Sigil: City of Doors

so in the crafting wiki it says this:

"Crafted items can have up to 3 materials added to them (of different types). Investing extra rare or valuable materials in a crafted item will give it a higher enchantment point allotment. Adding metal to a predominantly wooden item will give it the DR piercing abilities of the metal added."

Ok, so... how does one know how many enchantment points extra an item is getting with other materials?  I couldn't figure it out when I was playing with the system today.

What were you trying to make?

I understand that either weapons or armor (I'm not in the headspace so I can't remember which off the top of my head) is currently bugged and doesn't gain the increased point allotment.  It should get 1 or 2 extra points depending on the material, however.

It's supposed to add +1 enchanting point to the maximum for using an expensive secondary/tertiary material. So a maximum of +2.

But right now I believe this only functions for quivers. Everything else, currently broken and using expensive material will just be a waste.
