Howdy! First of all, want to thank you for such an awesome game. Tis the eve of indie!
I know all Wiki's are to be read with a grain of salt, but found on the page "http://www.qcfdesign.com/wiki/DesktopDungeons/index.php?title=Gods#Taurog", it says that the glowing guardian rewards piety based on prior health spent, yet when I went to worship, I got zero piety. This has never happened on any of the other classes I've played.
My thoughts are that it's a bug with the way the transmuter gains health, but then again, it's a Wiki. Just wanted to put it out here.
Thanks again for the awesome game!
