"I wonder why the prices of these potions vary so much," Zeikin frowned, staring at the shelf of stat-boosting drinks. "Let's say a strength potion might be in demand among peasants, workers, loaders, and other laborers. An affordable price increases the appeal of this performance-enhancing drug for performing laborious tasks, and the final profit from the number sold will noticeably exceed the benefit lost by lowering the price. But who and for what purpose in everyday life would need a potion of evasion? It's unclear.
