Minecraft wiki entry for Nether_survival, associated text: Being well-equipped is essential for survival in the Nether. Lacking even a seemingly useless item in an unfortunate situation can put you in serious danger. However, be sure not to bring any items that have little or no use for your objective, leaving room to carry the loot you came to the Nether to find in the first place, as well as reduce the number of items lost if you die.
