Swamp Hut
Page updated
A swamp hut, often called a witch hut, is a small wooden house that generates with a witch and a black cat. Its special witch spawning rules make it a good farm site, and some players visit to tame the cat.
This guide follows vanilla Java 26.3. Historical changes retain their own edition and version. Bedrock generation and loot can differ. Screenshots and verified seeds below retain their own game versions.

Where it generates in Java 26.3
Swamp is the only biome in the Java 26.3 hut tag. Mangrove Swamp is not included. [2][5]
Candidate positions and rarity
Java 26.3 selects one potential starting chunk per 32×32-chunk region (512 blocks on each side). Candidate selection happens before successful structure generation; this is not a measured density or an average travel distance. [3][4]
The generation entry point samples the world-surface heightmap and creates a swamp-hut piece in the starting chunk. Piece placement, rather than a fixed global Y value, determines the final hut position. [1][3][4][5]
What the starting position means
Huts have their own 32×32-chunk candidate grid. Their salt differs from other structures with the same spacing, so equal grid sizes do not mean their candidate coordinates coincide. [1][4][5]
A single raised hut
The hut is one compact wooden room on log supports, with a porch, a stair-block roof, a crafting table, a cauldron and a potted mushroom. It has no generated loot chest or basement. The support columns extend down to meet the terrain. [7]
The piece separately attempts to place a persistent witch and cat at its resident position. Saved flags prevent those construction steps from repeatedly creating residents when the piece is processed. [7]
Resident witch versus later spawns
Java also gives the hut a witch monster-spawn list and a cat creature-spawn list within its piece bounds. That is separate from its initial residents. A cleared or dismantled-looking hut can still matter for mob spawning when the relevant conditions are met. [6]
The small visible building is therefore useful as a locator, but its physical walls do not describe every requirement of a working witch farm. This guide does not treat the presence of the hut alone as a tested farm design. [6]
Loot and rewards in Java 26.3
The Java hut placement builds a crafting table, cauldron and potted red mushroom, then attempts a witch and cat. It does not create a loot chest. The furniture and residents are different reward sources from randomized container loot. [8][9]
The inspected witch table gives redstone its own one-roll pool with a baseline count of 4-8. The first pool makes 1-3 selections among glowstone dust, sugar, spider eye, glass bottle, gunpowder and sticks; the first five weigh 1 each and sticks weigh 2. Each selected entry can produce 0-2 items before Looting, so selection is not a guarantee of a positive drop. [8]
Looting uses enchanted_count_increase modifiers on these drops. The table is an entity-drop rule, not a rate of drops per hut or a tested witch-farm output rate. Bedrock cauldron behavior is outside this Java audit. [8]
| Item | Where the rule applies | What the data establishes |
|---|---|---|
 Redstone | One witch entity-loot invocation without Looting | 4-8 redstone from its separate pool. [8] |
 Glowstone dust | First witch pool without Looting | Weight 1 of total 7 over 1-3 selections; each selection can supply 0-2 items, so no positive-drop percentage is inferred. [8] |
Version history and release dates
These milestones retain their edition and exact build labels. Snapshot, beta and preview dates belong to those development builds; full releases and staggered Pocket platform releases are dated separately. Historical introduction claims come from the cited Wiki history. [10]
