How can I still kill Wither in Minecraft Pocket / Bedrock edition NOT JAVA (!) except that I let them suffocate in obsidian or in bedrock / foundation stone?! (I don't want to do anything stupid that's why the question)
Make a closed cage out of obsidian (preferably with a space of 3x3x3 blocks) and shoot arrows from above through a hole.
He rises first and so he would keep shooting at me the whole time?!
Do it normally
Is somehow boring with na PERFECT netherite armor… And a sword that kills everything in a very short time?!
No, because the hole is too small. By hole I just mean a 1 block hole and not that you should leave the blanket off. So that the explosion doesn't hit you, you should also build a 2-3 block high platform on which you can stand.
