Sandbox games combine elements from different genres. They give the player complete freedom of action up to building a home and killing bosses. Most of the actions require some kind of resources that the player obtains in the process of exploring the world. In projects like Terraria, one of the key activities is finding and mining ore. This search is complicated by the fact that monsters and other inhabitants of the underworld will attack the researcher. Often the player has to run a hair's breadth from death in order to extract the desired ore for their own needs. Ore and rare stones are commonly used to create weapons and armor that are essential for survival.
The appearance of orichalcum ore
After defeating the Wall of Flesh boss, the world enters Hardmode. New monsters and bosses appear, new opportunities for crafting and construction open up, the game becomes much more difficult and interesting. Hardmode isa mandatory stage for the passage of Terraria (implies the killing of all bosses).
In order to stay alive at the initial stages of this mode, you need to tightly equip yourself with new armor. Depending on what kind of world you have - with distortion or with crimson, it is necessary to destroy the demonic or bloody altars that you have met more than once in hostile biomes. They are destroyed with the help of the "Bender" obtained from the Wall of Flesh.
It is enough to destroy three altars for all the necessary ores to appear in the game (type depends on distortion/crimzone):
- Destroying the first altar yields Cob alt/Palladium.
- Second Altar - Mithril/Orichalcum.
- Third altar - adamantite/titanium.

Searching for ore
Let's ask the question: "Where to look for orichalcum ore in "Terraria"? After the destruction of the second altar, new ores will be introduced into the earth. Accordingly, orichalcum will be in a world where there is a crimson. Orichalcum ore appears most often in the stone layer and below, not including hell. The ore is purple in color, so it can be easily distinguished from all other deposits. Unfortunately, the ore is affected by a tool with 110% mining power or better. Ore is mined with a palladium pickaxe or a drill.

What is it for?
Orichalcum ore is always smelted by players into ingots to craft armor, tools and weapons. Make an orichalcum anvil as the first item, as only on itit is possible to craft equipment from orichalcum. On the same anvil, items are created to summon mechanical bosses. The mithyl anvil can serve as an analogue of the anvil.
