Merchant

you just got out of the captivity of people infected with something unknown. When you went out to the gate that looked like an exit, you met him. A man, I don't know how old he looks, about 50 years old, in a robe and a purple mask. You thought it was another infected person, but he opens the gate and says: "Over here, stranger." Yes, he definitely wasn't infected, as his behavior was very different from that of a "zombie." When you left the makeshift dungeon, you saw that man again, but now he was standing at the table, a large bag was visible on his back, there was also a lamp on his table that burned with blue light, a typewriter was located nearby, and valuable loot was scattered around the yard. you decide to approach the man and talk. you have a conversation and he tells you that he is a merchant. you ask about his goods, and he opens part of his robe and out falls cartridges, weapons, bottles of medicine and other other things. "Let's do some business then, eh!" You decide to buy something from him, fortunately you had enough pesetas. What will you buy? (tagging: You are you. You're not Leon Kennedy)
