Hexerei Biomes and Structures Guide

Biomes

Willow Swamp is the primary biome added by Hexerei. It has a temperate climate with a temperature of 0.8. This biome supports standard passive mobs such as sheep, pigs, chickens, cows, and frogs. Hostile mobs that spawn here include spiders, zombies, zombie villagers, skeletons, creepers, and slimes.

Structures

Hexerei adds several structures, each tied to a specific vanilla biome and with its own spacing rules. All generation attempts are measured in chunk regions, and the minimum distance between two instances of the same structure is enforced to prevent them from clustering.

Baba Yaga Hut

• Biome: Forest
• Placement: One attempt per 100x100 chunk region
• Minimum separation: At least 95 chunks apart

This is the rarest structure in the mod, with a very low attempt rate per region. You will need to explore large forest areas to find one. The large minimum distance means that finding a second hut after locating the first will require a long journey.

Nature Coven

• Biome: Forest
• Placement: One attempt per 29x29 chunk region
• Minimum separation: At least 11 chunks apart

This structure appears more frequently than the Baba Yaga Hut but is still uncommon. It shares the forest biome with the hut, so you may encounter both while searching the same general area, though the spacing rules apply separately to each structure type.

Owl Post Office

• Biome: Forest
• Placement: One attempt per 20x20 chunk region
• Minimum separation: At least 12 chunks apart

The Owl Post Office has the highest attempt rate among the forest structures. Because its minimum separation is 12 chunks while its attempt region is 20x20, multiple post offices can exist within a single large forest, but they will never appear too close together.

Dark Coven

• Biome: Swamp
• Placement: One attempt per 29x29 chunk region
• Minimum separation: At least 11 chunks apart

This structure is the swamp counterpart to the Nature Coven, using the same placement frequency and spacing. It does not generate in the Willow Swamp biome, so you must look in standard vanilla swamps to find it.

Witch Hut

• Biome: Swamp
• Placement: One attempt per 20x20 chunk region
• Minimum separation: At least 8 chunks apart

The Witch Hut is the most common swamp structure, matching the Owl Post Office's attempt rate. Its minimum separation is the smallest of all Hexerei structures at 8 chunks, meaning you can find several of these within a reasonably sized swamp.

Search Tips

When looking for these structures, remember that forest structures will never appear in swamps, and swamp structures will never appear in forests. The Willow Swamp biome does not contain any of these structures; they are all restricted to the vanilla forest and swamp biomes. Use the spacing rules to estimate how far you need to travel between finds. For the Baba Yaga Hut specifically, be prepared for an extended search, as its attempt rate is far lower than any other structure in the mod.
