Welcome to W.H.A.T. Professions?, the source book that lets you pick specialized Professional character kits for your W.H.A.T. characters. While the W.H.A.T.? game system is solely based on a customizable point based character generation and advancement engine, Professions allows characters to focus on advancing certain skills and attributes more quickly. A Professional Kit represents that the character is living a certain life style, or at the very least studying elements of that life style.
