Lock & Block Security
Adds fun and creative security features to protect your stuff
Quick answer
Which Lock & Block Security release should I use?
Lock & Block Security 0.10.2+1.21.1 targets 1.21.1 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. All 3 required mods have matching files.
Where it goes
Is Lock & Block Security required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Lock & Block Security 0.10.2+1.21.1 need?
0.10.2+1.21.1. Change the file and its required mods may change too.
Install Lavender, oωo (owo-lib), Fabric API 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.
