Install Draconic Evolution on your server

Draconic Evolution is an end-game tech mod by brandon3055. It adds high-tier tools and armour, high-tier RF energy storage, teleportation, mob farming, player detection and time and weather control. It needs two library mods, and players need all three in their own game.

Checked against Draconic Evolution 3.1.2.621 on Forge 1.20.1, October 2026. For NeoForge 1.21.1 the newest build is 3.1.4.633, which is a beta.

What it needs

Draconic Evolution runs on Forge and NeoForge. There is no Fabric build, and as a mod it can't run on Paper or Purpur. The 3.1.2.621 release covers Forge and NeoForge on 1.20.1 and needs Forge 47.1.96 or newer. NeoForge 1.20.4 has 3.1.3.622 as a release. NeoForge 1.21.1 has only beta and alpha builds, and it needs NeoForge 21.1.72 or newer. Minecraft 1.20.1 runs on Java 17 and 1.21.1 on Java 21, and the panel picks the right one for you.

Two library mods are required: Brandons Core and CodeChicken Lib. The 1.20.1 jar asks for CodeChicken Lib 4.4.0 or newer in the 4.x line and Brandons Core 3.2.1 or newer. The 1.21.1 jar asks for CodeChicken Lib 4.6.1 or newer.

Open Content in the panel menu and look for Mods. If the tab says Plugins or is missing, open JAR Manager under More, choose Forge under Server software, pick 1.20.1 as the Minecraft version and press Apply change. Leave Take a backup first ticked and confirm with Confirm & reinstall. Change your Minecraft version or mod loader has the full steps.

Install Draconic Evolution and its libraries

1. Open Mods, keep the Store view and the Modrinth chip selected in the source chip row at the top of the tab. The Game version filter starts on your server's version.
2. Search for Draconic Evolution and press Install on the result named exactly Draconic Evolution. Render Patcher and Update Spawner results are other mods.
3. A window titled "Needs 2 more add-ons" lists Brandons Core and CodeChicken Lib, which Modrinth marks as required. Press Install all.
4. Restart from the Console tab. The install message says "Restart the server to load them".

Open the Installed view to check. You should see all three mods and no Failed to load badge. A Needs badge names a library that is missing.

On a NeoForge 1.21.1 server the same steps install the beta build, because the store takes the newest release and falls back to the newest beta when there is no release.

Players need the same mods

Modrinth marks Draconic Evolution as required on both the client and the server. Each player installs Draconic Evolution, Brandons Core and CodeChicken Lib through their launcher, on the same loader and Minecraft version. Join a modded server from your launcher covers it, and Fix the mismatched mod channel list error explains the usual refusal when lists differ.

Settings

The mod's code in both the 1.20.1 and 1.21.1 jars points to config/brandon3055/DraconicEvolution.cfg as its settings file. Open it in File Manager after the first start. Its options include enableElytraFlight, enableCreativeFlight, armorSpeedLimit and disableLargeReactorBoom, plus enableGeneration in the Chaos Island category, which the code describes as allowing you to disable generation of chaos islands. Many values carry a comment, so read it before you change anything, and stop the server before you edit.

Common problems

• The server stops at startup: open Console and read the last lines, then look in the Installed view for a Needs badge. Fix mod and plugin errors on Minecraft covers reading the log.
• Draconic Evolution isn't in the results: it has builds for 1.20.1, 1.20.4, 1.21.1 and a few older versions. If your server runs another version, the results come back empty.
• Updating: click Check for updates in the Installed view and restart afterwards. Update the libraries along with the mod.
