Permadeath Mod v2.1.0 — The Hall of Flame & Modern Endgame Update

A massive expansion and structural overhaul for Permadeath (Fabric 1.21.1). This update completes the original vision conceived by ElRichMC, expanding survival progression beyond Day 70 all the way to Day 110 (The Hall of Flame), integrating native 1.21 mechanics, custom textures, and anti-cheese systems.

⚔️ Historical Expansion: Days 70 to 110

• Global 110-Day Cycle: MAX_DAYS extended to 110 days across 12 sequential progression phases.
• Phase 8 (Days 70–79) — The Abyssal Purge:
  • Sleep ban strictly enforced (bed interactions trigger warning explosions).
  • Cave Spider Stacks equipped with colored Shulkers and Instant Damage III Spawner Minecarts.
  • Deep Dark resonance below \(Y < 0\): unsneaked movement triggers Darkness and alerts nearby Wardens.
  • Native 1.21.1 Bogged integration with Weaving and Oozing status effects.
• Phase 9 (Days 80–89) — Supernova Storm:
  • Singularity Creepers generate localized gravitational pull fields upon ignition.
  • Overworld Supernova Breezes work in tandem with Creepers, firing wind charges to knock players into detonation radii.
  • Nether Bastion Praetorians (PiglinBrute) drop ancient debris, wind charges, and gold.
  • Telegraphed ionized lightning strikes with a 2-second ground spark warning.
  • Totem requirement increased to 4 per death (8% failure chance).
• Phase 10 (Days 90–99) — Dimensional Siege:
  • Void Endermen spawn with projectile immunity and telegraphed dimensional rifts (1.5s window). Sneaking cancels forced teleports.
  • Void Titans (Ancient Withers) and Void Wardens prowling outer End islands and The Beginning.
  • Accelerated void damage (\(Y < 0\)).
• Phase 11 (Days 100–109) — Twilight of the Gods:
  • Corrosive Acid Rain degrades armor durability and inflicts direct damage unless protected by the Infernal Netherite Helmet.
  • Twilight Giants roam the surface with an anti-pillar wind burst shockwave (GUST_EMITTER_LARGE) to counter vertical cheesing.
  • Ominous Champions packing multiple 1.21 combat modifiers (Wind Charged, Weaving, Oozing).
  • Totem requirement scaled to 5 per death (10% failure chance).
• Phase 12 (Day 110) — The Hall of Flame (Victory):
  • Global triumph announcement, challenge toast, and sleep restrictions lifted.
  • Exclusive Hall of Flame Medal: provides thermal damage immunity, passive Hero of the Village / Luck II, and divine totem revival buffs.

🏕️ Anti-Bunker & Survival Pressure System

• Habitat Stagnation System: Prevents indefinite underground camping. Remaining inside a 48-block radius for more than 20 minutes triggers progressive survival penalties (Metabolic Depletion, Armor Fragility, and Void Shadow Incursions).
• Active Countermeasures: Exploring outside base perimeters or slaying hostile mobs in expeditions relieves stagnation pressure.
• Fully configurable via permadeath_survival.properties.
• Added commands: /permadeath presion, /permadeath dias, and /permadeath info.

💎 Custom Expedition Rewards & Visual Overhaul

• 9 Hand-Crafted Pixel Art Textures (16x16) for custom functional expedition items:
  • Abyssal Antidote: Passive poison nullification.
  • Divine Peace Amulet: Passive Resistance when surrounded by hostiles.
  • Quantum Stability Vial: Prevents spatial distortion and purges levitation.
  • Abyssal Atmosphere Filter: Cleanses blindness, darkness, and mining fatigue.
  • Primordial Fire Talisman: Full fire and lava damage immunity.
  • Caustic Immunity Elixir: Drastically reduces indirect splash potion damage and purges Wither.
  • Inertial Gravity Anchor: Cancels Singularity Creeper pull and reduces wind knockback by 65%.
  • Dimensional Displacement Cloak: Emergency teleport safety fallback from the End void and 30% Sonic Boom damage reduction.
  • Acid-Proof Hermetic Coating: Full acid rain corrosion immunity.
• Custom sprites added for the Infernal Upgrade Smithing Template, Survivor Medal, and Hall of Flame Medal.

⚙️ Performance Optimizations & Engine Fixes

• Baseline Continuity Bridge (EndgameBaselineRules): Fixed phase transitions between Day 69 and 70 so Life Orb penalties, Infernal Netherite crafting, and relic constraints remain active through Day 109.
• Inventory Check Throttling: Reduced full-inventory iteration intervals for armor conversions and Life Orb scans (from every tick down to 10–20 ticks), heavily decreasing server CPU load.
• End Pillar Search Optimization: Replaced wide-range full-dimension block iteration with targeted annular scanning (\(r \in [34, 52]\)), eliminating multisecond tick freezes when loading The End.
• Attribute Scaling Safety: Bosses (Wither, Warden, Giant, EnderDragon) are excluded from additive global mob tier modifiers, preventing out-of-control multiplicative attribute bloat.
• Memory Leak Fixes: Event listeners now clean up cached player entries on disconnect and server stop.

📦 Installation & Compatibility

• Mod Loader: Fabric
• Target Minecraft Versions: 1.21.1
• Dependencies: Fabric API
• Works seamlessly on both single-player hardcore worlds and dedicated multiplayer servers.
