Born in Chaos

Overview

Born in Chaos is a mob-focused mod that adds over 40 hostile creatures to your world, alongside a complete set of weapons, armor, brewing ingredients, decorative blocks, and several boss encounters. Every mob has unique behavior and abilities, so fights require thought and preparation rather than simple sword-swinging. The mod is built on GeckoLib for animations and works with all biome mods, meaning these new threats will appear everywhere.

The mod introduces a new material progression centered around Dark Metal, a resource gathered from mob drops rather than mining. You will collect monster parts, craft them into Dark Metal Ingots, and forge some of the strongest equipment in the game. The mod also features a unique Naughtiness system that tracks your behavior and summons Krampus if you harm too many passive mobs.

You can browse the full list of items and crafting recipes using the tabs at the top of this page. This guide focuses on understanding the mod's progression, learning each mob's weaknesses, and making the most of the equipment and consumables available to you.

Mob Bestiary: Early Game Threats

The mod classifies its mobs into three categories: Undead, Spirits, and Other (arthropods, monsters). Each category responds differently to enchantments like Smite and Bane of Arthropods. Understanding mob types helps you choose the right weapon enchantments for each encounter.

Decrepit Skeleton & Baby Skeleton

The Decrepit Skeleton is the weakest mob in the mod at just 15 HP and 3 armor. It can only attack in melee and poses minimal threat on its own. Baby Skeletons are fast but fragile, and often serve as servants summoned by more powerful mobs like the Bonescaller. The Siamese Skeletons variation splits into two separate skeletons when below half health and drops Fused Bone, which converts to 6 Bone Meal.

Decaying Zombie & Variants

Decaying Zombies have 25 HP and 4 armor, hitting harder than vanilla Zombies. Their attacks inflict Hunger and Rotten Stink. When low on health, they shed their flesh and transform into a Decrepit Skeleton, so be ready for a second fight. Zombie variants include the Barrel Zombie (found near water, immune to drowning and sunlight, has increased armor and drops a wide range of loot), the Zombie Fisherman (attacks with rotten fish causing long-lasting Rotten Stink), and the Zombie Lumberjack (25 HP, 9 armor, carries a special axe that instantly destroys wooden Shields).

Skeleton Demoman

Similar to a Decrepit Skeleton but does not burn in sunlight. When its health drops low, it begins a detonation countdown. During detonation it stops moving, giving you a window to either finish it off or run. Prioritize killing it quickly or backing away; the explosion deals serious damage.

Phantom Creeper

The Phantom Creeper has 20 HP and behaves like a standard Creeper with one critical difference: hitting it causes it to split into two copies. Each copy can only split once. This means a careless melee attack doubles your Creeper problem. Use ranged weapons or time your attacks carefully. These spawn in the Overworld, Warped Forest, and the End.

Mid-Game Threats and Mechanics

Zombie Bruiser

One of the more dangerous regular mobs with 60 HP and 6 armor. Despite its size, the Zombie Bruiser is surprisingly agile. Its attacks knock the player back significantly and briefly stun, locking you in place. Avoid fighting near cliffs or lava, as the knockback can send you flying. Bring a ranged weapon or attack between its swings.

Skeleton Thrasher

A formidable enemy with 50 HP and 8 armor. The Skeleton Thrasher moves slowly but hits extremely hard with attacks that both repel you and briefly stun. Like the Door Knight, it can block your attacks. Use fire or Axe attacks to disable its guard, then deal damage during its recovery window. Enchanting your weapon with Fire Aspect makes this fight much more manageable.

Zombie Clown

The Zombie Clown has 35 HP and 3 armor. It attacks by smashing an Intoxicating Decoction on you, causing slowness, short-term poisoning, and dizziness. When its health drops below half, it breaks a Stimulating Decoction on the ground, buffing the movement speed of all nearby monsters including itself. Fight the Zombie Clown away from other mobs to minimize the impact of its speed boost.

Swarmer

A fly-infested zombie with 40 HP that no longer burns in sunlight. Each time you hit it, there is a chance it spawns a Corpse Fly. When killed, it explodes into a swarm of Flies, Maggots, and sometimes Bloody Gadflies. Kill it from range if possible. The Corpse Maggots that drop can be cooked into Fried Maggots (2 hunger, 0.7 saturation) or used as brewing ingredients.

