NeoForgeClient and serverMIT LicenseOpen source1.21 – 1.21.5

What it does

The add-on adds two swords, two glaives and two scythes that use the Big Swords R weapon system, so they can be crafted and used alongside the existing Big Swords R weapons. Four new shields are also included, each carrying its own perks and weaknesses, which change how a player blocks and fights.

Big Swords R and Cosmicore are both required and must be installed next to this mod on NeoForge. The add-on runs on client and server, so both the server and every player need it. Files are published for NeoForge across four release versions, 1.21 – 1.21.5, and the latest file is 1.0.1 for 1.21.5, released 2025-04-13 under the MIT License, which makes the code open source.
