This file is a simple randomizer for game setup that includes both the Thunderstone base game and Wrath of the Elements, and also includes the Clan hero promos available at BGG and the Guardian promo from GenCon.
Use the standard F9 key to refresh and randomize again. I left all the working cells to the right unhidden in case anyone wants to see how to do a file like this of their own. I set this up so the randomization self-adjusts to choose the correct number of Dungeon Features and Monsters. Adjust the colors if you are able as the standard ones are poor for xls files.
