Biome Creature Speed Modifier

A quality-of-life mod for Valheim that lets you adjust movement speed and attack speed for every creature in the game — including bosses.

All settings default to vanilla behavior.

Non-boss creatures are grouped under ‘Creatures’ due to how Valheim defines spawn data.

Features

• Automatically registers all creatures
  • Vanilla creatures
  • Bosses
  • Future Valheim updates
  • Modded creatures (using standard Character prefabs)
• Per-creature movement speed sliders
• Per-creature attack speed sliders
• Real-time configuration via ConfigurationManager
• Vanilla-safe defaults (1.0)
• Singleplayer friendly

Configuration

This mod uses BepInEx ConfigurationManager (recommended).

Open the config UI

• Launch the game
• Press F1

Slider behavior

• 1.0 = Vanilla (default)
• < 1.0 = Slower
• > 1.0 = Faster

Attack speed controls how often a creature can attack
(higher values = shorter attack cooldowns).

Notes & Limitations

• Changes apply to newly spawned creatures only
• Existing creatures must despawn or respawn
• This mod affects movement speed and attack cooldowns only
• Very high attack speed values can be extremely dangerous, especially for bosses
