generate your world by pressing the "O" hotkey.
  • I'm getting 2 FPS, and I can't play. Remove the VintageFix mod.
  • There are too few hostile mobs at night. This is a known bug, and we are still looking for a solution.
  • Forge Mod Loader mod duplicates screenI updated the modpack version, and now it's reporting about mod duplicates. The best way to update the modpack is to create a new instance and move your world/configs into the new one. You may also want to move the following files:
    • options.txt for hotkeys and Minecraft configs.
    • hei_bookmarks.ini for item bookmarks.
    • XaeroWaypoints/ and XaeroWorldMap/ for map and waypoints.
    • config/xaero* for Xaero maps configs.
    • saves/ folders for worlds.
  • It's still reporting about duplicates. Remove .jar files without the -patched postfix.

Considerations Before Updating

Updates can bring exciting new features, but they also carry the risk of instability, such as crashes or loading issues. Despite thorough testing, unexpected problems can arise. If your current version of the modpack is stable and enjoyable, staying with it might be the best choice for uninterrupted gameplay.

Modpack Developing

This is unofficial addon and not supported by Enigmatica dev team.

Some of the changes from the Extended version [1][2][3] were added to the main modpack as well, so I became a contributor.
