I GOT GREAT TIPS: 1.if in your house and there are hostile mobs outside use your line thingy and punch through blocks 2.if you die in acid your stuff will dissolve (like in lava) and water updates next to redstone so be carefull and press + plz and make sure you press + to hypnotic11 because its her/his idea!!!!
I couldn't fit it into the *next* update, but I'm thinking about 1.27 instead :)
