Deltarune mod
Deltarune mod is a Forge addition for Minecraft 1.20.1 that brings content from Toby Fox's Deltarune into the game, including dark world shops and Ralsei weapons.
What it does
The mod adds dark world shops where players can trade for items themed on the Deltarune setting. Ralsei weapons are part of the added equipment, so players gain new gear that fits the adventure side of the content.
Equipment is the primary category, with adventure, game mechanics and mobs as secondary categories. Both client and server need the mod, so the server and every player must run it. The latest Forge file is 1.1.0 for 1.20.1, published on 2025-05-16, and the first release came out on 2025-04-30.
The author credits MCreator for making the mod possible, and the notes state that Deltarune belongs to Toby Fox. The code is released under the CC0 1.0 Universal license, which is not open source, and the author says updates are made regularly.
