I got this PDF through DriveThru because I preordered. It is better than I imagined! A wonderful adventure about about an eccentric wizard and his experiments that got a little out of hand. 
Troika is very friendly to conversion so I plan to drop this wonderful horrible set of towers into any game I'm running. 

If you are looking for some deranged wizardry this book and the wizards of Slate and Chalcedony will add that Troika allure of weirdness in a heaping dose.
I do not think you'll be disappointed by Slate and Chalcedony.
