Buy consumables here or go visit the market to buy equippable gear
A shady merchant approaches you and takes you by the hand. He shows you a hidden compartment underneath his counter. Your eyes widen. It is filled with rare consumables. You can't wait to spend your hard earned gold here.
The shady merchant sells consumables you can also receive by going out on adventures. It is for players that just don't get that one drop, are short of that one item or just can't be bothered grinding away.
