Some people asked for damage on the tools.
So if you let the plugin generate a new blocklist.yml (back-up before doing that) you well see a new option.
You can also add
tool-damage: amount to you currenct blocklist.yml, that should be working aswell.
Got any errors? please PM me. I do not visit spigotmc.org that much because I have a lot of exams (PM gives me an email)
In January I will have more time to spent on BlockRegen.