Spirits

Spirits are a new mob type introduced by the mod. Most spirits disappear in direct sunlight, so surviving until dawn is a valid strategy. The Restless Spirit (24 HP) flies and shackles victims with each hit, slowing movement. The Dark Vortex (35 HP) fires projectiles that cause blindness and can reflect your ranged attacks back at you. Dark Vortex drops the essential Dark Rod, needed for Bone Handle crafting. The Scarlet Persecutors are spirits that only appear when a Cursed Mark (placed by the Fallen Chaos Knight) expires. They chase the player from 150 blocks away and make fast aerial charges. If cursed, hide in a narrow 1-block space so they cannot spawn around you.

Pumpkin Spirits and the Scarecrow System

The Pumpkin Spirit is a neutral mob found on small farms in the world. It works like an Iron Golem, attacking hostile mobs to defend its territory. However, it is extremely vulnerable to fire. If a Pumpkin Spirit touches fire, it is consumed by a flame spirit and transforms into a Seared Spirit, which becomes hostile toward you. The Seared Spirit sets you on fire with each attack and is immune to fire damage, but takes damage from water and rain.

You can craft your own scarecrow to defend your base. Build a structure from two Dark Oak Logs, a Hay Block, and a Carved Pumpkin, then right-click the Pumpkin with an Ethereal Spirit item. This spawns a Pumpkin Spirit that will guard the area. If your scarecrow accidentally catches fire and becomes a Seared Spirit, you can heal it by right-clicking with a Transmuting Elixir, which converts it into a friendly Infernal Spirit.

Mini-Bosses and Late-Game Encounters

Nightmare Stalker (70 HP)

The Nightmare Stalker is the mod's signature threat. It first appears on the third night, announced by a sound cue and chat message. It spawns completely invisible except for two glowing eyes, moves at high speed while invisible (0.28 base speed), and detects players from up to 80 blocks away. It has 70 HP, 7 armor, and 0.8 knockback resistance. When it attacks, it screams and inflicts Gaze of Terror, which causes total blindness and gradually drains your health while healing the Stalker.

The Nightmare Stalker scales with world age. Starting from day 10, it gains anti-boat mechanics preventing cheese strategies. At day 15, it gains Chilling Horror, creating dark ice under its feet and walking on water. At day 25, it unlocks Terrifying Presence, an aura that deals withering damage every 1.5 seconds when it cannot hit you for too long. You must occasionally let the Stalker land a hit (even blocked hits count) to reset this ability. At day 50 and day 100, it gains further damage and resistance boosts. The Elixir of Wither Resistance negates the Terrifying Presence damage entirely.

Lifestealer (100 HP)

A mini-boss undead that appears starting from the tenth night. It hides under a mantle and can detect players from 100 blocks away, approaching from 30 blocks. With 100 HP, 16 attack damage, 7 armor, and 0.9 knockback resistance, this is one of the most dangerous enemies in the mod. Its attacks steal your health directly with special piercing damage that ignores armor (0/1/2 per difficulty). The lifestealing effect withers you and heals the Lifestealer. Repeated hits while under lifestealing apply Death Grip, which severely slows you.

The Lifestealer can walk through water by freezing it into dark ice. Its most dangerous ability is Dark Surge: it covers itself with wings (gaining high resistance), charges for about 2 seconds, then releases a devastating area-of-effect drain. You have those 2 seconds to run out of the splash radius. If caught, you take massive damage and the Lifestealer heals 10 HP. The Elixir of Wither Resistance protects against the splash damage. Lifestealer drops its bone, which is used to brew the Elixir of Vampirism.

Missionary (150 HP)

A spirit mini-boss appearing after the tenth day. It always spawns with two Zombie Villagers. The Missionary has 150 HP, 9 armor, and full knockback immunity (1.0 knockback resistance). It fights with magical projectiles that summon Evocation Fangs at your feet on impact, can cause rain, teleport, and summon random undead. After using abilities, it enters a cooldown but gains a stunning melee AoE. The Magic Depletion effect or the Nightmare Scythe can block its teleport and summoning abilities. It drops random Charms on death.

Fallen Chaos Knight (40 HP)

Despite having only 40 HP, the Fallen Chaos Knight is extremely dangerous due to its 20 attack damage, 0.32 movement speed, and 0.9 knockback resistance. It has protection from arrows and sunlight, high armor, and places a Cursed Mark on hit. When the mark expires, up to four Scarlet Persecutors spawn around you and chase from 150 blocks. Kill the Knight quickly and find a narrow hiding spot before the mark expires.

