I just wanted try out whether modding of the game xml files was workable, so i made two tiny -- sort of useful -- mods.
First a mod to craft a Glass Flagon from mana and Crystals.
Glass Flagon

The second one a mod to craft Radiant Gems from mana and Clouded Gems.
Radiant Amethyst

Radiant Diamond

Radiant Emerald

Radiant Ruby

Radiant Topaz

How to install.
There is a Mods sub directory located under the "Steam\steamapps\common\Sorcerer King", but this one seem to be filled with stuff from elemental. Therefor for now i have found the better solution is not to enable mods in the game, but to place the files directly in the xml directory. And that is rather simple, unzip the files in the "Steam\steamapps\common\Sorcerer King\data\English" directory.
Start a new game, and they should start to show up.
Enjoy.
