🌑 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 200+ incredibly rare, unique Blighted variations of Vanilla weapons and armors, forged in the heat of battle!
• 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.

☠️ Blighted Affixes

🟢 [1.0.7]

🛠️ Fixed

• Crafting List Blank Page Conflict: Completely resolved a critical incompatibility with AzuAntiArthriticCrafting (and other UI overhaul mods) where opening a crafting station without materials would result in a completely empty recipe list. The root cause was that BWH's recipe filtering occurred too late in the rendering pipeline, causing UI paginators to draw empty pages. The filtering has been relocated to run at the engine level, seamlessly integrating with third-party pagination and sorting.
• AAACrafting / No-Cost Mode Compatibility: Admins and testers with the nocost cheat active (or AAACrafting's no-cost mode) can now successfully preview and spawn every Blighted recipe in the Craft tab. Previously, the hiding logic ignored no-cost state.
• WackyDB Compatibility Gap: WackyDB installs now correctly bypass BWH's internal UI hiding logic, handing full control to server admins via YAML, as originally intended.
• Recipe Validation Pass: Added a strict post-initialization validation sweep that scans all injected custom items for corrupted or missing data (like a null m_dlc field), repairing them instantly to prevent vanilla Valheim from throwing exceptions during recipe enumeration.
• Recipe Resolution Reliability: Vanilla-material injection for Blighted upgrade recipes now retries on subsequent player spawns if ObjectDB is delayed during initial world load, preventing permanent recipe breakage in heavily modded multiplayer servers.
• Deep North Wave/Sub-Boss Fallback: Fixed an issue where the Blighted World Heart spawned in the Deep North would silently fall back to spawning trivial Boars. It now correctly falls back to Mountain-tier enemies and bosses, matching the fallback loot table for the biome.

⚖️ Changed

• Magical Damage Mitigation: Added a new configuration option Magic Damage Multiplier (default 0.25). Magic and elemental damage from late-game magical weapons is now calculated separately and heavily reduced against the Blighted World Heart and its Sub-Bosses, ensuring they can withstand arcane assaults and don't get instantly obliterated by staves.
• Boss Vitality Boost: Increased the default HP configuration values for the main Blighted World Heart and all Sub-Bosses by 15% across all biomes to compensate for high-tier player damage.
• Configuration Overhaul: Rewrote the internal configuration descriptors to be much clearer on exactly what each setting does. Also added strict minimum and maximum acceptable value ranges to all numerical configurations to prevent accidental typos from breaking the mod.

🟢 [1.0.6]

✨ Added

• Wacky's Database Compatibility Mode: Added seamless, automatic integration with Wacky's Database. Upon startup, if Wacky's Database is detected, BlightedWorldHeart will automatically bypass its internal dynamic recipe modifications and UI hiding logic. This hands over total, unadulterated control to server admins and players who wish to customize Blighted weapon/armor stats and recipes using WackyDB's YAML files, safely preventing any recipe injection conflicts or crashes.

⬆️ Updated

• Dependencies: Updated Jotunn dependency to v2.29.1.

🟢 [1.0.5]

🛠️ Fixed

• Multiplayer Sync: Fixed a multiplayer synchronization issue where players other than the summoner could not see the SubBoss health bars, and the main Heart health bar did not update for them.
• Localization: Fixed an issue where SubBoss names would sometimes display their unlocalized internal names (e.g. $enemy_troll) on client UI. The UI now dynamically localizes all names for everyone.

🟢 [1.0.4]

🔄 Changed

• Blighted Item Upgrades & Repairs Fixed: Blighted weapons and armors can now be properly upgraded and repaired by all players. We completely reworked how the recipes are handled under the hood so they no longer require admin privileges or "nocost" to function.
• Dynamic Upgrade Costs: Upgrading a Blighted item now requires the same base materials as its vanilla counterpart, plus the biome-specific trophies. They remain entirely uncraftable.
  • Example: Upgrading a "Blighted Sword Iron of the Serpent" from Level 1 to Level 2 will cost 20 Iron, 3 Wood, 2 Draugr Trophies, and 2 Leech Trophies (using the base Iron Sword upgrade cost plus Swamp trophies).

🟢 [1.0.3]

• 🧪 Internal testing build

🟢 [1.0.2]

• 🩹 Accidently updated v1.0.0 as v1.0.1; this package labelled v1.0.2 is the corrected version

🟢 [1.0.1]

⚖️ Changed

• Weapon Rebalancing: Significantly reduced the overall damage scaling and flat elemental damage (Poison/Spirit) bonuses on Blighted weapons to bring them back in line with vanilla progression curves.
• Shield Categorization: Fixed an issue where custom shields were incorrectly categorized as weapons. Shields now properly receive the Bastion/Blight defensive armor modifiers instead of weapon damage bonuses.
• Swamp Boss Altar Spawn: Adjusted the spawn logic for the Blighted World Heart when summoned in the Swamp biome. The Heart will now properly offset outward from the altar and drop to the ground, preventing it from spawning out of reach on top of the giant skull roof or getting stuck inside.

🛠️ Fixed

• Custom Item Repairs: Fixed an issue where Blighted custom items (weapons and armors) could not be repaired at normal crafting stations. They now properly tie into the Workbench, Forge, and Black Forge for standard, cost-free repairing.
• Damage Filtering Fix (Invulnerability): Fixed a major oversight where the Blighted World Heart could still be damaged by generic non-player environmental attacks (such as Troll AoE log swings and Abomination body slams). The damage filtering logic has been strictly enforced directly into the Heart's core damage receiver to block all non-player entity damage.
• Tamed Minion Exception: Added an explicit exception to the new damage filter allowing players and their tamed or summoned creatures (e.g., wolves, lox, Dead Raiser skeletons) to successfully damage the Heart.
