Deltarune Weapons
by gallade_mega
Deltarune Weapons adds two weapons themed on the Deltarune game to Fabric builds for Minecraft 1.21.8, the Black Shard and the Devil's Knife.
What it does
The Black Shard is crafted from a Nether Star, Tinted Glass and other materials, and it swings extremely fast and hits hard. The Devil's Knife is crafted from Diamond, Gold, Amethyst and Netherite, and it is stronger than a Netherite Sword but slower. Both are meant to stay consistent with the material logic of the game they come from.
The mod is a Fabric build for 1.21.8 only, so it does not cover earlier or later versions. It runs on the client and the server, which means both sides need to install it. The code is released under All rights reserved, and the mod is not open source. The first release, 1.0, was published on 2026-02-22 and has not been updated since.
