Raid and Monster spawning
From Midgard - Public Valheim Server Wiki
Mechanics
Light's protection counts as both spawn prevention and against your raid trigger threshold. Therefor you have two options.

- Illuminate your castle to keep the monsters from randomly spawning inside your base.
- Have a dimly lit castle and reduce the chance of raids but increase the chance of random spawns inside your base.
