Block Strengthener/Tough Blocks
by nenuu91MOGS
Block Strengthener/Tough Blocks lets a player mark placed blocks as protected, so that only whitelisted players can break them with ordinary speed.
What it does
A new item called Block Strengthener is used with a right click on a block to make that block harder to break, with an effect equivalent to mining fatigue. Holding the item highlights protected blocks in different colors, depending on whom the protection applies to. Blocks protected from someone who is not whitelisted resist that player's breaking, while whitelisted players can still break them as usual.
The mod is aimed at survival multiplayer servers where owners want a way to guard a base without relying on claims or other protection systems. A whitelist is managed with a command, and operators have a separate prefixed command that lets them slow their own mining. Block Strengthener/Tough Blocks runs on Fabric and needs to be installed on both the client and the server for its features to work. Files cover 1.20.1 only, and the latest Fabric file is 1.1, published on 2026-04-17.
