Created on e1.5.3. But I've try to reference to 1.5.2 and 1.5.4, it seems alright, but didn't tested on.

In a town where smithy workshop exists, there will be a new menu with the following menus inside :
- Forge Menu: You can buy random forged weapon (Just like player crafting, but all crafting parts are randomized)
There are 4 Tier for the forged weapon, basic, middle, high, master, and it will have different range for additional stat for each tier.
(Configurable: Purchase cost, Additional Stat Range, Added Stat Cap)

- Enhance Menu: You can enhance your equipped melee weapon only
You can enhance a weapon a limited times, and the enhancement will acuminate.
(Configurable: Enhance cost, Additional Stat Range, Added Stat Cap, Number of times of enhancement)

- Refine Menu: Refine the enhanced weapon (Delete the enhanced weapon from item list), get back a weapon with original stat
(Configurable: Refine cost)

This mod works with custom weapon. Also, if you uninstalled the mod, the enhanced weapon as well as those forged weapon will still be in your save.

Configuration:
- Various Forge Cost
- Enhancement Cost Multiplier:
Enhancement cost = Value of the item that needed to be enhanced * Enhancement Cost Multiplier
- Refine Cost Multiplier: 
Refine cost = Value of the item that needed to be refined * Refine Cost Multiplier
- Number of times of enhancement: 
You can only enhance a weapon for 5 times in default.
- Stat Range:
Just like normal player crafting, some random additional stat will be added to the weapon, this is the possible maximum per item of it.(Item = Swing Speed, Swing Damage, Thrust Speed, Thrust Damage, Handling)
For example:
If default is 5, swing speed may have chance to add additional point from 0 to 5, same as the other items.
- Stat Sum Cap:
The total additional point will be added to a weapon.
For example:
If default is 10, the maximum point will be added to five items would be 10, i.e. swing speed +3. damage + 3, thrust damage +4, other two + 0.

Mechanics:
Forge:

• Just like player crafting, but all crafting pieces are randomized, and no rename function.
  

Enhancement:

• Create a copy of the weapon, then override the stat of it, so you can see two version of the same weapon with different stat in cheat menu.
• If you want to re-enhance the enhanced weapon, it will remove the current one, then recreate a new one.
• Therefore, there will be not too many same weapon with different stat in the cheat menu.
  

Refine:

• Delete the enhanced version copy of the weapon
• Give the original version of the weapon back to player
• Enhanced version will not appear again in the cheat menu, unless you enhance it again.
