Incendium Legacy
A nether biome overhaul combined with challenging structures to conquer, unique weapons to obtain, and tricky mobs to defeat.
About this Mod
Incendium
Incendium is a datapack that completely revamps the nether, way more than what Minecraft did in the 1.16 Nether Update.

Notes
- Incendium has an optional resourcepack called Sparkles! This is not required, but it allows all items to have their own beautiful textures.
- Incendium is not compatible with Amplified Nether
- Do not add this to an existing nether - reset yours first, or use a new world
- View the structures and biomes per seed using jacobsjo's Minecraft Datapack Map
Description
Biomes
Incendium adds 8 unique biomes to the nether. Do you bravely venture through the perilous Quartz Flats, wander the mysterious Withered Forest, or battle your way through the steep Infernal Dunes? Each biome has a unique personality and story to tell. With unique block themes in each biomes, opportunities for new farms for technical players, 3D biomes, and stunning terrain, there is truly something for everyone.
Structures
To complement the lovely biomes, there are 9+ structures for you to explore and conquer. In the Ash Barrens, the Forbidden Castle stands forebodingly, with courageous Piglins defending its treasured loot - one of the largest and complex random structures in Minecraft! Alternatively, you can conquer the ominous Sanctum with its illagers defending dark secrets and strong weapons. The skeleton chef Torte defends his Quartz Kitchen, and the Withered Director his Nether Reactor. What will you conquer first?
Items
Every mob you defeat and structure you conquer has its reward - Incendium pays you handsomely with rich loot and custom weapons! Defeating the Hovering Inferno could earn you the Trailblazer - a flame-spewing bow. A high damage, but taxing Greatsword of Sacrifice hides within the Forbidden Castle's walls, along with the helpful Hefty Pickaxe. Or maybe you prefer to find the Hazmat Suit to protect you from all types of poisonous attacks. There are over 25 items to forge your own playstyle with!
Mobs
No datapack would be complete without its own mobs to fight you. The Toxic Heap is home of the agile Toxic Slimes, and the Withered Forest is haunted by the Restless Spirits. On the other hand, you could go on a rescue mission to save the Ghastling from the Abandoned Tower - in return, it will defend you from Ghasts. If none of this is challenging, you can summon the all-powerful Hovering Inferno boss for a difficult and dirty battle.
