World modifiers
Casual, Hardcore
or somewhere between.
Valheim's world modifiers change how hard the fight is, what death costs and what goes through portals. Pick a preset to see exactly what it sets.
- Normal
- Valheim as Iron Gate tuned it. Combat, death, resources, raids and portals all on their standard settings, and no metal through portals.
- Casual
- For exploring and building. You deal 25% more damage and enemies deal half; you keep what you're wearing when you die; resources drop 50% more; there are no raids, metal goes through portals and enemies leave you alone unless you start it.
- Easy
- A gentler fight. You deal 10% more damage, enemies deal 75% of normal, and raids come less often.
- Hard
- Enemies hit 50% harder and level up faster, you deal 15% less, and raids come more often.
- Hardcore
- Enemies deal double damage, death destroys everything you carry and resets your skills, there's no map, raids come more often and portals shut during boss fights.
- Immersive
- Standard combat, but no portals at all, no map and fire hazards on. You walk and sail everywhere.
- Hammer
- Building without the grind. Nothing costs materials to build, enemies are passive and there are no raids. The game counts it as a cheat for achievements.

Launch option-preset normal
These are the game's own preset values. A preset in the launch options rewrites the world's modifiers every time it starts, so if you upload a world you made on Casual, set Casual here too. Some modifiers turn achievements off.
