Balrond Monster Mayhem — BETA

Current development version: 1.2.0 Game: Valheim 1.0 Status: BETA — multiplayer, procedural miniboss runtime, optional AI assistance and newly authored assets still require dedicated-server/in-game verification.

Monster Mayhem is now an essential component of the Balrond Absolute Overhaul (BAO) experience. It is the creature, spawning, event, drop, taming and boss-combat module of the BAO mod suite. The BAO package also contains documentation covering Monster Mayhem and the larger mod-suite integration.

THIS MOD DOES NO LONGER WORK ON IT OWN AND REQUIRES Balrond Absolute Overhaul (BAO)

> Required dependencies: Balrond Absolute Overhaul and Balrond Humanoid Randomizer. Both are declared as hard BepInEx dependencies. Install compatible versions on the server and on participating clients. > > BETA notice: Back up worlds and characters before updating. Features involving new boss attacks, networked VFX, new spawns and world transitions may still have bugs. A successful source check is not a substitute for gameplay and dedicated-server testing.

What Monster Mayhem changes

Monster Mayhem expands Valheim's creatures and combat encounters while keeping separate ownership for BAO's world locations and item/content systems.

• Creatures and variants: additional animals, monsters, juveniles and dangerous biome encounters; new creature spawner prefabs and stat/resistance profiles.
• World spawns and events: a curated SpawnSystem overhaul, biome-specific encounters, raid/event changes and preservation of vanilla Deep North persistent-event gates.
• Boss fights: HP-gated authored attacks, Enrage effects, modest nearby-player scaling, disengaged regeneration and battle curses.
• Taming and breeding: vanilla-based taming, diet and feeding behavior, offspring, incubation, growth and creature-control stances.
• Minor Mutations: optional lightweight per-creature traits with synchronized ZDO state; two distinct forced mutations for promoted minibosses.
• Procedural minibosses (experimental, OFF by default): rare named versions of allowlisted wild creatures with extra native levels, boss UI and per-instance identity.
• AI navigation: conditional door/climb/ledge support, target hysteresis and obstruction targeting using native attacks.
• OdinHorse: conditional exclusions for the horse and offspring from BMM tame/movement adapters, without disabling BMM mount inventories on Lox and Asksvin.
• Multiplayer-first systems: server-synchronized gameplay configuration, owner-authoritative runtime changes and dedicated development diagnostics.

Creature item/prefab IDs and actual content availability depend on the matching Monster Mayhem and BAO assets. The _bal suffix is common in the Balrond suite and does not by itself prove that the object belongs to Monster Mayhem.

Installation and dependencies

1. Install Balrond Absolute Overhaul (BAO) and Balrond Humanoid Randomizer before Monster Mayhem. They are required dependencies, not optional recommendations.
2. Install Balrond Monster Mayhem 1.2.0 and its matching AssetBundle. Server and clients should use matching compatible mod versions.
3. Launch the game once to generate configuration files. For multiplayer, configure gameplay values on the host/dedicated server.
4. Test on a backed-up world. New worlds can generate new content naturally; existing explored areas may require world-upgrade procedures described in BAO's documentation. Monster Mayhem does not own Troll Cave / Bear Cave world-location edits.

Monster Mayhem does not replace Humanoid Randomizer: Humanoid Randomizer owns humanoid variants, variant equipment/attacks/animators and star-display presentation; Monster Mayhem owns creature gameplay rules, HP/resistances, final drop handling and its own boss attacks.

Configuration and ServerSync

Monster Mayhem now has a real configuration system. The earlier README statements that the mod has no config or ServerSync are obsolete.

Config file (BepInEx standard location):

BepInEx/config/balrond.astafaraios.BalrondMonsterMayhem.cfg

Gameplay configuration is synchronized through ServerSync. The server is authoritative when Lock Configuration is enabled (default: true). Debug/reporting controls are local developer settings and are not gameplay-authoritative.
