Travis looked at his Skill tree and decided that was something he'd have to spend some extra time looking into. There wasn't a guide for his particular skill tree, mostly due to the fact that it was a very unique class. He's likely the only person who would ever have such a thing. Finding the right balance of Skills, buffs, and debuffs to use was going to take an extensive period of time he didn't have at the moment.
More importantly he was focused on the Primordial Skill Stones that he used. Averoth stated that there was no way to properly to tell what you'd get until after you use them. It was likely Travis just used several hundreds of millions of gold coins in his Skill Stone craze.
He was worried that he wasn't going to know what he obtained, until one name in his Skill list stood out from the others.
