Tutorials/Exploring an ancient city

Deep dark cities are one of the most challenging structures to defeat in the game. They are dark and are home to the warden, which can two hit you if you are wearing full netherite armour.

Reasons for defeating a deep dark city
There are several benefits of defeating a deep dark city:
 * To obtain sculk blocks, which are the only way to obtain them if you don't have a sculk catalyst already
 * To establish a deep dark city base
 * To get rare loot found nowhere else in the game
 * To obtain soul blocks and items without entering the Nether.

What You Need

 * Diamond Sword or Better (Fire Aspect II or better)
 * Golden Apples
 * 5-10 Milk Buckets (for curing Darkness)
 * Elytra (for quick escapes)
 * 1-3 stacks of Rockets
 * 3-4 stacks of Snowballs (for distractions)
 * Bed
 * Pickaxe
 * Food

Starting Out
To prepare yourself for an expedition to a Deep Dark City, there are a few things you need to do.

Finding the City
You first need to go to the deepslate layer, nearly to the bedrock level. If you mine into it from a higher level, there is more of a chance that you will mine into the city and die from fall damage. When you get to approximately level 20, begin strip or branch mining. This will give you the highest chance of finding a city.
