Those ignorant of the subject abided by a simple equation. Rank 3 materials were beyond rooting experts, so only branching experts could interact with them.
Instead, masters knew exactly what the problem entailed, but their greater knowledge and expertise didn't make the two-faced hurdle any more complicated.
A rooting expert didn't have a strong enough Qi to refine rank 3 ingredients. Even if he did, his energy reserves couldn't last for an entire rank 3 concoction. It was truly that basic.
The inability to use elixirs and Qi-Storage pills to compensate for that gap was more complicated since it involved the split-second decisions a concoction's variables demanded. Still, no one had to go that far to label the practice impossible.
