Weapon materials per pound and how to lower the costs

[Jackinthegreen]

I felt this was more a Min-Max type of deal, as far as saving money goes.  This might get a mini-handbook once more information is collected and condensed.

Let's say you want to make a weapon from a material that costs X gold per pound, such as Stormwrack's riverine 2,000 gp per pound.  If you make it for a standard medium-sized greatsword, that'd cost an extra 16,000 gp.  Make it for a small greatsword and it's only 8,000 gp. Then add the sizing enhancement from the MiC for 5,000 gp.  You just saved 3,000 gp or more!  The savings get much higher when we factor in size increases like Expansion, Giant Size, or even just Powerful Build or Strongarm Bracers.

Bastian + PLZ have the super Discount handbook guide

... so that covers almost all of the Magic + Crafting based stuff.
You're suggesting a new direction with Materials and Spells.
Interesting.
