Minecraft wiki entry for Multiplayer_PvP_bases, associated text: You will need a different set of supplies in your base if you're in the nether, you will need extra brewing stands for the constant resupply of fire resistance potions, fewer chests devoted to fuels since buckets of lava and blaze rods are readily available. Furnaces are also needed less in general as few things in the nether need to be smelted. Weapons and armor will see much use, so have extra anvils ready. A map showing where the nether portal is located is also crucial should you need to return to the overworld. Crafting tables remain necessary, as will enchantment tables. Setting up a melon farm is likely your best source of food, as the plant's growth is unaffected by how fertile the soil is. Be sure to have cauldrons filled with water. For defense, you can usually get away with pitfall traps and arrows, though you will still need obsidian padding.
