Choose two of the six attribute rewards. Su Xiao first chose Indestructible Constitution (exclusive reward). This ability's activation threshold rose from 25% of his health to 50%, a complete qualitative change.
This meant that once Su Xiao's health fell below 50%, he would enter his second-phase state. When it dropped below 20%, the blood-energy ability derivative "Death's Door" would activate, granting an extremely high melee damage bonus—in other words, he would enter his third phase.
Of the remaining five attribute rewards, Su Xiao chose "Master's Power (rare reward): Blade weapon slash-force judgment rank +5" without much hesitation. His previous battle against the Lady of Darkness had truly demonstrated the might of slash-force judgment rank.
Thus, with the bonus from Blade Master, "blade weapon damage rank" and "blade weapon slash-force judgment rank" reached parity at +24 each.
Once these two powerful traits were equal, Su Xiao sensed a wondrous balance in his swordsmanship. The former represented slashing lethality, while the latter represented slashing impact. With their values identical, they formed a perfectly balanced enhancement.
This made Su Xiao decide to develop both traits in the future and keep them as equal as possible. Even if their values could not be exactly the same, it would be best to keep the difference within two or three points, lest this wondrous and stable balance be broken.
It was worth mentioning that among the attribute rewards for breaking through 300 points in Strength, there were more "rare"-grade rewards than "ordinary"-grade ones. This was one of the benefits of undergoing the highest-difficulty trial.
If one underwent a regular-difficulty trial, obtaining a single "uncommon"-grade attribute reward from the six options would already be exceptionally lucky. Randomly obtaining a "rare"-grade reward would feel like winning the grand prize.
Your unenhanced True Agility Attribute has exceeded 300 points.
