About BlightedWorldHeart

From Thunderstore

A massive raid-boss mod for Valheim using TheHive prefab. Spawns the Blighted World Heart, summoning endless waves of enemies, unique Sub-Bosses, and dropping dozens of new custom weapons and armors with Poison, Spirit, and Defense affixes.

🫀 The Blighted World Heart

A dynamic, massive raid event that violently transforms your serene surroundings into a blood-soaked warzone. Only the strongest Vikings will survive.


🌑 The Corrupted Core

Forged from the twisted remains of "The Hive," the Blighted World Heart beats with a sinister, pulsating malice. This towering abomination anchors the nightmare, serving as the nucleus of the raid and the prime target your clan must annihilate to stem the tide of darkness.

🩸 Universal Desecration

No sanctuary is safe. This cataclysm can be invoked at any existing vanilla boss altar.

By sacrificing the required biome-specific trophies, you corrupt the ancient stones, tearing open a rift for the Blighted World Heart to erupt into existence. Transform any boss spawn in your world into a legendary battleground!


🌪️ Biome-Dynamic Onslaught

The Blighted World Heart is a living, adapting nightmare. It bends the very environment to its will depending on where it is unleashed:

  • Twisted Visuals & Mechanics 🎭 - The Heart warps its horrific appearance and deadly characteristics to mirror the biome it infests.
  • Relentless Hordes 🧟 - The endless, surging waves of enemies are ripped directly from the local environment. A Heart in the Black Forest will unleash suffocating swarms of Greydwarves led by towering Trolls, while a desecrated altar in the Plains will crush you beneath a stampede of bloodthirsty Fulings and enraged Loxes.
  • Monstrous Sub-Bosses 👹 - When you strike the Heart and shatter its health thresholds, it retaliates by summoning colossal, biome-dependent Sub-Bosses. These behemoths offer unique, devastating mechanics tailored to break your spirit.

✨ Epic Features

  • The Blighted World Heart: A corrupted monstrosity summoned via dark sacrifices. Once awakened, it unleashes an unrelenting, endless tide of foes. Survive, or be consumed!
  • Nightmarish Sub-Bosses: As the Heart bleeds, it calls forth scaled-up champions of the horde (e.g., furious 2-Star Loxes, titanic Trolls, and terrifying Seekers) that must be slaughtered to proceed.
  • Legendary Custom Loot System: Triumph over the Heart to claim the ultimate prize: Blighted Gear. Discover over 360+ incredibly rare, unique Blighted variations of Vanilla weapons and armors, forged in the heat of battle — including the full Valheim 1.0 Deep North set of Frost-Fire gold weapons and Deep North armor!
  • Dynamic Multiplayer Scaling: The spoils of war grow with your warband. The Heart guarantees 3 legendary loot drops upon its destruction, plus 1 additional artifact for every Viking brother or sister who stood by your side.
  • Fully Server Authoritative & Synced: Forged for dedicated realms. Every brutal config value is locked in server-side and automatically synchronized via Jotunn.
  • Sleek Custom UI: Keep your eyes on the prize with a beautifully dynamic Boss Health Bar that relentlessly tracks the Heart and its summoned Sub-Bosses.
  • Wacky's Database Compatibility: Safely customize the stats, recipes, and requirements of any Blighted Item using Wacky's Database! WackyDB is auto-detected on startup, handing full authoritative control of Blighted Items over to your YAML configurations. A Blighted recipe with a WackyDB YAML (name: Recipe_Blighted...) is left entirely to that YAML; every other Blighted recipe keeps its normal upgrade cost. Blighted items stay drop-only (hidden from the Craft tab) until you give one a real level-1 cost in its recipe YAML — then it becomes craftable.

☠️ Blighted Affixes

The spoils of your victory are imbued with devastating, game-changing enchantments:

⚔️ Weapons of Annihilation

| Affix | Effect | | :--- | :--- | | of the Serpent 🐍 | Infuses your strikes with a lethal, festering Poison that rots your enemies from the inside. | | of the Wraith 👻 | Channels the wrath of the dead, adding massive, soul-crushing Spirit damage. | | of the Blight ☢️ | An ultra-rare, god-tier enchantment combining both Poison and Spirit elements, while massively amplifying your weapon's base destruction. |

🛡️ Armor of the Titans

| Affix | Effect | | :--- | :--- | | of the Bastion 🏰 | Forges your armor into an impenetrable wall, granting a colossal boost to Armor Rating and unyielding Durability. | | of the Serpent 🐍 | Wards your flesh with absolute resistance against Venom and Poison. | | of the Wraith 👻 | Shields your soul, granting powerful resistance against necrotic Spirit attacks. | | of the Blight ☢️ | The ultimate ward. A phenomenally rare aegis that bestows both elemental resistances and a monstrous multiplier to your base armor rating. |


⚙️ Server Forging & Configuration

Bend the nightmare to your will via BepInEx config or Jotunn's Configuration Manager:

  • Boss Health & Sub-Boss Thresholds: Scale the Heart's vitality to create an insurmountable challenge in every biome. Sub-Boss HP is set per biome; their damage is one setting (Sub-Boss Level, each level above 1 adds +50%).
  • Wave Timers & Spawns: Dictate the pacing of the slaughter—adjust wave intervals and the maximum horde size allowed to swarm the battlefield.
  • Summoning Sacrifices: Demand greater tributes! Customize the specific items and quantities required to invoke the Heart in any territory.
  • Loot Scaling: Master the economy of war by adjusting the power curve of Blighted gear dropped across different biomes.
