Traveling Merchant

The Traveling Merchant is a unique NPC vendor who randomly visits the player's Town for a day. His inventory is randomized and different every visit, selling a small selection of the items listed below.

The Traveling Merchant can only spawn once you have at least 2 other Town NPCs, and only on days when no Events are occurring. He does not need his own house in order to spawn, and will generally spawn near existing NPCs, spending the day walking around near them.

Once the criteria are met, the Traveling Merchant has a 1 in 5 chance (or 22%, more accurately) of spawning each day, appearing at a random time between 4:30 AM and 12 PM. He stays for only one day at a time unless he is constantly on the screen, in which case he will never leave until you take the screen off him, after which point he will leave at 6:00 PM. If the world is vacated before that time he will not be there when someone logs back on.
