I actually referred to Ralph earlier in the thread as a summoner/conjurer.... Of bullshit, but still.

He literally has to. A small backpack does not easily come on and off a man of that carriage. Ralph doesn't want a miniature, breath consuming battle every single time he needs something.
Anything in a fanny pack would be crushed and/or inaccessible unless he strapped it by his belly button (aka on top of his gunt) Good luck finding one with a 6 foot strap.
The purse is a necessity at this point. He can sling it at the smallest possible angle so he doesn't need an enormous strap, it doesn't inhibit movement like the other 2 and he has easy access to his things.
