There were few limitations when it came to the techniques which could be used to create a Tideflow. In all the years which had passed since ancient times, only three rules had come to be identified in that regard. The first rule was that the techniques used for the Tideflow had to be completely mastered down to the tiniest detail. Without that level of success, the Tideflow would be a failure.
It wasn’t easy to master a technique to that level; it required a significant expenditure of both physical resources and mental energy.
The second rule was that with every Tideflow, only one technique of any given level of power could be used effectively. Adding in extra techniques would not help successfully achieve the Tideflow.
The third rule was that each successive Tideflow was more difficult, and the requirements for success were thus more stringent.
In most sects, there were few techniques that could propel a disciple past the fifth Tideflow and into the sixth. Such techniques were essentially secret magics, and the foundation of the true power of the sect.
