Todd was somewhat disappointed when he heard he could only buy ten potions.
If possible, he would have bought every potion here and taken them back to study at his leisure.
After some thought, Duke said, "I can sell you more potions as well, but you'll need to trade your potion formulas for them."
Although he still had quite a few potion formulas in mind, those potion formulas had not yet been leveled to the maximum and could provide him with free attribute points.
But once all those potions reached max level, Duke would have no more potion skills to grind for proficiency. So, he needed to start preparing early and ensure a stable source of free attribute points for some time to come.
Todd pondered for a moment. Potion formulas were not particularly important to him.
Potionists were scarce to begin with, and only potionists needed such things. They held little value for anyone else.
Since Duke needed potion formulas, it was naturally not because Todd's formulas were superior. He most likely wanted them for research and study.
Todd said, "All right. How about one extra potion for each potion formula?"
"Of course. A very fair trade," Duke said with a smile.
Todd could have chosen to have someone else buy them for him, but he could not bring himself to do that.
Besides, he feared that if Duke found out, he would cut off all exchange of potion-making knowledge with him. In the long run, he could not do such things behind Duke's back.
Since Duke had set the rule that only ten could be purchased, then he would follow Duke's rules. It was perfectly normal for capable people to have a few strange rules.
Moreover, potions of such high purity could not possibly exist in great quantities.
