#1) The first Charm is in the water lock in the beginning. As you're climbing up it, you'll pass through two spinning gears and go down a corridor with tiny openings. Go out one of the openings and Blink to the other side of the area. Go into one of the openings and you'll find the Charm next to a corpse.
#2) This one is inside of the tower, on the second floor. There is a hallway with a bunch of green tapestries and rugs, and in the one corner is a fireplace that is not in use. Besides this fireplace, on the wall, is a light that you can turn, which opens up a secret room behind the fireplace. The Charm is on top of the cabinet in this secret chamber.
