The content of the guide will be subject to change as the game updates.

• 2022 April 15 - Added some formulas from my own research.
  
• 2022 April 14 - Update, corrections regarding Iron, Copper, Tin and Soul. Added what Demonic should be in theory.
  
• 2022 April 7 - Creation.

• Impact : The amount of damage you do to the thing you hit. More Impact => Less hits => Less repairs => Less costs => More money gained
  
• Durability : The amount of damage your tool receives. More Durability => Less trips to the blacksmith => Less time spent on trips that produces no value => More money gained per time played.
  
• Gold and $ : The ingame money. Gold is either a material or the money in game but both "gold" are not related. So i'll use $ to mean in game money.

You might be aware that there is a problem regarding Demonite Ore.
I created 2 lines in the tables below to make the difference between what we should have Demonic (Theory) and what we have Demonic (Reality).

Basic informations about the ores :

• Ore : The name of the ore
  
• Smeltable : Indicates if the ore can be smelted in a furnace
  
• Hitpoints : How many damages you need to apply to break the ore completely.
  
• Durability : How many damages the pickaxe takes every time it hits the ore. The damage taken by the ore is the same whether you hit at 1% or 100%.
  
• Respawn time : How long you have to wait in seconds to see a node replenish.

Values regarding the ores, the process of smelting and the action of selling to the Shop Keeper :

• Ore : The name of the ore
  
• Price : (in $/ore) it's the value of a single ore.
  
• Price : (in $/ingot) it's the value of a single ingot. Doesn't apply to some ore that you cannot smelt (stone, coal, aluminite, bone and molten).
  
• Smelt time : (in seconds) is the amount of time required to create an ingot.
  
• Burns 1 coal : (in seconds) is rate at which the combustible is used

• Ore : The name of the ore
  
• Gold / Durability : The ratio of money gained for selling an ingot over the cost of durability of your pickaxe.
  
• Time for full stack smelt : (in seconds) is the amount of time the furnace will be busy.
  
• Gold per second of cook : In simple terms "How many $$ you earn per second if your furnace is kept busy 24/7.

Take the ore hitpoints, divide it by the number of hits you want to perform. You obtain the amount of impact needed if you hit perfect 100% (not taking account the critical bonus from a 100%).

Now divide this number by your average accuracy.

And you get the amount of impact you need on your pickaxe.

The formula is

I want to 3 hits soul ore !
Soul's hitpoints are 2160.
(2160 hitpoints) / (3 hits) = 720 hp / hits

Let's say i'm a pro and i hit on average 95%.

720/(95%) = 757.9 ≈ 760 impact

I then need to get my pickaxe's impact to 760 or above

I want to 1 hit topaz ore but i never do 100% and my average accuracy is 83% !
Topaz's HP = 1215
(1215 HP) / (1 hit) = 1215 hp/hit
1215/(83%) ≈ 1464 impact

Here are things you should know.

When you place a stack of ores in the furnace, you can immediatly add 4 more ores (or the amount needed to melt 1 ingot). This can make the furnace work for 1 minute longer for the case of Demonite/Soul ore.

You can move during the mining animation, right after the impact is done. This saves you a lot of milliseconds that adds up every time you grind.

To be continued.

Both ore are at the same tier.
Both requires 4 ore to make one ingot.
Usually the process of smelting ores to ingots adds a value of 2x to the price. (Because an ingot requires 4 ore but sells for 8x the price of one ore). For demonic ore the process of smelting adds 1.7x to the value.

Mining Demonic requires more effort than Soul, but rewards the same. Therefore Demonic < Soul if you intend to earn a lot of money fast.

The ratio of "Gold over Durability" is the same for most of the ores (except Demonic ore). It's 80. But to reach the same amount of gold earned, you'll need to spend more times harvesting lower ores. And this is not really worth it as your time is a limited resource.

If you want to create a tool, you'll need those formulas.

All values used in the game are not magical numbers. You'll see that they all depend from 1 thing that is:

• The tier of the ore.

What I call the tier of the ore is the natural order in which you obtain the ore. A tier can be assigned to several ore that share the same stats, but an ore can only have one unique tier.

There is no convention so I'll use my own. It starts from 1 and goes towards positive infinity.





Note : you can observe that the tier 3 has 2 ores associated with it.

If you like to start from 0 you can, but you'll have to update the next formulas by replacing the variable tier to (new_tier +1).


Integer Number

String

Boolean
There is no formula to obtain this one. You could find one, but you'd have to update it for every game update that adds ore.




I had fun searching this constant of value 840.
The correct formula might be 834/(tier-1). My measurements are not so precise. Disregard all i wrote about coal&time in this guide as it's not completely accurate.
