He had six potential points. In terms of secret techniques, the lower grade, middle grade and upper grade required 1 point, 2 points and 5 points respectively. The difference could increase the level of the secret techniques. Naturally, this was under the assumption that the user had the prerequisite needed to learn it.
After some consideration, Garen decided to learn the Ember Claw in hope that it would merge with the Red Jade Palm.
He finally understood that the merging of secret techniques was connected to his technique’s level.
This was the case for his Mammoth Secret Technique, as it acted as a foundation which most of his techniques were merged with and became an enhancement, as it had the highest level.
This meant that whichever technique had the higher level would become the foundation for the other techniques. Perhaps the grade of the techniques would affect it but it was not important.
He could learn two secret techniques up to the middle level with six points.
