Ever want to kill the wither, but you don't wanna lose your stuff &/or let him roam the world? well this is NO MORE with my simple Wither Room Design HAS TO BE A WARDED MATERIAL! You Just have to make a 7x7x7square making it 5x5x5 on the inside with a Warded material. & 1 block slot to attack it through. & KABLAM! 100% certainty that the Wither will not kill you. (Unless YO A NOOB) But yea. try it out yourself! you won't be disappointed. P.S: I know this is Noobish but I just want people to know a really efficient way to kill the Wither for all their Nether Star needs!
