Added option to toggle off hints/direction arrows for dice (h/t Kazanski's wife)
Increased volume of Wave Starting, Wave Warning and Final Wave sounds
Reduced volume of breath sound when casting spell
Reduced volume of attack error sound (e.g. trying to attack while still cooling down), since it can be annoying when spamming it. It is slightly louder when hitting an invalid hotkey, since you won't be looking at what you're selecting so aural feedback is more important there.
