Minecraft 1.18's increased height and limit for build has inspired many players to create many creations. Many of these creations don't even occur above-ground.
There are several things that players can do to increase their chances of survival, especially when it comes to Survival Mode.
These are most likely builds that one would make on the Overworld's surface. However, they require more effort underground as many materials aren’t readily available. This means that significant clearing of space is often required.
However, players can still create great survival builds and not have to worry about ever returning to the surface.
Direct sunlight is not required for farming because most Minecraft crops require light to stimulate growth. With this in mind, it's not impossible to build a farm underground.
Players can grow almost any crop as long as the farm is lit and has plenty of water.
Mining all the valuable ores and materials is one of the most important aspects of underground mining. Players can build a bigger mine with rail systems and furnaces and crafting tables to collect raw ore and process it without having to return to base.
This would allow players the ability to make and smelt what they need, before moving on to other tasks such as expanding their building projects or creating new tools. It is important to avoid running back and forth between the mine and player's underground homes.
Pickaxes are used to excavate the underground areas of Minecraft. This takes time, but also fills up inventories with materials like Cobblestone and Dirt, Andesite and Diorite.
It doesn't take much to fill up an inventory. Players should think about creating a well-organized storage area in the right circumstances.
You can also use this area to store ores, food, and other components. The storage area will work well as long as players know where they can find the items.
Even though players may not be exploring the Overworld biomes, that doesn't mean they aren't looking for a home. It is important to have a central location from which to craft, reach dimensions like Nether, or sleep when exploring the underground.
Low light levels make it easy for hostile mobs to spawn underground. This is why there is always danger. If players find themselves in trouble, they will appreciate having a central point to go to if they need to.
After they have refueled and recovered, and made the necessary items and gear, they can go back to work.
