The first thing Izroth did when he entered into the auction house was access the Auction Cube linked to his character. When he viewed the total amount of coins he earned from selling the Five Cycles Pill, he was pleasantly surprised.
'The average price per pill is higher than I thought it would be.'
The average price listed per pill was 26 gold coins and 55 silver coins. Back when he first purchased the ingredients to craft the Five Cycles Pill, Izroth only spent 22 silver and 50 bronze coins. From a single pill alone Izroth had made more than ten times that of what he spent to craft 150 pills!
If the top guilds knew that Izroth was not using common ingredients and was left with such a massive profit margin, they would all be dumbfounded. One of the most important things for top guilds was a steady flow of income.
