Truly Modular: Arsenal
Truly Modular: Arsenal turns melee weapons into assembled items, letting players build swords and tools from interchangeable parts at a Modular Workbench.
What it does
Blades, guards, handles, pommels and tool modules can be combined into a weapon, and vanilla swords and tools can be modified this way within the Modular Workbench. The catalog set includes 12 blades, 4 guards, 6 handles, 3 pommels and 7 tool modules, with one double-sided module and cosmetic variants for some parts. Handles include a twin version for double blades.
Client and server both need the mod, since the parts are stored and recognized on each side. It is open source under the GNU General Public License v3.0 only. Required dependencies are Architectury API, Caelus API, Fabric API and Truly Modular: Modular Item API, and the Fabric API line applies to Fabric and Quilt only. Files cover 1.20 – 1.21.1 and are published for Fabric, Forge, NeoForge and Quilt. Truly Modular: Arsenal is required by the Epic Fight add-on Truly modular x Epic Fight (Unofficial).
