Minecraft wiki entry for Nether_survival, associated text: Once you do find one, it is a good idea to make sure you have the necessary supplies to gather its many resources. So, head back to your base, or even back to the Overworld, and get, at a minimum, a stone pickaxe, an iron sword and lots and lots of food. An enchanted golden apple is handy when it's time to take on a blaze spawner, but you may want to stash that nearby and go back for it when you actually find the spawner. Trading with piglins can also get you potions of fire resistance before the fight. Lots of walls of any non-flammable material or nether brick fences are handy too: safety railings on the walkways are really nice when ghast starts taking potshots at you and blocking off unused areas and broken bridges helps cut down on fights.
