Tranquility seems to be failing to award experience properly. It's listed as warding/augmentation, but casting it with as much mana as I can muster doesn't move my Augmentation at all and Warding only goes up by one mind state. In contrast, most spells cast about as high as I can manage award about 4 mind states worth of experience. Awaken, which is warding/utility, seemed to split it up evenly so that I gained 2 mind states in both warding and utility. I would expect Tranquility to do the same thing as Awaken.
