Read the pattern and you'll learn what to do next. That was the gist of what the strange white-haired girl mentioned before she flew off.
Warden set aside his sword and sat down with his runic stylus. He didn't try to make the anti-gravity runes anymore; instead, he put his undivided attention into interpreting the wind pattern.
He let his awareness drift into the swift ambient wind and spent a good quarter of an hour entering the flow. Instantly, it appeared as if he had grown a third eye, as his awareness began to pick up on the intricacies of the pattern, linking with the ambient energy flow.
It wasn't the wind that created the pattern... No, it was the ambient energy all along. Warden just failed to see it until now. Warden could enter the flow state in two ways: once when he was wielding his spear to his greatest capabilities or when he got too invested in runesmithing.
