Using four pieces of Quadruple-Compressed Cobblestone to make a Compressed Cobble Crossbow Limb results in an absurdly, ridiculously, undoubtedly broken Crossbow:
With no level ups, that's 150 Hearts of damage, and an Arrow Speed of 75---nearly ten times faster than any other material. It can one-shot anything, at any distance, instantly (the bolt has no travel time), with pinpoint accuracy... and then reloads in less than two seconds.
It's a lot of fun. I call it the Finger of God. But I'm assuming this is unintended?
I realized that, when he added those parts manually he couldnt specify these abilities i guess, dirt crossbow limb has that as well. i used it a little bit but mining age was like a hell got rid of it since i have an awesome scythe now ( thanks to 30 creative golden heads from a legendary bag )