Bonescaller & Supreme Bonescaller

The regular Bonescaller (25 HP) attacks from range with a magic staff and summons Baby Skeletons as minions. Setting it on fire or applying Magic Depletion disables its summoning. The Supreme Bonescaller (65 HP, 5 armor) is a mini-boss found atop the Dark Tower structure. It is surrounded by a bone shield that blocks ranged weapons. Destroy the shield first with melee attacks; once it breaks, the boss becomes vulnerable to arrows but summons Bone Imps more aggressively.

Krampus and the Naughtiness System

Born in Chaos introduces a karma-like Naughtiness system inspired by Don't Starve Together. You accumulate naughtiness points by killing passive animals and Villagers. Killing animals with no practical benefit (like Sniffers) awards more points, while killing baby animals or Villagers awards the maximum. You can reduce your naughtiness by fertilizing plants and taming animals.

At a moderate threshold, you will hear the sound of Krampus approaching as a warning. Cross a higher threshold and two Krampus Henchmen (nimble spirits found in cold biomes) arrive, attacking you and trying to knock weapons from your hands. At maximum naughtiness, Krampus himself appears. The Evilometer is a craftable item that lets you check your current naughtiness level. You can disable the entire system with the naughtinessMechanics game rule.

Krampus is the tankiest mini-boss in the mod at 250 HP with 14 armor and 0.9 knockback resistance. His strong attacks can knock all items from your hands, and his shield attacks deal serious damage. He summons Henchmen during the fight and, when sufficiently wounded, roars and creates a localized snowstorm. The snowstorm gradually freezes everyone nearby, slowing them and dealing damage. Maintain distance to avoid freezing. Killing Krampus drops his Horn and Bag, and reduces your naughtiness to 15% of maximum.

Boss Fights: Sir Pumpkinhead & Lord Pumpkinhead

Sir Pumpkinhead (160 HP)

This seasonal mini-boss spawns naturally only from October 25 to November 5, or can be summoned by destroying a special candle-surrounded pumpkin found in the world. The fight has three phases. In Phase 1, Sir Pumpkinhead rides his horse, attacking in melee with Soul Bundle (slows and damages on expiry), teleporting, and summoning Mr. Pumpkin minions. In Phase 2, the rider dismounts; the horse charges you with knockback while the rider shoots explosive pumpkins from range. In Phase 3, the head separates from the body. The body fights you in melee while the head shoots and teleports. Your target is the head. Victory guarantees a Pumpkin Staff drop, with chances for Holiday Candy, a Soul Saber with random enchantments, and a unique Music Disc.

Lord Pumpkinhead (666 HP)

The full boss version of Sir Pumpkinhead, summoned by right-clicking an Infernal Evil Pumpkin with a Transmuting Elixir. With 666 HP, 20 attack damage, and 12 armor, this is a late-game fight requiring maximum equipment. Lord Pumpkinhead follows the same three-phase structure but with devastating additions. Phase 1 attacks inflict Soul Stratification (slows, then damages and strips all effects on expiry) and Infernal Flame (3 damage every 2 seconds, cannot be extinguished with water, only blocked by fire resistance). Below half health, attacks switch to Living Bomb (explodes you when the effect expires).

The Lord periodically teleports, leaving behind Senior Pumpkins (stronger Mr. Pumpkins) and Pumpkin Bombs that explode in one second. In Phase 2, it dismounts and shoots its Pumpkin Pistol, setting targets ablaze with Infernal Fire. The horse stuns with each attack. In Phase 3, the head detaches and fires rapidly while the body fights in melee. Kill the head to win. Rewards include Soulbane (the strongest weapon in the mod), Pumpkin Pistol, Magical Holiday Candy, and a 50% chance of Lord Pumpkinhead's Lamp.

Weapons and Equipment

Born in Chaos adds a large arsenal of unique weapons, most crafted from mob drops and Dark Metal. Unlike vanilla weapons that follow simple tier progression, each weapon here has special effects tied to the mobs they are crafted from. The Bone Handle (crafted from Dark Rod + Dark Metal Nugget + Bone) is the universal weapon grip required for almost every recipe.

Key Weapons

The Sharpened Dark Metal Sword (1100 durability, 6 attack damage, -2.3 speed) is the standard Dark Metal weapon. It is a reliable all-rounder and your first major upgrade from Diamond. The Nightmare Scythe (700 durability, 8 attack damage, -2.9 speed) is slower but hits harder, and its attacks can block the Missionary's teleportation and summoning abilities, making it essential for that fight.

