UnderWaterTNT
UnderWaterTNT makes it possible to raid, the (almost) unraidable base. In some Minecraft version, it became impossible to blow up TNT underwater, although before it was possible. TNT cannons would however not blow up.
To mimic this experience in our servers, a plugin was written. UnderWaterTNT allows TNT to be blown up under water, to make water base- raiding a lot easier.
There is also a way to raid underwater bases with sand, however to prevent every base to become a water base, we added this plugin to make the raiding possible.
