Mystical skills are the most versatile skill set in the LoRD game. T and D skills have but one option for usage, but M skills present an ever-wider range of uses as you rack them up. As a result, they have the biggest potential benefit in any given day, and they're often underused by beginning players. Knowing the uses for each spell, and how they can be used in concert, can bring what looks like luck to your game, but it's actually pure skill.
