Traveling Merchant

The Traveling Merchant is a unique NPC vendor who randomly visits the player's town for one day. His inventory is randomized and different every visit, selling 4–10 / (average 5.47 / ; see below for details) different items listed below.

In order for the Traveling Merchant to spawn, at least 2 other NPCs must already be present. The Guide counts as one of these, but the Old Man and do not. He will not spawn during Solar Eclipses, the Goblin Army, Frost Legion, Pirate Invasion, or Martian Madness. He does not require his own house in order to spawn, and will instead spawn next to NPCs, including town pets, spending the day walking around them.

Once the criteria are met, the Traveling Merchant has a 22.12% chance of spawning each day, appearing at a random time between 4:30AM and 12:00PM. The chances of him spawning are always the same regardless if the player is sleeping. He leaves the same day at 6:00PM, but can only do so once he is off-screen. He despawns if the world is vacated any time after he spawns.

If threatened by enemies, the Traveling Merchant will defend himself with a Revolver. Once Hardmode begins, he upgrades to a Pulse Bow.

Items sold
Due to elaborate randomizer functions and dependencies upon several variables, it is nearly impossible to state an exact chance of an item being sold by the Traveling Merchant. However, it is possible to group them in six rarity "slots", ranging from "Common" to "Extraordinarily Rare". Note that these slots do not correspond to the Traveling Merchant's shop inventory slots – all sold items may be from only one slot. They are only meant to provide a rough, comparative estimate of an item's rarity. Each shop slot will roll a 1/n chance of being for every possible item where n is 100 × the rarity slot. This chance is affected by the luckiest player currently in the world. When multiple items pass this chance, the item that was tested, the latest will be the selected.

Within the slots, items higher in the list below have a marginally higher chance of being sold, e.g., the is sold slightly more often than the Water Gun (on average), because it is higher in the list.

Number of sold items
The following tables list the chances of the numbers of items sold by the Traveling Merchant. Only "base" items are counted, i.e., Dynasty Shingles and Team Platforms are excluded from this number, since they are always sold together with their "base" items Dynasty Wood or Team Block, respectively.

These chances reveal that the average number of sold "base" items is /.

Tips

 * The Traveling Merchant departs by simply disappearing while off-screen. If the player keeps him on-screen when he would normally depart, he will remain until he is off-screen again. If he is kept on-screen until dawn, he will not depart until he is off-screen after 6:00PM the following evening. This does not, however, change his inventory.
