Tressa is a merchant who hails from Rippletide, a small seaside town in the Coastlands region. She works in her parents' shop, stocking the shelves, although she longs for journeying across the lands. Tressa is a natural born haggler and has a keen eye for determining the true value of something she sees, even for the first time. One of her faults is that she tends to trust people a little too easily.
Tressa's Path Action, Purchase, is similar to Therion's Steal, as it allows her to obtain items that NPCs have on them. However, she will need to pay money in order to get them. Consumables and pieces of equipment, if they're available in shops, tend to be cheaper when buying from NPCs. There is a slightly hidden function with Purchase, as sometimes Tressa will get a discount, although this tends to be completely random. You might find items that can only be Purchased, as well as some that cannot be bought.
Tressa's Talent, Eye for Money, is unique, as it will seemingly give you money for just exploring various places. What it really does is grant you some money for crossing into a new area, which is determined by a few different factors. The Danger Level of the area, in addition to the number of steps you take in an area before switching to a new one, will determine how much money you get.
