Reynard's prediction about another hellish day was entirely correct. Frozen Balance's instructions didn't grow much clearer after the first one, and its teaching methods didn't become less potentially deadly. But after the first puzzle was beaten, Reynard and Marien understood much better what was expected of them, and stopped stumbling blindly.
The bird taught two magi the next refinement operations in its method. Each of them was somehow using ice or cold, and each of them required the bird's personal help in creating them.
It was no wonder that a second copy of Frozen Balance couldn't be made, and even its knowledge couldn't be transcribed. Even if Reynard wrote down everything he did, he wasn't sure it would work out for someone without the bird's magic.
