Minecraft wiki entry for Nether_survival, associated text: Find a nether fortress and break in. Use the right hand torch rule for exploring. Take the loot from the chests and try to find diamonds. Get nether wart and blaze powder. Make some ender chests and put your loot inside. Have some spare eyes of ender if you don't yet have silk touch. Avoid blaze spawners, as you don't have a lot of armor. Kill lone blazes and as many wither skeletons as possible. You need 3 wither skeleton skulls to spawn the Wither. There is no way to craft enchanting tables, so you can get Looting only through ruined portals. When fighting, make sure piglins, other skeletons, other blazes, and endermen cannot get to you when you are fighting.
