First it tried to shoot wither heads at me and then it started flying around the nether I used my crafting table got my diamonds and made a diamond store to attack it. The wither was still shooting at me but I used my sword to push the heads back to hit him.I dealed some damage to him but he still had lots of health left on him so I used my bow to quickly shoot straight at him and jumping stabbing its bones straight through dealing a lot of damage. It went down to half health and 3 wither skeletons spawned and gave me the wither effect on me so I broke their bones in half to kill them. The wither was more angry and rapidly started shooting me with wither I so I shot him with my arrows from my from my bow rapidly to. I was nearly dead with 10 inches of health left so I stabbed him 5 times and he died. The wither dropped a nether star so I found my portal jumped back into it and back into the overworld. It was night and an Enderman was standing right next to the portal I stabbed it straight through its body and grabbed its enderpearl jumped back into the portal and killed some blazes to craft an eye of ender. I jumped into the portal and crafted it through it and a stronghold was under me so I dug down into it put the eyes of ender in and said "before I go in this could be the end of me" and then jumped on in
