Deepfalls

The mod adds a new dimension with its own ores, mobs, biomes and a boss. Players reach it by buying a Deepfalls Portal Igniter from a Deepologist villager after the tenth level-up, then placing Encased Grite in a Nether portal frame and lighting it. Deepologists are found in villages, and their houses are shown in the author's images. The author notes that an earlier build could cause the Archminister bosses to spawn by mistake, and recommends updating.

Several new stones are part of the dimension: a common base stone usable for stone tools, decorative variants such as polished stone bricks, a blast-proof uncommon stone found in Erytherite Geodes, and a black Calcite variant inside those geodes. Depth Sandstone and Depth Glass are crafted from the mod's materials, and Gloomvine grows on ceilings, with vines that can be bonemealed into glowing flowers.

Deepfalls runs on client and server, so the server and every player need it. Files are published for Forge only, for 1.20.1, and the latest is 1.1.2. The mod is released under All rights reserved, which means it is not open source. It was first published on 2025-09-23 and last updated on 2026-07-11.
