PassiveMobs

A BepInEx mod for Valheim 1.0 with two independent features (both on by default):

1. Passive creatures: By default Lox, Asksvin, Moose, Boar, Hen, Neck, and Bjorn leave players alone until a player damages them. After that they fight back as normal for ProvokedDuration seconds after the last hit, then calm down again.
2. Enemies fear strong players: non-passive enemies run away from players whose gear outclasses it, instead of attacking.

How "outclassed" is decided

The mod uses two checks, each can be turned on or off:

Check	Passes when
UseEnemyDamageCheck	The enemy's strongest attack, after your armor and resistances, deals at most MaxEnemyHitPercent (default 10%) of your max health.
UsePlayerDamageCheck	Your equipped weapon kills the enemy in at most MaxHitsToKill (default 3) average hits. This includes your skill, active buffs and the enemy's resistances.

The math uses the game's own formulas, including star level, world difficulty settings, player-count scaling and world level. These are rough outcomes with the defaults, using 3★ gear and typical food:

Your gear	Runs away	Still fights
Iron	Greydwarves, greydwarf brutes, skeletons	Trolls, draugr, wolves
Padded + Blackmetal	Everything above, plus draugr and wolves	Fenrings, goblins, trolls
Carapace + Mistwalker	Everything above, plus fenrings and goblins	Goblin brutes, seeker soldiers

Config

The config file is BepInEx/config/com.lhoffl.TruePassiveMobs.cfg. It reloads automatically when you save it, so you can tune it while the game runs.

Multiplayer

Creatures are simulated by whichever client owns them, so every player needs the mod. Each client publishes its own player's armor, resistances and weapon damage, so enemies judge every player by that player's real gear. Players without the mod are never feared. The config isn't synced, so everyone should use the same settings.

Building

dotnet build -c Release

The game path comes from the Steam registry keys. To override it, pass -p:GamePath=... or create Environment.props; the top of TruePassiveMobs.csproj shows how. The build copies TruePassiveMobs.dll to BepInEx/plugins/TruePassiveMobs/. Pass -p:DeployToGame=false to skip that step.
