The gosub thing as urban cowboy said. I saw a 22 and a 17 at one point.tHERE SEMS TO BE AN ISSUE WITH IT SELECTING (sorry caps) the Items that were made. Sometimes you get a quick glimpse of the fill gump other times it just stays on the screen and does nothing.

What does the script do when it finishes crafting the items and before combining?

It helps if you step through the code (F7) to see what it is trying to do to figure out any issue.

There is not a way to craft exactly the stats you need. Imbuing will allow you to pick and choose the resists but after imbuing it cannot be repaired at all. It has been a while but I believe that you want to use runic and make a bunch and then look at the pieces and pick and choose until you get the number you want with resists adding to the number you are looking for. You can also use reforging to help.

You can reforge items or imbue. There are some guides in here on both.

Geez I miss this one. Im playing on UO Forever now and trying to deal with Razor is a pain lol.. I miss the good old days!
