Had a close call during training today. Was testing a new application of Quicksilver with Fusion Magic and... well, let's just say the south training field now has a very interesting new glass-like crater. Professor Vance was not amused. Spent the rest of the afternoon repairing it. It's a humbling reminder that no matter how much power you think you control, there's always more to learn. The real magic isn't in the destructive force, but in the precision and control. Back to the fundamentals for me tomorrow. Anyone have any recommendations for advanced control exercises?
