Through advanced schooling, book-learning, computer-enhanced skill programs, or just amazing intuitive perception, your hero has a talent for picking up skills on the fly. There is little he can't figure out given a little time and a dash of luck.

Any time he makes an unskilled roll for a Smarts-based skill, he may do so at d4 instead of the usual d4–2.
