Borda is a travelling vendor in the Xvart Village area west of Nashkel at 680, 1610. He will immediately approach the protagonist or their party and offer a few magical items for sale, through dialogue. You will be unable to sell him anything, and only be able to buy a single item, but be aware - the things he sells are all cursed. The alternatives are turning him down or try to rob him; the former ques his exit, while the later starts hostilities. You can steal he 5 times, you get the three items he is selling and web scroll (not cursed) + Color Spray scroll (not cursed).
