I had one potion that I looted from the Love Dungeon which I had not managed to sell so far. I refused to sell below the average price because I knew that it was an important potion that could decide everything in a critical situation. In the end, I was grateful it didn't sell. Who would have thought that the Third Job Advancement Test would be so difficult?
I drank the Unseen Potion in one gulp. The potion granted me access to a rogue's precious skill, Invisibility. One could remain invisible for five whole minutes. The five precious minutes were all I had to beat the Evil Mantis Lord.
