Dungeon Descent

Dungeon Descent

Deep beneath the surface lies the Cursed Underhold—a sprawling five-floor dungeon filled with ruined halls, deadly creatures, powerful bosses and forgotten equipment.

Explore increasingly dangerous floors, discover safe rooms, defeat the rulers of the Underhold and use their remains to forge equipment capable of carrying their power.

The Cursed Underhold

Cursed Underholds generate naturally underground. Each dungeon contains five connected floors with distinct themes:

Floor I — Bone Crypts and Ruined Barracks Floor II — Prisons, Forges and Execution Chambers Floor III — Fungal Rot and Corrupted Gardens Floor IV — Ancient Quarries and Seismic Ruins Floor V — The Burned Palace and Ashen Cathedral

The dungeon includes branching corridors, combat rooms, loot chambers, traps, collapsed passages, environmental storytelling and hidden details.

Safe rooms provide checkpoints throughout the descent. Their teleporters can be activated after defeating the final boss, allowing you to return to previous floors and collect anything you left behind.

Bosses

Each floor ends with a unique boss encounter:

The Twinbone Sentinel — an unnatural two-headed guardian of the crypts. The Iron Gaoler — a brutal jailer armed with chains and a massive hammer. The Rotbound — a corrupted creature that spreads poison, decay and swarming mites. The Deepstone Colossus — an ancient stone giant with crushing seismic attacks.  The Ashen King — ruler of the deepest floor, wielding fire, ash and overwhelming melee power.

Each boss has its own arena, attacks, mechanics, equipment theme and crafting fragments.

Permanent Artifacts Defeating the Ashen King allows you to select two permanent artifacts from six possibilities. You cannot choose the same artifact twice during one dungeon completion.

Twinbone Emblem — increases attack speed, protects against projectiles and grants a cooldown-based double jump. Gaoler’s Broken Shackle — provides knockback resistance, shortens negative effects and grants temporary resistance when critically wounded. Rotheart Seed — grants poison immunity and emergency healing below half health. Colossus Core — increases armor and maximum health. Ashen Crown Fragment — grants fire immunity and increased melee damage. Emberstep Seal — increases movement speed, grants a burst of speed after taking damage and can clear rainy weather on a 30-minute cooldown.

These artifacts are designed for Curios slots.

Boss Souls and Temporary Relics Bosses award Boss Souls, a currency used in the relic shop.

Press H to open the shop and browse a collection of weaker consumable artifacts. These relics provide useful combat, exploration, healing and utility effects, but have limited uses.

The Soulforge Anvil Defeating the Ashen King awards a Soul Core. Use it on a vanilla anvil to transform the block into a Soulforge Anvil.

The Soulforge contains three systems:

Awaken — permanently unlock all armor, weapons and tools associated with a boss by consuming that boss’s permanent artifact. Forge — combine Netherite equipment, physical Boss Fragments and Boss Souls to create boss equipment. Repair — repair damaged boss equipment using its corresponding fragments.

Boss Fragments are physical drops that must be placed into the Soulforge manually. 

Boss Equipment Every boss has a complete equipment collection with custom models and textures.

Equipment includes:

Five increasingly powerful armor sets Boss-themed swords and heavy weapons Specialized pickaxes The Rotheart poison staff The Colossus maul The Ashen Greatsword The Ember Bow Additional tools tied to each boss

Armor strength increases with dungeon progression, beginning above Netherite and becoming stronger with each set.

Wearing two matching armor pieces grants a smaller set bonus. Wearing all four pieces activates the complete boss ability. Certain full sets provide active powers, including the Ashen set’s combat dash.

Boss equipment supports its appropriate Minecraft enchantments and uses normal durability. It can be repaired through the Soulforge without consuming Boss Souls.

Specialized Weapons Some equipment has unique mechanics:

Rotheart Staff — releases a poisonous, withering stream or launches a damaging green glob. A glob that strikes the ground contaminates a 3×3 area for five seconds. Colossus Pickaxe — mines a 3×3 area and uses normal durability. Ember Bow — draws faster than a vanilla bow and belongs to the Ashen equipment collection. Ashen Pickaxe — a fiery mining tool with normal durability. Ashen Greatsword — a large, detailed weapon forged from the power of the final boss. Dungeon Rooms

The Underhold is more than a collection of empty combat chambers. Its layouts include:

Crypts and burial halls Ruined barracks and armories Prison cells and execution rooms Workshops and forges Storage rooms and abandoned camps Loot rooms, traps and secret-wall clues Safe rooms with beds and teleporters Unique miniboss arenas and a final throne room Progression

Progression through the dungeon is sequential, with each floor introducing stronger enemies, more dangerous environments and better equipment opportunities.

**The Underhold Delver’s Journal ** Every new player receives the Underhold Delver’s Journal. Another copy can always be found in the supply barrel at a dungeon entrance. The journal is a guide for the player, explaining the dungeon, its bosses, artifacts, equipment, and progression.

If the journal is lost, it can also be crafted using:

Prepare carefully, descend through all five floors and challenge the Ashen King. One victory cannot provide every permanent artifact—those who want the full power of the Underhold must return and conquer it again.
