[edit ] Basic Information
Alteration is the school of magic that allows you to manipulate the physical world around you. From transmuting of mundane objects, to abilities like Stoneflesh that give you the bonus armour when you need it!
It's difficult to say what the most useful trait of alteration is. It can be used for everything from helping craft that new chest piece, to making sure you don't drown.
