Balrond Monster Mayhem — Changelog

Latest first | Current BETA: 1.1.36 (FIX15)

Monster Mayhem is now an essential part of the Balrond Absolute Overhaul ecosystem. It has hard dependencies on Balrond Absolute Overhaul and Balrond Humanoid Randomizer. The BAO distribution also contains documentation for Monster Mayhem. This is a BETA build and requires runtime testing, especially for new boss attacks and multiplayer VFX.

1.1.36 — BETA: Boss phases, content registration and stabilization (through FIX15)

Boss encounters and Enrage

• Reworked HP-phase progression: 75% HP unlocks the first new attack and gives a 6-second Enrage; 50% HP unlocks additional authored attacks and repeats 6-second Enrage; 25% HP starts permanent Enrage.
• Introduced startup-registered SE_BMM_BossEnrageBurst and SE_BMM_BossEnrage. Both use the authored vfx_bmm_boss_enrage via StatusEffect.m_startEffects and follow/scale with the boss; no mid-fight status registration is intended.
• Default Enrage damage bonus: +10%, synchronized; temporary and permanent bonuses do not stack. The final phase announces “Boss is now angry” to nearby participants.
• Corrected Bonemass order: Globules at 75%, Sludge Fields at 50%.
• Added authored boss attack registries and guarded assignment to boss Humanoid attack lists, respecting Valheim's native health-range AI gates. Missing assets are skipped instead of substituted.
• Disabled pending assets: BMM_Moder_GlacialStormColumns_Attack, BMM_Bonemass_DecayAura_Attack, BMM_SeekerQueen_AcidGround_Attack, BMM_Fader_SoulfirePressure_Attack. Fader gains no new authored attack until its asset is supplied.
• Added host-only mm_boss_test for enabling a selected new attack without its HP gate for AI testing; normal target, animation, range and cooldown conditions remain active.

Registration and multiplayer safeguards

• Hardened ObjectDB / ZNetScene lifecycle, item/prefab identity checks and re-registration after ObjectDB.CopyOtherDB; avoided replacing other mods' prefab instances on name collisions.
• Added a registry for authored custom monster status assets (including SE_Elder_heal_bal) and made their registration part of the startup lifecycle.
• Updated boss phase/Enrage state synchronization using owner-written ZDO data and safeguards against duplicate application; reinforced related RPC validation and ownership checks in creature systems.
• Excluded the FrozenKing phase-prefab chain from Minor Mutations, without disabling progression-based boss mutations for other bosses.
• Added diagnostics for missing or incompatible boss assets. Newly authored special attack behavior and multiplayer visual timing still require runtime verification.

World spawns, monsters and loot

• Improved world-reload handling of spawn rules and reduced duplicate/ambiguous SpawnData warnings, while retaining Golden Master/native row identity and persistent-event gates.
• Corrected Troll and other CharacterDrop parity handling: disabled unwanted drops without removing native rows, and resolved conflicting Troll drop overrides.
• Added the TrollMother_bal supplemental rare Mountains spawn and drop configuration. Its Heart remains an optional BAO asset dependency; the future Trophy is not an active drop until authored.
• Retained Deep North persistent-event safety and the separation between native AltBiome/PersistentEvent data and Monster Mayhem's global spawn rules.

Performance, diagnostics and project maintenance

• Reduced redundant player-list refreshes, tame-AI component checks, hunger/ownership checks and repeated spawn-list lookups in identified hot paths.
• Consolidated normal logging into short startup/status summaries; detailed AltBiome, Deep North, spawn, creature and boss audit output belongs to developer Debug/Verbose mode. Real warnings and errors remain visible.
• Preserved developer diagnostics, console commands and regression tests while removing 62 obsolete project artifacts (historical reports, patch notes, inactive legacy sources and stale DLLs) through the FIX15 cleanup manifest.
• Updated the project configuration and documentation for ServerSync, BAO ownership and the required Humanoid Randomizer integration.

Verification note: Static source and regression tests reported PASS for FIX15. This is not a claim that a Release DLL, boss VFX, new attack behavior or dedicated-server multiplayer has passed an in-game test.

Previous 1.1.x development milestones

• Added owner-authoritative per-instance natural mutations stored in ZDO: Robust, Ferocious, Swift and Resistant.
