Timothy wasn’t going to buy a mana quality upgrade anytime soon. He couldn’t afford it, first of all, but that wasn’t the main reason behind his decision. He didn’t feel like spending them due to various reasons, so he’d rather accumulate any and all system points for now, and spend them later on, perhaps on more sensible purchases.
Since the quality of Tim’s mana was at level two now, he felt like his normal self again, he felt confident! He was powerful enough to do plenty of damage, independently, and that was the second, more important reason behind his prior decision. He didn’t feel the need to upgrade the quality of his mana again so quickly, he wasn’t in a rush.
Despite the main reason why they’ve entered this micro-universe to begin with, which was to improve the quality of the individual mana they bore, he wasn’t in a rush. Level two was plenty for a crafty rascal such as himself.
