DeCubed Dungeons (Formerly Dungeons+)
by technodono
With DeCubed Dungeons installed, vanilla-style underground dungeons are replaced by biome-specific designs, each with its own mob spawner type.
What it does
The mod replaces the standard dungeons of the base game with more than 30 new underground dungeons and structures. Each type keeps the look of the vanilla dungeon while differing in layout and in the spawner it contains, and each type generates only in certain biomes. Standard dungeons draw on the vanilla loot tables, so they fit most modpacks.
Ancient city remnants use a separate loot table with fewer rewards than the base ancient city tables. Dungeons also spawn inside certain biome sets from other world generation content. The mod is a data pack for Fabric, Forge, NeoForge and Quilt, and the server needs it while the client may skip it. Files cover 1.19 – 26.3, and the latest build, 1.13.1+mod, is for 26.3 and dates from 2026-09-19. It is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source.
Other world generation data packs can prevent some dungeons from generating in their custom biomes, according to the author.
Key features
Biome-specific dungeons
Dungeon types are placed only in certain biomes, so each region of a world gets its own underground designs.
Unique mob spawners
Each dungeon type contains a spawner of its own, which supports structure exploration with different enemies.
Vanilla-style loot
Standard dungeons use the vanilla loot tables, so their rewards stay close to the base game.
Ancient city loot variant
Ancient city remnants draw on a separate loot table with a reduced set of rewards.

Use cases
Exploring new underground areas
Players who want more places to search can find dungeon types that differ from vanilla in each biome.
Who it’s for: Players who run a server or a world with other world generation data packs, and who want the dungeons placed by biome and checked for compatibility with those packs first.
How it compares
Extra dungeons runs on Fabric, Forge and NeoForge with a client and server environment, for 1.20.1 – 1.21.11, under All rights reserved and not open source. Epic Structures: Dungeons is server required with client optional, covers 1.19 – 26.3 on Fabric, Forge, NeoForge and Quilt, and is also under All rights reserved. Neither is a data pack in the same way, so the choice depends on loader and version.
