This addon allows you to create bedrock and bedrock weapons. To craft these items you will need a lot of cobblestone. You will have to compress thousands of cobblestone in order to get bedrock items.

you need to compress cobblestone 5 times to get the bedrockium, 6 times if you want the bedrock block.
bedrockium needs 59,049, making the bedrock sword need 118,098 bedrockium
a single bedrock block needs 531,441 cobblestone pieces, which is absurdly expensive without adding other mods.
