The Nether, also referred to as "The Nexus" in Notch's and Jeb's Blog on Tumblr, sometimes called "Gate to Inferno Fields" and was previously known as Hell and The Slip, is part of the Minecraft Halloween Update. It exists in a completely different world from the Overworld. The terrain is dimly lit, full of Lava streams flowing from the ceiling, sudden cliffs, and lava lakes, making it extremely dangerous to explore. The ceiling and the base of the Nether are made of Bedrock. Mushrooms are also commonly found. If the player dies in The Nether, they will be transported back to the spawn point in the Overworld, while your items stay in the nether for the normal amount of time.Maps can be made of the Nether, but they can only be created while there. If a player brings a map of the Overworld into the Nether it will stay the same but the marker that represents the player will be absent. Also, sudden bridges and shafts can be found through out the randomly generated world. You will most likely find the bridge partially destroyed, and the shaft is located near lots of enemies, so watch out. Always carry weapons and bridge repair kits, and useful renewable items with you. Sometimes, the Nether can be classified as useful or exciting, since you can find large quantities of Soul Sand and Glowstone, and you can grow Cacti there.
The portals are made by creating a 4x5 (2x3 on inside) door frame out of Obsidian and then lighting the inside of the frame on fire with Flint and Steel or a Fire Charge. The corners of the frame may be left out, using only 10 obsidian as opposed to the usual 14. When you stand inside the portal for the first time, it will create a portal in its equivalent area of The Nether. A loading screen will appear during the change of worlds.A portal can be shut down if part of the obsidian frame is removed (not including corners), or hit by a Ghast fireball.
When re-entering the Overworld, any distance covered in The Nether is multiplied by 8, effectively making The Nether a fast-travel zone that allows for greater distances to be covered in a short amount of time in the Overworld.
Walking through a portal will not teleport the player―in order to use them, the player has to stand still inside the purple haze. A recent update allowed Overworld mobs to go through portals and vice versa. Attempting to go through a portal while in a minecart or on a pig will result in the player needing to restart the game to continue - you can see permanent purple swirls. The same effects happen in the very buggy Far Lands.
A cool and useful way of getting spare obsidian is to create a Nether portal with the ordinary 14 blocks, travel to the Nether, remove the corner bits, then travel back to the Overworld and remove the corners there too.
Mobs and Enemies
Mobs that spawn in the main world do not appear here, except Zombie Pigmen which appear in the Overworld when Pigs are struck by lightning. Instead, there are special mobs that appear only in The Nether (although Ghasts have an extremely small chance of spawning through a portal on the surface world.)
- Ghasts ― Flying, jellyfish-like, 4-meter-cubed-sized monsters that shoot fireballs. They can be damaged by any conventional weapons, but they do not get hurt when on Fire, only when touching it. A Ghast can fly into lava falls or lava lakes, but even if they burn they don't get damaged (As of the November 10th Update). The fireballs they shoot can be deflected back at them using a fist or any tool by hitting it just before impact, killing it instantly if it hits (shooting an Arrow or using the Fishing Rod on the fireballs works too). They drop Gunpowder and Ghast Tears. Ghast fireballs cannot destroy Cobblestone. For this reason, many players like to use cobblestone as protection.
- Zombie Pigmen ― Docile (like wolves), humanoid creatures that turn hostile only when attacked. They now drop Rotten Flesh and Gold Nuggets and sometimes the Golden swords and a Cooked Porkchop when killed. A rare drop is a Gold Ingot. It is possible to obtain an Enchanted Gold Sword from them, but it is an extremely rare drop. They wield Gold Swords, and cause 2.5 damage. Attacking one causes all nearby Zombie Pigmen to attack you too, also like Overworld´s Wolves. Immune to both Fire and Lava.
- Blaze ― A hostile flying mob that appears in Nether Fortresses. They shoot 3 fireballs like a Ghast, although they do not cause explosions on impact. They drop Blaze Rods. Blazes cannot shoot when their Fires are out, they can re-light their Fire eventually or instantly if they touch Fire or Lava.
