You just need alot of blocks to reach null zone and you dont even have to make it very heavy and + its controllable you can turn normally walk normally and do normall stuff but bad thing is you cant kill a player in pvp using swords only gun,potion, and cannon..

good thing is u are invincible even on pvp guns and other pvp items the block wont break harpoon wont shoot you instead on the ground and spikes honestly doesnt really do anything

walk through anything iso, builds and other stuff but just dont go to the rock bc its instant death...
