When notifications appear for changes in Gold/Health/XP, there's a quantity represented by a "water drop" icon. I'm guessing it's supposed to be Mana--but that's odd, because Mana is represented on the stats readout as a lightning bolt. I'd advocate for using the lightning bolt in both places, or even better, a flame like the web site uses (for consistency).
