How to create Cold Iron Longsword +1

I’m trying to make Cold Iron Longsword +1.

First I used vanilla Longsword with added Potency +1 rune but under Edit there is no option to add Precious Material Cold Iron.

Then I used Cold Iron Low Grade Weapon but there is no option of adding Versatile P trait, and I notice it puts it under Ranged.

Also I didn’t find out how to modify price of finalized weapon.

Please can someone point me how to properly modify weapon to add Precious Material and modify price properly.

Thanx in advance!

AFAIK, the only way to do that is to add a cold iron weapon (low, standard, or high grade), then modify all the statistics in the edit tab.

Note, for whatever wonderful reason, “cold iron weapon” does not show up in the “weapon” selection - you’ll have to select “all.”
