Return to the Palace of Sakemoko
"Jin, I can in fact make Ales or Iskander -- or yourself -- a little faster for a long time. As long as I can stay awake, for two or three people. Maintaining too many spells makes it harder to cast new ones, however. If I were to make you, and Ales, and Iskander faster, I'd increase my risk of failing when I need to cast an actual combat spell -- indeed, greatly multiply the chance of the spell failing in some spectacular or even dangerous way.
"That was why I dismissed my lights at various times in the tunnels: because I needed to cast other spells, and didn't wish to risk failure unnecessarily.
"And no, I have no spells that I use in my personal life. Most spells you'd consider useful can only be learned if you already know certain other spells -- other than one or two in each college, known as 'basics', spells build on other spells. Levitation requires that one know apportation, which moves an object without the need to touch it. Flight depends on knowledge of levitation. Hawk flight, which is faster, builds on flight."
