PassiveMobs

A BepInEx mod for Valheim 1.0 with three independent features (all 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.

   • SkittishCreatures run away from a player who stays within SkittishRange for SkittishTime seconds.
   • TerritorialCreatures attack a player who stays within TerritorialRange for TerritorialTime seconds, then run away for TerritorialRetreatTime seconds.

2. Enemies fear strong players: non-passive enemies run away from players whose gear outclasses it, instead of attacking. An enemy you attack stops running and fights back until FightBackDuration seconds after your last hit. Raid creatures never run away.

3. Neutral creatures: the Dvergr and other creatures that are friendly until angered only turn hostile after HitsToAnger (default 2) hits from a player within AngerWindow seconds, instead of on the first stray hit. Once angry, they make peace again CalmDownTime seconds (default 5 minutes) after the fighting stops.

Requires Jötunn.

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

Required on the server and every client. Settings are synced from the server to the clients. Config changes are synced live.

Building

dotnet build -c Release

The game path comes from the Steam registry keys. The build copies TruePassiveMobs.dll to BepInEx/plugins/TruePassiveMobs/; pass -p:DeployToGame=false to skip that step.

To override the paths, create a gitignored Environment.props next to the csproj. With a mod manager, point BepInExPath at the profile's BepInEx folder and DeployDir at the mod's folder in it:

<Project>
  <PropertyGroup>
    <BepInExPath>$(APPDATA)\r2modmanPlus-local\Valheim\profiles\MyProfile\BepInEx</BepInExPath>
    <DeployDir>$(BepInExPath)\plugins\lhoffl-TruePassiveMobs</DeployDir>
  </PropertyGroup>
</Project>
