[Shadow Stranger]

If you had the time and the interest in it, you could probably do it yourself. The key ingredients are a list of the items and a list of the dialog strings used for each store. I still only know about half of the stuff.

As far as I can tell, the Stone Blessing being required for enhancing an item's armor value is unfortunately correct. It might be a good idea to bring the Valkyrie into play earlier, around Shurugeon Castle, this makes it easier to draw up a party line-up. A Warlock can't buy levels in Stonecraft if he does not already have any. Among basic and elite roles, only a Wizard knows Stonecraft. Blessings are Priestly not Wizardly skills.

Found an interesting table in the record for Brimloch Roon Temple:
3 22 0 0 132 3 7 10 5 7 8 3
3 22 0 0 133 3 7 22 5 7 14 3
3 22 0 0 134 3 7 34 5 7 26 3
3 22 0 0 141 3 7 46 5 7 20 3
3 22 0 0 39 3 7 58 5 7 32 3
3 22 0 0 41 3 7 70 5 7 131 3
3 22 0 0 43 3 7 82 5 7 29 4
3 22 0 0 84 3 7 94 5 7 226 4
3 22 0 0 97 3 7 106 5 7 232 4
3 22 0 0 52 3 7 118 5 7 27 6
3 22 0 0 53 3 7 130 5 7 118 7
3 22 0 0 54 3 7 142 5 7 112 7
For the first seven columns, it has the same entries in all three temples. But then the Dojo has mostly different entries for the fifth column, so I figure this table varies with the type of shop.
