Rare Merchant in Arcadia Town

Own

Moderator
Since the dawn of arcade it has been a problem that you're not able to get cosmetic hats, furniture or other items exclusive to Story Mode.

Most of the furniture options cut off at Mt. Bloom due to the fact that the housing in arcade hasn't been updated since Arcade Mode was finished, but I'm assuming that's an oversight. I'm talking more about the furniture you dig up in treasure maps, or find in chests.

How to fix the problem with minimal effort?

The Rare Merchant!

After you have beaten arcade mode even once, your runs now have a chance to spawn a merchant in Arcadia for that specific instance of returning to town, using your town gold as a resource.

A good way to balance it would be the floor your run ended on as a %, requiring a minimum of Floor 5 for the merchant to show up in Arcadia. You die on floor 10? It has a 10% chance to appear.

The merchant stock would ideally include things like:
Spring Charm
Winter Charm
Spider Charm
Cat Screen
Bonsai Tree
House Plant
Wall Clock
Potted Plants (the ones that turn into enemy house plants - if Farmer Oak can't just sell those)
Season Orb
Housing Wisp
Housing Statue
Dungeon Paintings
Ghost Ship Haunted Furniture Shop
Seasonne Tree Furniture Shop
Ambience Box
Festival Cutouts
Pure cosmetic equips like Ski Goggles, Party Hats, Bows, etc.
