Variable Spawner Hardness
by PaintNinja
Variable Spawner Hardness makes the time needed to break a monster spawner depend on the difficulty setting, so breaking one takes a little longer than in vanilla.
What it does
The mod changes how long a spawner takes to break. The hardness value is set per block and can be tuned in a config file named variablespawnerhardness-common.toml. Breaking a spawner with a tool is still quick enough to be practical, but bare hands are not enough to break one.
Its effect is a slight extra challenge rather than a major change to the game. Several blocks in the same family keep their vanilla hardness values, including end stone, ender chests, ancient debris and obsidian, so the spawner stands apart from them in how it is mined. Variable Spawner Hardness is server-side only, and it is released under the MIT License as open source, with source code and an issue tracker published. Files are published for Fabric, Forge and NeoForge across 31 release versions, 1.16.1 – 26.2, and snapshot builds are published as well.
Key features
Difficulty-based hardness
Spawner break time scales with the difficulty setting, adding a small amount of challenge to mining.
Configurable values
Spawner hardness can be adjusted in variablespawnerhardness-common.toml, so server owners choose the exact numbers.
Tool requirement
A tool is needed to break a spawner in a reasonable time, and bare hands do not work.
Vanilla hardness kept elsewhere
Nearby blocks such as obsidian and ancient debris keep their original hardness values.

What the author says
Makes spawners take longer to destroy depending on your difficulty for a slight extra challenge. Unlike some of the blocks mentioned above, you can still destroy a spawner with any tool you want as long as you don't use your bare hands.
