Darius was largely unimpressed by the display here and decided to move on. He went through stall after stall looking for something unique and rare, but ended up drawing a blank each time.
In truth, there were some special items that would have been treated as trading trump cards by him in the past. However, their value to the current him was not that great.
There wasn't anything there that couldn't be created through a small investment of CP and at a higher quality to boot.
Still, Darius ended up doubling back and buying them anyway. Why? Because he had the money, he had the space and he had the time.
Even if they were useless now, they could prove to have some use later. What made him change his mind was him noticing his growing complacency.
It was not too hard to notice. Darius was a calm person, yes, but he was also very cautious and very patient. He hadn't lost much of his patience or calm, but his caution had diminished greatly.
