There were audible gasps and heavy breaths taken. These people were truly cruel, using this auction as a springboard to decide the pricing of their items. However, considering the quality of the items in question and the undeniable demand, many nodded in agreement.
If the price was too low, just any dog and cat would be able to save up to buy it. That would be foolish, as even if they didn't know how such items were made, they could reason that supply would never be able to keep up with demand.
This was the truth as well. In fact, many powers here would be left speechless if they discovered that the items that had been brought forward in the last round had all been diluted/weakened.
The rule of thumb for Transmutation was that it enhanced an item by 5x its pinnacle quality. For those items to only be 200% better meant that Darius had cut corners in order to artificially increase supply.
