How about a trader

you give them certain items and they give you others in exchange (duh)

for example you give them red ice and they give you purple ice and vice versa (of course which of these displayed depends on if you had crimson or corruption in your world, if you had crimson you would have to give them red ice for purple ice and vice versa).It would also allow you to trade the guide voodoo doll for the clothier voodoo doll. Perhaps various monster banners for each other on a blood moon
