Well, Memeroon has done it again... last time you asked him for a hoplon, and he sold you a frying pan. Now you ask him for a rusty axe and he sells you a rusty spear. Is the Qiqirn hard of hearing, or is he just messing with you?
At any rate, considering how cheap you're getting these Scavenged Gear items, you can't bring yourself to complain, and thus you walk away with your new and unexpected posession.
If you like silly mods like these and want to see more, consider donating to my Ko-fi! Even 1 USD would help me justify the time I spend on these ^^
