So, i was in my survival world and had been going to the nether constantly to try to get wither skulls. after a couple of weeks I eventually got 3. so, I got some soul sand and got my full enchanted diamond armor, enchanted diamond sword, enchanted bow, 32 ender pearls, 3 enchanted golden apples (that's 24 gold blocks), and my lucky porkchop (from the first pig I ever killed in minecraft). I felt like I was forgetting something, but I just ignored it. so I summoned the wither and stepped back so I wouldn't be in the explosion radius. well, I wasn't far enough. the explosion hit me and destroyed much of he ground below me. well, apparently there was an enormous lava ocean right below where I was standing. What was I forgetting, you ask? Fire resistance potions. I lost all of the stuff I had. the worst part is that I had never eaten an enchanted golden apple before so I had no idea what it did. but now I know that it gives you fire resistance. And after that, I never played minecraft again. (until about the day after when I played minecraft again.)
