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.
