Minor Update: Grammar and Magic

Nothing crazy here. Volume 2 saw some changes to grammar and fixes for other errors (no more 110% goblins), and I replaced a redundant section with running monsters, i.e., infravision (or really "blindsense" in this case)

Volume 1, begrudgingly, also received an update. I rewrote how Magic Users interface with arcane magic, and upped the healing capabilities of the party as a whole. Nothing too crazy, but enough to warrant an update sooner rather than later.
