Your goal as a merchant is to transport goods from one town to the next in Silkroad. You buy certain items for cheap in one town and take them to another town to sell for profit.
It lists their buy price and their sell price. Notice what a big difference in profit The further away the town, the more profit you make.
Merchants increase their merchant level upon delivery of goods. The higher your merchant level is, the more value each star trade is worth. Bascially, a level 1 merchant would be able to trade 10k in items on a 1 star trade.
A level 4 merchant would be able to trade 30k in items on a 1 star trade. This applies for all star trades. The numbers used were just examples, they are not the in-game values.
Hunters
Your goal as a hunter is to protect the merchant from hostile thieves. Most merchants hire hunters to protect them on their caravan. There is no point in spending all their money on items, if they can’t even make it to the other town without getting robbed In which case, they would lose money and make zero profit.
I think that’s why they make the buy price so low, haha. It may take a few tries to succeed. That is why the hunters are so valued.
Your JOB level exp is gained when you succeed in your job goal. Merchants, delivering items to town. Thieves, robbing caravans, killing merchants/hunters. Hunters, killing thieves.
