# Metallurgy

Metallurgy is a custom CW system that allows players to melt down unwanted metal items and then extract more rare materials from it. Metallurgy NPCs will also accept some non-metal items in exchange for some of the metal in their stockpile.

**Base Yield**

This is the minimum yield chance that the ore can have, assuming you have atleast hit the requisite 1% weight ratio.

For example: Tin Ore has a base yeild of 30%.

**ASSUME** the *weight ratio* for Tin Ore is 10 kg/1%.

**ASSUME** the player has 11 kg of weight stored up.

The player would have a 31% chance of getting a Tin Ore. 30% of the chance would come from the Base Yield and 1% would come from the Weight Ratio (10kg/1%).

**Weight Ratio**

This is simply how much weight is required to get an additional 1% increase in potential ore yield.

For example: If the player has 35kg weight and the Weight Ratio for a particular ore is 10kg/1%, they would have a 3% chance of yielding that ore (ignoring any Base Yield that may be present).

If the player has 216kg weight and the wight ratio for a particular ore is 21kg/1%, they would have a 10% chance of yielding that ore (ignoring any Base Yield that may be present).

**Yield Cap**

This is simply the maximum possible yield chance that a particular ore can have, regardless of stored metal weight.

**Extracted Metal Ore (Metallurgy)**
