TRIAL CHAMBERS MAP

Every other structure a Cartographer can point you at leaves some trace above ground: a temple roof through the canopy, a mansion clearing in a dark forest, a hut on stilts. A trial chambers complex has none of that. It is buried, so nothing about the surface hints at what is underneath, and digging at random is closer to mining than exploring. The Cartographer answers that with a map for 12 emeralds at journeyman, aimed straight at the nearest one.

Trial chambers are also newer than the rest of this family, added in a later update than the temples and mansions the other maps chase, so a world generated before that update only grows one wherever new chunks load. The map does not care when your world started, it just points at whatever is out there now.

It is generated against your own save the instant you pay, so the marker is yours alone, and it only solves the finding. The vaults, spawners and mob rooms inside are still exactly as much of a fight as they would be if you had stumbled onto the entrance by luck.

One seller, one price, no rival offer anywhere else in the game. The Cartographer asks 12 emeralds once he reaches journeyman, and hands back 1 map keyed to the structure specifically, not to caves or strongholds in general.

The number is written flat into the trade file, so a second Cartographer at the same tier charges exactly the same. What differs from one villager to the next is only how many of his 12 uses remain before the offer locks and waits for a restock.

Trial Chambers Map sells for as little as 12 emeralds, from the Cartographer at the Journeyman tier, and . The price is fixed rather than rolled, so a second Cartographer will quote you exactly the same.

The Cartographer at its journeyman tier asks 12 emeralds for a trial chambers map. 8 of the 72 villagers that pay emeralds, emptied out:

12 lava buckets against 312 flint for the same 12 emeralds, 26 times the carrying, and the shortest wait is the Butcher at 7.5 real minutes of shelf, gathering not counted.

A cartography table makes any unemployed villager a Cartographer the moment he claims it, but he opens at novice, two tiers short of this map. He needs to climb to journeyman, unlocked at 70 trade experience, before the offer has any chance of appearing on his shelf.

Every completed trade along the way pays experience toward the next tier, this offer included once it opens.

The slot then sells 12 maps before locking, and a villager restocks at most twice a Minecraft day, so 24 trial chambers maps is the most one Cartographer will ever produce in a single day.

12 maps empty the slot, and the villager needs 2 real minutes at his cartography table before it fills again. A Minecraft day runs 20 real minutes, long enough for two of those refills to land.

One Cartographer therefore moves 24 maps for 288 emeralds across a 20-minute day before the slot is finished until tomorrow. Buying past that number means finding a second villager rather than waiting out the same one.

A full slot runs 12 maps for 144 emeralds, and once it locks there is nothing more to buy from this offer until it restocks.

Where the emeralds come from: the same Cartographer pays an emerald for a single compass, a rate cheap enough to fund the run without a second job on the side.

144 emeralds for a full slot is enough that curing a zombie Cartographer first pays for itself. The discount lands on every price he quotes afterward, this one included, and never expires. How curing works.

Also on the Cartographer's list: item frame, banner, banner pattern (globe), woodland explorer map, paper, and empty map.

Trial chambers are copper corridors full of spawners that keep producing mobs until you clear the room, and they are underground, which makes them hard to stumble into. That is what the map is for: it points at one rather than describing it.

What is in there is worth the walk. Trial keys open vaults that hand out enchanted gear, and the ominous version of the same fight gives the heavy core that a mace is built around.

The map behaves like every other explorer map: it finds the nearest chamber to where it was made and marks it once. Carry it and it fills in the ground you cross on the way.

The Trial Chambers Map costs 12 emeralds and a compass from the Cartographer, and it only gets you to the door. Inside, the trial spawners can be farmed for their loot and for breeze rods: How to Farm Trial Spawners in Minecraft (Trial Chambers).