The Frostbitten Blade (1100 durability, 5 attack damage, -2.6 speed) applies freezing effects. The Intoxicating Dagger (1100 durability, 5 attack damage, -2.0 speed) is the fastest weapon in the mod and applies its namesake debuff. The Great Reaper Axe (1100 durability, 9 attack damage, -3.0 speed) is a heavy axe-type weapon that deals 9 total damage. For raw power, the Broadsword of Destruction (4000 durability, 19 attack damage, -3.2 speed) is the strongest craftable weapon in the mod but swings extremely slowly. Soulbane (3000 durability, 11 attack damage, -2.3 speed, 22 enchantability) is the best overall weapon, combining high damage with good speed, but it only drops from Lord Pumpkinhead.

Specialty Weapons

The Spider Bite Sword applies venom effects and is crafted from Spider Mandibles. The Soul Cutlass is crafted from Nightmare Claws and Dark Metal. The Dark Ritual Dagger (700 durability, 5 attack damage, -2.0 speed) is a fast dagger crafted from Nightmare Claws and Seeds of Chaos. The Spiritual Sword is built around Seeds of Chaos and Dark Metal Nuggets. The Shell Mace (400 durability, 7 attack damage, -2.6 speed) is an early option using Spiny Shells.

Holiday Weapons

The Sweet Sword (600 durability, 5.5 attack damage, -2.4 speed, 26 enchantability) and Sweet Axe (600 durability, 8 attack damage, -3.1 speed, 26 enchantability) are crafted from Holiday Candy and Cultivated Pumpkins. They have the highest enchantability of any mod weapon at 26, making them excellent candidates for enchanting. The Carrot Sword is a smithing upgrade variant with similar stats. The Icy Sweetness (2000 durability, 5 attack damage, -2.6 speed) is another smithing upgrade with high durability and freezing effects. The Stormcaller's Horn is crafted from Permafrost Shards and a Krampus Horn.

Armor Sets

The mod adds three full or partial armor sets, plus several unique headpieces dropped by mini-bosses.

Dark Metal Armor

The best armor in the mod, applied via a Smithing Table using a Dark Upgrade template. The full set provides 24 total armor points (Helmet 3, Chestplate 7, Leggings 10, Boots 4), 5.0 toughness on every piece, and 0.1 knockback resistance. This exceeds Netherite's stats. Durability ranges from 550 (Boots) to 800 (Leggings). It has 20 enchantability and is repaired with Dark Metal Ingots. The equip sound is the same as Netherite, fitting its status as endgame gear.

Nightmare Mantle of the Night

A mid-tier armor set providing 19 total armor points (Helmet 2, Chestplate 6, Leggings 7, Boots 4) with 1.0 toughness. Durability ranges from 330 (Boots) to 480 (Leggings). It requires Monster Skin and Dark Metal Ingots to craft and is repaired with either material. The Helmet requires a Nightmare Stalker Skull, meaning you must defeat the Nightmare Stalker before completing the set. This is 20 enchantability, the same as Dark Metal.

Spiny Shell Armor

An early-game partial set crafted from Spiny Shells dropped by Thornshell Crabs. It provides 10 armor points (Helmet 0, Chestplate 0, Leggings 7, Boots 3) with 1.0 toughness, but the Helmet and Chestplate provide no armor value. The set has 10 enchantability. Durability ranges from 220 (Boots) to 320 (Leggings). The Spiny Shell Trap can also be crafted to damage mobs that walk over it.

Dark Metal: The Core Material

Dark Metal is the mod's primary crafting material. Unlike vanilla ores, Dark Metal is gathered entirely from mob drops and crafting conversions. You will collect Pieces of Dark Metal and Dark Metal Nuggets from various sources, then process them upward.

Nine Pieces of Dark Metal combine into a Pile of Dark Metal, which can be smelted in a Blast Furnace to produce a Dark Metal Ingot. Alternatively, 9 Dark Metal Nuggets combine into 1 Dark Metal Ingot on a Crafting Table. Nine Ingots combine into a Dark Metal Block for storage. The Dark Upgrade template is used with the Smithing Table to apply Dark Metal armor upgrades. It requires Seeds of Chaos and Dark Metal Ingots, and the recipe produces 2 copies, so you can self-replicate your supply as long as you have materials.

Brewing and Elixirs

Born in Chaos adds a substantial brewing system with unique elixirs and potions. All advanced brews start from two base ingredients: the Chaos Component (Seed of Chaos + Water Bottle) and the Bottle of Magical Energy (Spiritual Dust + Water Bottle). From there, specific mob drops unlock powerful effects that directly counter the mod's threats.

