This mod changes the wither, you will think a few times before attack him. If you want to meet him face to face then build the same sculpture as in the PC version of Minecraft. The new wither is indeed very large, in addition to this it has become stronger twice. You spend a lot of effort to win it especially in survival mode. The easiest way is to attack it using a bow, so you can protect yourself from the explosions. If you play the Minecraft Story Mode, be sure to remember this mob. Just think what it can do. That's what wrong with the world after his death, don't recommend you to spawn him close to your home. The boss now looks more scary and has new abilities. You can not defeat it using only a bow and arrow, you will need to join the melee. But the best way to defeat it is an attack with your friends. So, to spawn it you only need to build his sculpture, after this manipulations boss will be spawned, and you can try to win him, but it will be very difficult for you. If you will defeat it, it will give you a lot of interesting drop that you can use.
