There used to be a plugin called Obsidian Destroyer but it is out of date and has not been updated. There are others out there like FatTNT (too complicated) and ObbyDestruct (no obsidian durability). Obsidian Destroyer worked really well and I am looking for something like it or someone who would update it. I am wanting to use it on a Factions server where people make bases out of obsidian and use TNT cannons to break through enemy bases. Thanks.
Not Official, The original dev is inactive but a few of us are keeping Obsidian Destroyer up to date "offline". https://github.com/squidicuzz/ObsidianDestroyer Recently I've worked with the developer of a cannons plugin, and we've added support for Cannons. I use both of these on my Factions server and they work great.
