What it does

The weapons include a Justice axe, a Justice spear, a Justice hammer, a Jevil scythe, a Black knife, a JARONA sword, a Lancer bike and a Real knife. The Justice axe is crafted by brewing an iron axe with a moss block. Most hostile mobs drop the weapons' materials, and a Shadow crystal crafting material is also added for building the rest of the set. The mod is built for NeoForge and runs on client and server, so the server and every player need it. It is published for 1.21.1 only, with the 1.1.0 file as the latest build.
