Tutorials/Nether survival

The Nether is a dangerous hellscape filled with Zombie Pigmen, Ghasts (and in 1.9) Blazes.

Preparing For The Nether
The first step of preparing for the Nether is to make sure you have enough materials to build, or dig out, a small home within the Nether. Digging out a home is much easier than building one, Netherrack can be mined quickly with a stone pick, much faster than stone or cobble is mined.

You also want to bring a lot of Food - but not too much as dying in the Nether causes you to spawn back in the Overworld, and you will lose all your inventory items - and a full set of armour, preferably Iron. You will want at least a Stone Pickaxe/Shovel, or if you have loads of Iron to spare, use that. Swords aren't that useful in your first Nether visit. Most people won't attack Zombie Pigmen on their first visit, and you won't go searching for Nether Fortress's. So your only real enemy in your first visit will be Ghasts. Ghasts are one of the hardest mobs to fight in minecraft, mainly because of their floating ability and their fireball, which does considerable damage. Unless you're on a cliff and the Ghast is floating in front of you, the only way to take them out is with a bow and arrow. However, aiming and hitting a Ghast can sometimes be challenging. Once you have these tools, and enough arrows to take out a few Ghasts you will be ready to...

Enter The Nether
When you first enter the Nether, you may be awestruck by the amazing structure of it, however the Nether is a dangerous place, you will want to dig a small structure and out a Crafting Table and a Chest. Once you have set up your base to your liking, you will be ready to explore

Exploring The Nether
When exploring the Nether, there are a few things to remember,
 * Monsters can spawn anywhere there is space. No place is truly safe.
 * Compasses don't work, neither do maps, making navigation in the nether quite tricky. When exploring, try to keep going in one direction, and make sure you leave a trail of torches or dirt, something so you can find your way back.
 * If you encounter a blocked passage, a huge lava lake, or any other impassable obstacle, just follow your trail back to your base, and start off in another direction
 * Try to reinforce your base, if you attack a mob of Zombie Pigmen or have a Ghast on your trail, you don't want to run back to your base, only to realise that you don't have a door

When exploring the Nether it is a good idea to take some food with you, and to avoid sprinting, for two reasons in particular, if you run out of food, you better hope you can make it back to your base before you die, and sprint-jumping may send you straight into a lava pool. The only source of food in the Nether is Zombie Pigmen, and attacking one sends nearby ones into a rage, so make sure you can handle half a dozen at once.

Nether Fortresses
If you happen to stumble upon a Nether Fortress while exploring, it is a good idea to head back to your base, or even back to the Overworld, to get more supplies. You will want at least two full stacks of torches, an Iron Pickaxe and lots, and lots of food. There are a few things that are of the utmost importance when exploring a Nether Fortress
 * When exploring a Nether Fortress always place torches to your right, that way when you want to get out you just make sure that the torches are on your left.
 * If you find a Blaze Spawner, make sure you place a lot of torches, Blaze's spawn higher than level 6 light, so simply placing torches on the server won't stop them from spawning
 * If you come across a Netherwart plantation, collect as many (if not all) of them as you can, and then leave, follow your torches out, go back to your base, back to the Overworld and then store them somewhere safe. Netherwarts are an essential item in Brewing Potions, so you can't afford to lose them.

After you have secured the Netherwarts, explore the Nether Fortress thouroughly, you might not find much, but every once in a while there will be a Netherwart plantation, or a Blaze spawner, these are great finds. You might even encounter a Magma Cube, Magma Cream is another essential ingredient for brewing, for Potion of Fire Resistence
