This plugin implements custom mining tech into Minecraft. This allows you to customise breaking hardness for blocks by manipulating packets.
criticalmining.*: Gives all permissions under criticalmining
criticalmining.blockhardness: Gives the permission to use the blockhardness command
/blockhardness: Allows you to set or remove block hardness of a targeted block material, that being the block you are currently looking at (see https://minecraft.fandom.com/wiki/Breaking for info on what block hardness is). Block material is the type of block such as stone or oak logs. Structure: /blockhardness [set|remove] <blockhardness (this field is only needed if you selected set)>
