Deep Fire Update
by itzfedd
Deep Fire Update changes the Nether with new ores, biome-based finds, tools and armor made from Pyrite Crystal and Red Diamond.
What it does
Pyrite Ore appears in the Nether Wastes biome and Sulphur Ore in the Basalt Deltas, so exploring those biomes gives the materials the mod uses. Red Diamond Ore is found in both Nether Wastes and Basalt Deltas. Pyrite Crystal is made from Pyrite Ore, and Red Diamond Ore Block is made from Diamond and Red Diamond Ore.
The crafting paths run through smithing tables. A Pyrite Axe combines a Pyrite Ore block with a Sulphur Iron ingot, and a Pyrite Shield takes a diamond axe, Pyrite Crystal and Sulphur. Red Diamond armor and weapons are built from nine Red Diamonds plus Pyrite Crystal. Soul Magmablock is made in a stonecutter from Netherrack, and a blue magmablock turns up in Soul Sand Valley.
The mod is published for NeoForge only, and the files cover 1.21.8 – 26.1 across five release versions: 1.21.8, 1.21.9, 1.21.10, 1.21.11 and 26.1. The latest file is 1.0.0 for 26.1, dated 2026-03-30. The code is not open source and the author keeps all rights reserved. Both the server and every player need the mod, since the environment is client and server.
