Plugin to allow you to modify the explosion resistances of blocks. By doing this, you can make certain blocks more or less resistant to being broken by explosions. This may not work for all blocks, particularly some that are intended to be unbreakable by explosions.
This plugin in theory should work for any version on Paper or forks on versions 1.20.5+, provided they are using Mojang mappings (all Paper servers on those versions by default support this).
If you are using Purpur or a fork of it, Purpur already has config options to override the explosion resistance of blocks found here and that should be used instead.
