Hero's Lib heroslib-1.1.0.jar+1.21.1 targets 1.21.1 with NeoForge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 1 required mods have matching files.
Where it goes
Is Hero's Lib required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Hero's Lib heroslib-1.1.0.jar+1.21.1 need?
heroslib-1.1.0.jar+1.21.1. Change the file and its required mods may change too.
Install Cloth Config API (Fabric/Forge/NeoForge) first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