- Magma Cube ― The nether's equivalent of a Slime. When Magma Cubes jump they will show their layers. They can also set the player on Fire. Immune to both Fire and Lava. When killed, they split into 1-4 smaller versions of themselves. They are commonly found in lava oceans due to their usual behaviour of hopping in a straight line until encountering the player.
- Wither Skeleton ― A hostile mob like the skeleton found in the overworld. These black skeletons are found on or around a Nether Fortress carrying stone swords. They drop coal, stone swords (not 100% of the time) and Wither Skeleton Heads (also not 100% of the time).
- Enderman -- A gentle mob unless looked at in a certain body part or attacked just like a wolf. They have the ability of teleportation, however, they cannot teleport out of a few places such as Minecarts. Sometimes, you will be able to trap an enderman by stacking a fence into a cage. Endermen are 3 blocks tall, so do not make your house 3 blocks or more tall.
Blocks can be brought to and from the Overworld. So far, there are seven block types only found in The Nether:
- Netherrack- This block burns infinitely, and is the main block type forming the Nether. Setting these on Fire while travelling in The Nether is a great way to save on Torches.
- Glowstone- A golden block that glows infinitely, commonly found as stalactites on the ceiling of the Nether. These can be used as a light source underwater in the Overworld, and the Glowstone Dust produced when it is mined is an ingredient in making Potions and Redstone Lamps.
- Soul Sand- A brown block. When walked on, it slows the movement speed of the player and mobs that walk across it, and makes them sink down a tiny bit. It can be used to create minecart-only passageways and docks, as well as one way doors. It's slowing effect is doubled if an Ice block is placed under it. Some sad-looking pixel-faces can be seen on this block.
- Nether Brick- A dark purple stone that superficially resembles bricks. Nether brick can be used to make Nether fence, and can be broken easily with a stone pickaxe. It can be found in the Nether, specifically in strongholds.
- Nether Brick Fence- A dark purple fence. It can be mined in Nether Fortresses, or can be created from six Nether brick pieces.
- Nether Brick Stairs- A dark purple stair. It can be mined in Nether Fortresses, or can be created from six Nether Bricks.
- Nether Quartz Ore- An Ore found in the Nether. It can be mined with an Iron Pickaxe. Instead of Stone, it is Netherack that the Nether Quart is in. You can use Nether Quart to craft Nether Quart Blocks, Redstone Comparator, and Daylight Sensor.
Water cannot be brought to The Nether and all water placed will evaporate immediately due to the extreme heat and will instead turn into steam. However, you will have no problem placing lava in the Nether and placing an ice block will have no effect. As of current updates you are no longer able to have ice melt into water, instead the block of ice leaves nothing behind upon breaking.
The Nether's name is derived from the English word "Ether", meaning "In the outer reaches of space or in the heavens", or "nowhere known" + an N. Nether could similarly be derived from a mythical location known as the "netherworld", usually depicted as a place where the wicked go when they decease.
- If a Bed is placed while in The Nether and is right-clicked on, it will explode with lethal force (unless the player has enough armor) and a huge blast radius.
- Due to how the building height limit of the game was changed to 256, and the top bedrock layer still spawns at 127, in Creative mode it is possible to get above the bedrock layer and build on top of the Nether.
- It is possible to bring water into the Nether by using Cauldrons, but it can only be used for potions. Using the water bucket anywhere else will cause the water to evaporate instantly, unless the WATER block is hacked in.
- Very rarely a giant mushroom will spawn in the Nether.
- Nether means bottom or lower and since it is like Hell and Hell is at the Bottom, Nether is at the Bottom.
- In the Normal world, went you mine straight down you will reach bedrock. In creative mode, you can break bedrock except for the bottom layer. In the Nether, if you dig straight up You will also reach thelayer of bedrock. It seems that one layer bedrock is the wall between the Normal world, and The Nether.
- If you go into the Nether before another player you will see the player flying for about 30 seconds
- It is actually possible to place water in the Nether on the Xbox 360 version. If you go into the Nether in Creative mode and place a block of Ice (recommended near fire or glowstone), the ice will melt, leaving a water source block. If the water is not spreading, place a block next to the source block (not on it). This is ideal for Blazeman and Zombie Pigman mob traps.
- Some people like to troll people by blocking their nether portal with bedrock/obsidian when they spawn to the Nether.
