Dungeon Conquest API
by leoncer1994
Dungeon Conquest API is a Forge library that generates large instanced dungeons from datapacks, and it is the base that the Dungeon Conquest: Stormborn Tomb mod builds on.
What it does
The API creates instanced dungeons: each dungeon is placed in its own dedicated dimension, which keeps very large structures out of the main world. Structures are defined through datapacks, so a pack maker can add renewable dungeon structures without changing code. A structure's NBT file is paired with a JSON file that tells the API to recognize it as a dungeon. The approach is inspired by the Fabric mod Dungeonz.
Dungeons are linked to the overworld by a portal. Players can enter and leave freely, and their progress is kept between visits. After a dungeon is created, a 5-hour countdown starts. When the dungeon is deleted, it can be regenerated with refreshed mobs and loot. Players still inside when cleanup is scheduled are given a 20-minute delay before the reset. Dungeon Conquest: Stormborn Tomb requires this API, so it is installed alongside it.
The mod is published for Forge only, for Minecraft 1.20.1, with 2.0.0 as the latest file, released 2026-09-30. It runs on client and server, and the code is under the MIT License, so it is not open source. The first file appeared on 2026-07-27.
Key features
Instanced dungeon dimensions
Each dungeon is generated in a dedicated dimension, so large structures do not weigh on the main world.
Datapack-defined structures
New dungeon structures are added through datapacks, with an NBT file and a JSON file that identifies the dungeon.
Portal access and saved progress
A portal links each dungeon to the overworld, and players can come and go while their progress is preserved.
Timed regeneration
A 5-hour countdown after creation leads to deletion, after which the dungeon regenerates with fresh mobs and loot.
