There were over a hundred skills available, ranging from Rank 1 skills up to Rank 3 skills.
Lux didn't ignore the Rank 1 and 2 skills, and read all of their descriptions. For him, as long as the skill was useful to him, it didn't matter even if the skill had a lower rank. Since he had the ability, Skill Evolution [EX], he could easily get a stronger version of his chosen skill, once it was upgraded.
After pondering for several minutes, Lux was left with two choices which were the two passive skills Might over Magic and Warrior's Luck.
