Traveling Merchant

The Travelling 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 Travelling 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 Travelling Merchant has a 22% chance (roughly 1 in 5) of spawning each day, appearing at a random time between 4:30 AM and 12 PM. He generally stays for only one day at a time, after which he leaves at 6:00 PM. He despawns if the world is vacated before that time.
