Terraria Shimmer and Pylons: how both systems work

Finding Shimmer

Shimmer is a pale purple, pearlescent liquid, and there is only one natural source of it per world.

• It sits in the Aether, a small biome that generates once, in the Underground or Cavern layer.
• The Aether always generates in the same half of the map as the Jungle. If you know which side your Jungle is on, you know which half to search.
• It is available at any point in the game — you do not need to reach Hardmode to find it.
• The Aether is Desktop, Console and Mobile content. It does not exist on the old legacy console and 3DS versions.

The practical search method is to explore the Cavern layer on the Jungle side of your map and look for the distinctive purple glow. Because it is a single small biome, a wide sweep of that half of the world is faster than digging randomly.

What Shimmer does

Shimmer is a transformation pool. Drop the right item in and it comes back out as something else.

Two restrictions catch people out: you cannot scoop Shimmer with an Empty Bucket, and you cannot fish or use items while submerged in it. Shimmer can still be moved with pumps, which is how players relocate a pool to their base.

A few notable conversions, including the ones people search for most:

Once the Moon Lord is down, the Bottomless Shimmer Bucket gives you an unlimited supply, which turns Shimmer into something you can use at base rather than travel to.

Pylon types

Pylons are teleport anchors. There are eleven types, and which one you can buy depends on where you are standing when you open the shop.

Pylon rules

The buying rules and the teleporting rules are different, and mixing them up is the usual source of confusion.

When a teleport refuses, the game gives a status message that names the reason: a pylon that is too far away, one with too few villagers nearby, or one that is not in its correct biome. Reading that message is faster than guessing. Villager happiness itself is covered on the NPC happiness page.

Building a network

Two pylons anywhere in the world is enough to start teleporting, which makes the first pair the biggest quality-of-life jump in the game.

1. Pick two high-value anchors — usually your base and whichever biome you visit most.
2. Build a real village at each. Two housed NPCs, not two wandering ones. A valid house plus a resident is what satisfies the teleport rule.
3. Buy the pylon standing in the right biome, so the correct type is offered.
4. Test both directions. Both ends need their own two villagers; it is common to build one end properly and forget the other.
5. Expand outward — Ocean, Underworld and Mushroom are the ones players typically add last, because the housing is awkward there.

Because the Aether pylon only needs Shimmer nearby rather than a specific biome, it is the easiest one to place inside a base once you have moved a Shimmer pool.

New in 1.4.5

The pylon system changed noticeably in 1.4.5, so older guides describe a stricter version of it.

• Two new pylons: Underworld and Aether.
• The minimum happiness requirement to buy a pylon was removed entirely. An NPC will sell you one regardless of how happy they are.
• Pylons can now be used during events. The old restriction that disabled them during boss fights, invasions and Frost Moon or Pumpkin Moon is gone.
• New map visualisation: opening the full map draws connections between all your pylons.
• Clicking the map now prioritises pylons over the Wormhole Potion.
• The “not enough NPCs nearby” message was clarified to say NPCs need to live near the pylon, not merely stand near it.
• Later hotfixes: 1.4.5.3 stopped pylons attracting lightning, and 1.4.5.4 stopped the Tavernkeep selling them at all.
