The walls of a lithomancer's apartment will be lined with old blue lines. There will be vellums and yellow trace all over things. Even when just going from place to place, a lithomancer will always have a sketchbook and pencil and will be drawing non-stop. Lithomancy is all about order. If it can be said that one form of magick is in direct opposition to another, then it would be said about chaos and drafting mages.
Lithomancers naturally divide and define everything.
Any good lithomancer will tell you he is meticulous. Any of his friends will tell you he is anal-retentive. Cuts tear across the person's chest. Skin gets evenly flayed off. Everything is nice and orderly.
