A Dwarvish Anomaly
 

It is odd that if a Warrior gets both the Telescopic Sight and the Barrel of Dwarf Ale in the dwarf lands (which I did), and you marry Gerda because you want to see how an all- (or mostly-) Dwarf army will do, you can't "combine" those two items to get the special benefit because they are both artifacts and a warrior has only 1 artifact slot and Gerda has none. You would think that the clever Dwarves would make it possible to use the combination. Oh, well...

There is an workaround ....
Unzip the file in main folder\data\mods
Gerda's regalia,shield slot , changed to shield,artifact slot. For fun only.
