Forging

Forging is the one tier 2 crafting skill in the Kilning branch. It allows to create metal tools and parts from processed materials. Also it is possible to smelt lumps, bars and ingots from ores. Level 30 of Kilning is required to learn this skill. To increase Forging past level 30, Kilning skill must be at level 60.

Requirements
Here is a list of items, tools, and devices that a character needs to have in order to use the skill's abilities

Items

 * Charcoal/Hardwood billet - used as a fuel by forging devices

Forge Tools

 * Primitive hammer - used to craft the Blacksmith's hammer
 * Blacksmith's hammer - primary equipment used to forge metal tools, weapons, and armors

Devices

 * Forge and anvil/Blacksmith's shop - devices required in order to forge metal tools, weapons, and armors

Procedure
You need a smelting tool equipped, such as a Primitive crucible and stick.


 * Place either Billets or Charcoal into a Furnace and light it.
 * For metal tools/weapons, after the furnace is lit, right-click the forge and go to Forge - Metal Tools/Weapons.
 * Add ore (lumps, bars or ingots) to the furnace.
 * Use the bellows to increase the temperature to 1,000 for gold, silver, and copper, 1,500 for iron or steel, and 2,000 for Vostaskus.
 * Maintain the temperature using Billets or Charcoal as the ore or metal begins to melt. The temperature will drop exactly 3 minutes into the process requiring the use of bellows.
 * Once the source items had heated fully, smelt them into the desired item.

Recipes
The skill gives the character the ability to forge metal tools and metal parts. A character can only forge items if equipped with a Blacksmith's hammer/Primitive hammer and using a forging device (such as Forge and anvil or Blacksmith's Shop), that is on which is fueled by charcoal or Hardwood billets.

Quality Caps
There are three possible limiters to the quality of an item produced with the Forging skill: skill level, material used, and a non-linear recipe function, which the next section is dedicated to.

The first limiter is Skill. You can never craft a Forging item with a quality higher than your Forging Skill Level.

The second limiter is on the type of material used. Crafting an item out of Iron or Steel will produce an item with a quality lower than predicted by the recipe. Items made with Iron will be at 60% of the predicted quality and Steel at 80%. Consequently, this means that Iron and Steel has upper quality limits of 60 and 80 respectively. Items made from Copper and Vostaskus Steel don't have a quality multiplier.

Non-linear Quality Function
Unlike most crafted items, the final quality for an item crafted with the Forging skill doesn't necessarily result in the quality as predicted by the recipe. There is a noticeable exponential function or modifier to the quality of produced items.



Items that have a predicted recipe quality between 5 and 64 turnout to have a lower quality and items with a predicted quality of 66 and higher turnout with a higher quality.

The estimated equation for determining the final quality is as follows.

nl_quality = 3 + ( predicted_recipe_quality ^ 1.35 ) / 4.5

Eg, an item predicted to have a quality of 40 from the recipe, would turnout to have a quality of 35.

Keep in mind, this is just an estimate equation derived from experimentation and not an equation found in the game files.

Complete Formula
Combining this with the Quality Caps mentioned above, the following, and more holistic, equation can be used to determine an item quality.

nl_quality = 3 + ( predicted_recipe_quality ^ 1.35 ) / 4.5 real_quality_result = floor( min( skill_level, ( min( nl_quality * shop_bonus, 100) * material_modifier )))

The "material_modifier" is 0.6 for Iron, 0.8 for Steel, and 1 for Copper and Vostaskus Steel.

The "shop_bonus" is the bonus to quality from using the Blacksmith's shop; the "shop_bonus" is 1.2 when using a Blacksmith's shop. If using a Forge and anvil, the "shop_bonus" is 1.

These observations also apply to crafting armor components in the Armorsmithing skill.

 * Smelting Lump of iron and creating nails is the fastest way to level Forging. Nails may be recycled in multiples of 10 to return material. Alternatively, one may craft Throwing Knifes, as they are more effective in cost.
