*The difficulty of building a MacGuffin
depends on its power. One to induce fear in Cybermen, operating
at Determination 6, would be Difficulty 6 plus a general modifier of 2 because
it attacks a specific immunity.
**MacGuffins are prepared for the right moment. The
time taken is until 1-12 research turns before they
are needed.
