Pylons



Pylons are furniture items that appear as a large stone or crystal hovering and rotating above a biome-themed stand. They allow a player to teleport to any other pylon by pressing the button on them, which will open the fullscreen map, and selecting the other pylon there.

The following restrictions apply:
 * Pylons can only be used when there are 2 or more living, housed NPCs (including the Old Man and town pets) within a 169-tile wide by 124-tile high rectangle centered 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 will not work if an NPC is not near their home.
 * 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 (excluding the Lunar Events).
 * Players must be within interaction range of a pylon (pylon must be within visible distance) to teleport using the Pylon Network.
 * The Pylon Network cannot be used to travel long distances without opening the fullscreen map.

Purchasing pylons


Most pylons, with the exception of the Universal Pylon, can be purchased from NPCs when the following conditions apply:
 * The NPC is a "vendor" that normally sells items, other than the Traveling Merchant and the Skeleton Merchant:


 * The vendor NPC must be happy, with a sale modifier of 90% or better.
 * Remember that NPC relationships are not always symmetrical, but only one vendor needs to be happy enough to sell the pylon. The NPC they like (who helps make them happy) does not even need to be a vendor.
 * The "solitude" bonus gets most of the way there, granted by having at most one other NPC within 25 tiles, and at most three more within 120 tiles. Given this, it is enough to place a vendor in a biome they like, or with an NPC they like, while avoiding crowding or any biome or neighbor that they dislike.
 * In a more crowded area, bonuses can be stacked; e.g. an NPC who loves their biome, and at least likes their only close neighbor (or vice versa), can be happy enough even if there are too many NPCs within 120 tiles to get the solitude bonus.
 * There must be another NPC near the vendor NPC.
 * The player is not in an evil biome (Corruption or Crimson).
 * Note that happiness only matters while purchasing a pylon. To use the pylon, two NPCs need to be housed nearby, but neither needs to be the one who sold the pylon, and their happiness is no longer relevant for the Pylon Network.
 * 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.

The table below indicates which NPCs could 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. These are only examples and are not a complete list of every combination that can be used to obtain a pylon.

Tips

 * Pylons can be used during the Lunar Event to traverse the world to combat the various pillars. This exception does not include Moon Lord, and they are still unusable during other invasions/boss fights.
 * Early access to all pre-hardmode pylons can be gained from the first NPCs available without defeating a single boss: The Arms Dealer with The Nurse sells all pylons.(This includes the hallow Pylon if you are playing Celebrationmk10 seed).
 * The Pylon Network can be supplemented by several other forms of teleportation or transportation, all of which do work during boss fights and invasions:
 * Each player can use a Recall Potion, Magic Mirror, or Cell Phone or Shellphone to teleport to their own spawn point or Oceans, or The Underworld. (Use while fighting the Wall of Flesh will result in an instant death unless you teleport to the center of the underworld).
 * The Shellphone gives access to both Oceans (use once for the currently more distant Ocean, then again for the other Ocean). It will take the player to the furthest point with a solid block or platform at the surface. It also  gives access to the center of the Underworld (it may be necessary to build a platform there).
 * In Hardmode, each pylon plus the three conch landing points, can be used as the hub of a local Teleporter network.
 * Even before Hardmode, the pylons and conch points can also be rail hubs.
 * Pylons cannot work with solitary houses. One way to easily work around this without building another house is to have a town pet move in with the NPC in that house.
 * As there are three town pets, this strategy works with a maximum of three standard pylons per world (excluding the Universal Pylon).
 * Since the area that the Cavern Pylon can be used in is very large, there are several possible use cases for it:
 * Creating a 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.
 * It is still possible to build the town prior to defeating Skeletron, as the Dungeon Guardian will not spawn unless a player is actually inside the Dungeon (more specifically, when the player is in front of natural Dungeon Brick Walls).
 * Since the Dungeon is right next to the Ocean, this means both Oceans can be conveniently accessed, so long as the Ocean Pylon is at the opposite Ocean from the Dungeon.
 * If there are at least three NPCs, part of the Dungeon may be considered part of the town instead. While it is not likely to be a large part, it can provide a relatively safe place to deal with enemies without more immediately spawning. (Note that this will work even if the town does not contain a pylon.)
 * Later in the game, the player will not have to worry about accidentally triggering a battle with the Lunatic Cultist, as it is more likely they enter the Dungeon via an 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 setup 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.
 * A third-party world-editing program can be used to circumvent the one-of-each-pylon rule. Additional pylons will function normally, as long as enough NPCs are present.
 * It is possible to have 3 different Pylons appear in one NPC's shop.
 * Example: Jungle, Mushroom and Hallow Pylons appearing at the same time; This was obtained due to there being an artificially created mushroom biome in a jungle while having the Hallow be near the jungle-mushroom biome. Some other combinations may be possible, However.

Trivia

 * While pylons will still hover and rotate when the game is paused, they will only hover when the game is "tabbed out".
 * Pylons resemble the Protoss building of the same name in.
 * Additionally, this is also referenced in a bit of flavor text on the Universal Pylon.
 * The maximum price for a non-universal Pylon is . This is because even though all non-universal pylons have a base value of, due to the fact that the NPC that one is buying from must have at least a 90% price modifier from happiness for the NPC to sell the pylon, a pylon can normally not be bought for its base value; however on the remix seed and everything seed npc happiness is disabled, and thus pylons will be sold for its base 10 gold value.
