Few challenges in Valheim compare to facing Moder, the dragon of the Mountains biome. As the fourth Forsaken boss, Moder Valheim is a powerful, majestic, and dangerous foe that tests your survival skills, archery accuracy, and frost resistance.
In this detailed guide, we’ll walk you through everything you need to know: how to find Moder Valheim, how to prepare, how to summon Moder Valheim, her strengths and weaknesses, and the best way to beat Moder Valheim without rage-quitting.
Let’s head into the snowy peaks and prepare for battle.
Who Is Moder in Valheim?
Moder is the fourth boss you must defeat in Valheim’s progression path. She represents the Mountain biome and takes the form of a massive, black-and-blue frost dragon. Once summoned, she alternates between flying frost breath attacks and ground-based melee swipes.
Defeating her is crucial for unlocking new tools and access to the final biome progression in the game. But unlike previous bosses, this one takes serious preparation.
How to Find Moder Valheim
You won’t stumble upon Moder easily—she’s hidden deep in the Mountains biome.
Steps to Locate Moder:
- Head to a Mountain biome (be sure to bring frost resistance mead).
- Explore until you find a Runestone that reveals Moder’s altar location.
- Use the Runestone (a small stone tablet near stone structures) to ping her summoning point on your map.
Tip: You’ll need a Wishbone (from Bonemass) to find the Runestone faster.
Sometimes, the altar may appear far from your starting base, so prepare for a long and cold journey.
How to Summon Moder Valheim
Once you reach her altar, you’ll need special items to summon her.
Required Items:
- 3 Dragon Eggs (each weighing 200 units)
You’ll find Dragon Eggs in Mountain biomes inside drake nests. Use a pickaxe to extract them.
Pro Tips:
- You’ll likely need portals for back-and-forth transport—Dragon Eggs are heavy and can’t be teleported.
- Consider building a summoning base nearby for prep and respawn.
Place all three Dragon Eggs into the altar and interact to start the fight. Make sure you’re geared up—there’s no turning back.
Moder Valheim Weakness
Moder is a frost dragon, so unsurprisingly, her main weakness is fire.
Attack Weakness Breakdown:
- Weak to Fire Damage ✅
- Resistant to Frost ❌
- Immune to Spirit ❌
To maximize your damage output:
- Use fire arrows or needle arrows (more on this below).
- Avoid frost damage weapons or frost magic from mods—they’re useless here.
Best Arrows for Moder Valheim
Your choice of arrows can make or break the fight.
Ranked List of Arrows (Best to Worst):
- Needle Arrows: Highest base damage; excellent if combined with high bow skill.
- Fire Arrows: Direct elemental weakness; consistent burn effect.

- Use terrain creatively.
- Bring a Shield as backup if she corners you.
Multiplayer Strategy:

Dragon Tears are essential for:

Dragon Tear Crafting After Moder

What You Can Build with Dragon Tears:
