I noticed that the help file on construct conveys the syntax for what you can construct and then conveys the syntax for each type. However, it appears as though it duplicated the syntax for armor and does not include the syntax for weapons. From my perspective this would seem to be an omission.
I apologize if this is in the wrong location, but I had trouble figuring out where errata or suggestions would go so I picked the closest thing I could determine. If someone can provide me with the location where similar issues should be raised I will make sure to submit it appropriately.
