Tutorials/Ultra hardcore survival

If you have played Hardcore mode many times and are comfortable with it, and want an even bigger challenge, try Ultra Hardcore Mode. Ultra Hardcore mode is like Hardcore, but to add to the challenges of hardcore, you don't naturally regenerate health. This difficulty is extreme, so it is advised to try hardcore mode first to gain extensive experience, and move on to this difficulty when you think you are ready.

All the rules of regular Hardcore still apply, so read them first.

Creating a UHC World
To play on Ultra Hardcore, you must first create a Hardcore world. There is two ways to make a Hardcore world a UHC world. For the first method, once the world has finished generating, open the pause menu, click the open to LAN option, and turn on the allow Cheats option, before clicking the "Start LAN World" button. Once this is done, exit the menu and enter the following command into the chatbox:. Once you have completed these steps, save and exit to the title screen, before returning to the game. For the second method, click create new world or above, and set gamemode to Hardcore. Next, click game rules, and select natural regeneration to make it false. Once you have done that, click create world. Now you have successfully created your own Ultra Hardcore world.

Notes and Tips
Ultra Hardcore Mode, like mentioned earlier, is very difficult to survive when playing, and if you die, your map will only be available for spectating. Therefore, it's important to know how to avoid dying. Here are some tips:
 * First of all, as stated before, there is no natural health regeneration. So, remember to avoid even the most pathetic ways of getting damaged, such as being spat on by a llama or touching cacti.
 * You'll have to be really quick with getting resources, because no regeneration makes taking damage much more dangerous.
 * Find ingredients to make a golden apple, a potion of Healing, suspicious stew with regeneration, or a potion of Regeneration as quick as possible, as these are some of the few ways to regenerate health in UHC.
 * Although hard and labor-intensive to acquire, a beacon can make your life significantly easier, along with reducing the amounts of potions and apples you may consume.
 * Remember hunger is the most crucial part of survival. As with a normal survival, get food quickly. Hunger is a pitiful excuse for taking damage.
 * Keep a water bucket on your hotbar at all times. Falling and fire damage can be reduced by using a water bucket.

Tips that apply to PvP

 * A great way to check out if there are any players in the vicinity is to trap yourself in a small capsule. The lack of lighting causes everything to be dark except for name tags, which are now more visible than regularly.
 * Gold and apples are going to be your top priorities. Apples can be found on the surface and dropped from oak leaves, like saplings. In many cases you'll have more apples than gold.
 * While waiting for your items to smelt, consider farming Gravel to gain enough Flint to craft Arrows.
 * With the addition of Suspicious Stews to Minecraft, regeneration is much easier to get. Considering how mushroom biomes remain one of the safest environments, and the ease of growing flowers, Suspicious Stews may serve as an excellent early game healing item, and a much cheaper alternative to potions, albeit not nearly as effective.
 * Consider checking out YouTubers or Twitch streamers to see their UHC strategies.
 * The game usually goes up to 1-2 hours, so make sure you won't starve (in real life) or go to restroom, keep some water beside you and snack if necessary.
 * Check the rules before going into a game of UHC, some may have player head apple and strength/regen disabled, you might just want to read it before joining.
 * Strength is extremely beneficial (if not disabled), being able to deal an extra 3 damage $$, and 130% more damage $$ on only the first tier. Speed is another potion that is handy, being able to go 20% or 40% faster.

Beginning
There are a lot of options of what you can do play singleplayer UHC, but if you want to survive, you generally want to either not take much damage, or get a lot of materials to heal with. Generally you want to start by getting some wood and stone tools like usual. It's recommended to get a full set of iron armor before doing anything else, although if you are good at avoiding damage, this may not be necessary. It is also generally good to look for chickens for feathers before you start making skeleton grinders, as feathers are required to make arrows. Also it might be worth it to try to get apples (to craft golden apples), or leather and sugarcane (for making enchantments). This is probably a good time at which to hunt spiders for string if you want, although remember you can also get bows from skeletons and in caves. After you've gathered basic materials, you should probably either continue caving or go to the Nether.

Healing

 * Until you acquire a source of healing, all damage is permanent and unrecoverable.
 * Up until the Village and Pillage Update, the primary source of healing was potions of regeneration and instant healing. This would require you to visit the nether, find a fortress to obtain blaze rods and nether wart, and obtain either ghast tears or glistering melons, all without taking more than 19 points of damage.
 * After the addition of suspicious stew however, crafting suspicious stew with an oxeye daisy results in obtaining the regeneration effect for 8 seconds (6 seconds Bedrock Edition), and allowing for you to heal prior to visiting a nether fortress.
 * Boxing yourself in and sprinting and jumping to remove saturation and allow the decay of hunger is a valuable strategy to heal, particularly after fighting difficult mobs such as blazes or skeletons
 * As such it is advisable to seek out a plains biome for daisies, and carry around several bowls, both types of mushrooms, and oxeye daisies in order to heal when necessary.

Caving
Caving in UHC mode is what you make it. Generally people either try to go super fast or super slow. The goal of going super fast is to beat mob spawns through the caves and gain materials more efficiently. You can light behind you with torches if you want, especially if you plan to go back out the way you entered. If you run through placing torches you might want to not even mine ores to get through faster. The other approach is to go through caves very slowly. A lot of people will recommend this, although for competitive or time based environments, it's generally more efficient to just run through. When caving slowly, always block off mobs and attack their feet.

The Nether
Read the Nether survival guide first.


 * Lava is way too easy to fall into, and with no regeneration, you will die quickly.
 * If you are not looking, you can walk directly into fire, which never burns out on netherrack.
 * As fire damage can easily be a death sentence be sure to take a cauldron and a couple buckets of water with you, you can extinguish yourself by jumping into a cauldron filled with water.
 * Be watchful for sharp drops, and never dig down. Many floors are only one block thick, with the sea of lava directly underneath.
 * Ghasts can quickly kill you, as well as blow out your portal. Surround your portal with cobblestone, and listen for their noises. It is easier to play with subtitles on.
 * In a pinch, smelt netherrack into nether brick. It will not be destroyed by ghast fireballs.
 * Remember, on your first visit your highest priority is gathering a single piece of Nether Wart (maybe some Soul Sand to farm on) and at least two Blaze Rods. Opening up brewing makes future trips much safer with the likes of Fire Resist/Health potions.

The End

 * Bring a sword, preferably diamond.
 * Enchant your sword, bow, and armor(preferably diamond). Armor is especially important; go for Protection IV.
 * Always use arrows or other projectiles to destroy end crystals, rather than melee weapons. Two of the End Crystals will always be enclosed by iron bars, but this can be bypassed by getting close to their towers and shooting them from the opening at the bottom of the iron bars.
 * Players can spawn on an obsidian platform which floats above the void. This leaves players very vulnerable to being knocked into the void by the ender dragon. To reduce this risk, keep an ender pearl on your hotbar while entering the End, so that you can teleport off the platform. Remember though that when you do this you will also take ender pearl damage.
 * Throwing an ender pearl and then eating a golden apple afterwards will negate all damage given, plus give 2 extra hearts.
 * If you're prone to aggravating endermen, wear a carved pumpkin on your head. This will narrow your vision however, so be mindful of where you're walking. Pressing F1 while wearing the pumpkin as a helmet hides the pumpkin face, but will also hide your hotbar, health bar, and hunger bar. Alternative resource packs can make the pumpkin face texture transparent.
 * Keep a water bucket on you, as the ender dragon can fling you away and the fall damage will almost certainly kill you, so you can place it just before landing.