Key Brews

The Elixir of Wither Resistance (Chaos Component + Nightmare Claw) is arguably the most important brew in the mod. It protects against the Nightmare Stalker's Terrifying Presence, the Lifestealer's Dark Surge, and Lord Pumpkinhead's Soul Stratification effects. Brew several before attempting any boss fight.

The Elixir of Insect Protection (Chaos Component + Bloody Gadfly Eye) protects against arthropod mobs and insect swarms from Swarmers. The Elixir of Ice Barrier (Chaos Component + Permafrost Shard) helps against Krampus's snowstorm ability and other freezing attacks. The Elixir of Vampirism (Chaos Component + Lifestealer Bone) grants lifesteal on your own attacks, and the Potion of Rampage (Chaos Component + Fang of the Hound Leader) provides a significant combat buff.

Standard Awkward Potion brews also work: Nightmare Claw + Awkward Potion makes a Potion of Magical Depletion (disables mob summoning abilities), Sea Terror Eye + Awkward Potion makes a Potion of Water Breathing, Intoxicating Decoction + Awkward Potion makes an Intoxication Potion, and Spider Mandible + Awkward Potion makes a Potion of Living Cocoon.

Charms and Special Items

Charms are single-use consumable items dropped randomly by the Missionary. Each Charm has 5 uses before it breaks. The available Charms are Charm of Endurance, Charm of Fury, Charm of Power, Charm of Resistance, and Charm of Stealth. Right-click to activate their effects. Since Charms are rare drops, save them for boss fights or other critical encounters.

The Death Totem is crafted from Shattered Skulls, Ethereal Spirits, and Seeds of Chaos. It functions as a second life similar to the Totem of Undying. The Dark Atrium (crafted from Lifestealer Bones and a Bone Heart) is a powerful item obtained from Lifestealer components. The Transmuting Elixir is the mod's most complex recipe, requiring nine different ingredients including Sculk Catalyst, Chorus Fruit, and Diamond. It is used to summon Lord Pumpkinhead, heal Seared Spirits into Infernal Spirits, and craft several endgame items.

Decorative Blocks and Building Materials

Born in Chaos adds two decorative block families: Black Argillite and Scorched Wood. Black Argillite is crafted from Quartz, Cobbled Deepslate, and Clay (4 per craft), then smelted into Fired Black Argillite. From Fired Black Argillite, you can stonecutter or craft Bricks, Columns, Chipped Bricks, Carved variants, Stairs, Slabs, Walls, and Pressure Plates. Adding Beetroot to a Brick creates Stained Black Argillite Brick, and adding Moss creates Mossy Black Argillite Brick.

Scorched Wood is made by surrounding Fire Dust with Logs. Scorched Logs can be crafted into Scorched Planks, which support a full woodworking set: Doors, Trapdoors, Stairs, Slabs, Fences, Fence Gates, Buttons, and Pressure Plates. Adding more Fire Dust creates Smoldering Scorched Logs with a glowing ember effect, perfect for Nether-themed or haunted builds. The mod also adds several stained glass variants (Scarlet, Purple, Orange, Green, Dark) crafted with Fired Black Argillite.

Holiday Content

The mod features seasonal content tied to Halloween (October 25 to November 5). During this window, Sir Pumpkinhead and Mr. Pumpkin spawn naturally. Outside of this period, you can still summon Sir Pumpkinhead by destroying the candle-surrounded pumpkin structures, or summon Lord Pumpkinhead by using a Transmuting Elixir on an Infernal Evil Pumpkin.

Holiday Candy drops from Pumpkinhead fights and is used to craft the Sweet Sword, Sweet Axe, and the Eternal Candy. The Eternal Candy is an epic-rarity food item that never runs out. It requires a complex recipe including Caramel Pepper, Chocolate Heart, Gummy Vampire Teeth, Mint Candy, Coffee Candy, a Transmuting Elixir, and a Stick. Each of these candies provides small food and unique effects. The Bag of Candy dropped from holiday events contains random candy items when opened.

Configuration and Game Rules

Born in Chaos uses Minecraft game rules rather than config files. You can configure these before world creation or in-game with the /gamerule command. Each mob and structure can be individually toggled. The naughtinessMechanics game rule controls whether the Krampus karma system is active. If you find certain mobs too punishing for your playstyle, you can disable them individually without removing the entire mod.

For more granular control, compatible configuration mods include Born In Configuration (mod-specific), Bad Mobs, In Control, and Spawn Balance Utility. These let you adjust spawn rates and conditions. Note that having Optifine installed may cause the mod's armor to not render visually; if this happens, check your shader settings and consider disabling entity shadows in the shader options.
