Pylons



Pylons are furniture items that allow a player to teleport to any other pylon, by either selecting the pylon or by finding a pylon in the fullscreen map.

The following restrictions apply:
 * Pylons can only be used when there are 2 or more living, housed NPCs (including the Old Man or town pets) within a 169 tile wide by 124 tile high rectangle centred on each pylon.
 * At least a portion of the NPCs' housing tiles must be within this range, but the pylons will still work if the NPCs themselves walk out of this range.
 * Pylons are only practical if there are 2 or more in the world. The system they form is known as the Pylon Network.
 * Pylons only function when in their respective biome.
 * Only one of each type of pylon may be placed in a world.
 * The Pylon Network cannot be used during Boss battles or when invasions are announced or in progress.
 * Players must be within interaction range of a pylon (5 blocks) to teleport using the Pylon Network.

Pylon shops


Most pylons, with the exception of the Universal Pylon, appear in NPC inventories when the following conditions apply:
 * The NPC is a "vendor" that normally sells items, other than the Traveling Merchant and the Skeleton Merchant.
 * The NPC must be happy.
 * The simplest way to ensure this is to house them within 25 blocks of an NPC they love (ie: The Tavernkeep loves the Demolitionist).
 * An NPC who likes their houses biome can be housed with an NPC they merely like, and still sell the pylon (ie: The Merchant likes the Nurse and also likes the Forest).
 * These tips assume the player avoids factors that detract from happiness such as overcrowding, disliked NPCs and disliked Biomes.
 * The player is not in an evil biome (Corruption or Crimson).
 * The table below indicates which NPCs can be housed in the biome appropriate to the pylon (at a distance from other NPCs) to ensure that one of them is happy enough to sell the pylon. One of the NPCs may be happy enough to sell the pylon if housed alone, but a second NPC needs to be housed nearby to operate the pylon. These are only examples and aren't a complete list of every combination that can be used to obtain a pylon.

Although the listed cost for all biome pylons is, they are only sold if the shopkeeper has a price modifier of 85% or less (due to happiness etc.). As a result, the actual price will be between and.

A hybrid biome can result in multiple pylons appearing in the NPC's inventory, except the Forest and Cavern, which are mutually exclusive and only available when not in the Snow, Desert, Ocean, Jungle, Hallow, or Glowing Mushroom biomes.

Tips

 * Building your Cavern Pylon town immediately outside the Dungeon has many benefits, the most obvious being near-instant access to a deeper part of the Dungeon once Skeletron is defeated.
 * You can still build the town prior to Skeletron, as the Dungeon Guardian will not spawn unless a player is actually inside the Dungeon.
 * Since the Dungeon is right next to the Ocean, this means both oceans can be conveniently accessed, so long as your Ocean Pylon is at the opposite ocean from the Dungeon.
 * If you have at least three NPCs, part of the Dungeon may be considered part of your Town instead. While it isn't likely to be a large part, it can give you a relatively safe place to deal with enemies without more immediately spawning. (Note that this will work even if the town doesn't contain a Pylon.)
 * Later in the game, you won't need to worry about accidentally triggering a battle with the Lunatic Cultist, as you'll more likely enter the dungeon via your own entrance than the naturally-spawned one.
 * Aside from the practical benefits, it also provides unique scenery for both the Town and the Dungeon.
 * This strategy is not recommended in multiplayer games, where a player in the Dungeon can potentially cause Dungeon enemies to spawn within range to teleport to or attack players in the Town.
 * Alternately, building the Cavern Pylon at the top of the Underground layer near the player's main base may be convenient, especially in multiplayer or when all players have some form of Magic Mirrors. This allows the player to Hallow their base area without reshuffling pylons, if desired. A Dungeon town can then use the pylon of whatever Surface biome it is located in, often Forest, allowing quicker access to the Ocean but still quick access to the Dungeon.
 * Another use for the Cavern Pylon is to put it in or near the Underworld, providing a viable alternative to a conventional Hellevator.
 * The Universal Pylon uniquely works anywhere, and perhaps more usefully, does not require NPCs nearby. It can effectively be a free infinite-use Potion of Return for a player carrying it.


 * Assuming you have built a singular house for the Truffle NPC, you will not be able to use the Mushroom Pylon, as there aren't enough NPCs near it.
 * One way to easily fix this without building another house is to have a Town Pet move in with the Truffle.
