The bosses in Valheim are as unforgiving as the game itself, and Moder leads the pack as one of the most intimidating fights and summoning rituals.

Here’s where to find Moder's summoning altar, and how to survive fighting her.

How to Summon Moder in Valheim

Moder is a fearsome flying dragon in Valheim found in the Mountain biome, which is a tricky one to navigate due to the weather. Once you’re equipped to travel in the Mountain biome, you can begin searching for one of multiple Moder summoning altars.

To guarantee the location of a Moder summoning altar, you can find and interact with a Vegvisir Runestone in the Mountain biome. Doing so places a pin on your map, telling you the exact location of this boss.

Once you’ve found the altar, you’ll have to find and transport 3x Dragon Egg to it. This is a very time-consuming task, as Dragon Eggs are incredibly heavy, and, like ore, can’t be transported via teleporter. Playing with two or more friends in a Valheim server helps simplify this objective while ensuring you stay protected from hostiles.

With the three eggs in their rightful places, interact with the altar to start the boss fight.

How to Defeat Moder

Moder is a challenging boss fight, and like conquering other bosses in Valheim, you’ll have to be prepared.

Unlike the previous bosses that stay grounded, Moder will spend periods of her fight flying through the air and firing ice down to the ground. After this fly-around period, she’ll land on the ground, and you’ll have a new set of attacks to deal with.

While on the ground, Moder will swipe in a big area in front of her, or shoot out frost breath in a cone. All of Moder’s attacks slow players significantly. That means it's important to minimize damage, as it can quickly spiral out of control.

The key to killing Moder in Valheim is utilizing the terrain around you. Moder has a hard time navigating clutter, and taking cover during her ranged barrages can ensure you’re safe without having to dodge.

To deal damage to Moder, make sure you are prepared to use your bow for a long period of time. That means you’ll need plenty of arrows and repairs. While you’ll be able to continue shooting Moder during her landing, this also opens her up to melee attacks if you can time it.

Remember, Moder is weak to Fire but immune to Frost. So, use the appropriate elements against her. Rinse and repeat these attacks. Avoid Moder’s moves, and you’ll clean her up, moving on with your Valheim progression.

Below are some additional tips and tricks to help you permanently clip the wings off of this dragon:

• Equip the Wolf Armor and increase Frost resistance. The Mountain biome’s freezing environment remains dangerous during the battle. This armor set, along with the Frost Resistance Mead, helps reduce the risks of falling to Mother Nature while fighting Moder.
• Bring melee and ranged weapons. The Silver Sword is an excellent melee weapon at this point in the game. As for ranged choices, equip your best bow and fire Needle and Obsidian Arrows at Moder to increase DPS while she’s flying.
• Control the fight as much as possible. Some players make the mistake of treating the Moder boss fight as a damage race. Instead, pace yourself and spend stamina only on dodging. Always staying on the offensive can turn the tide of battle to the boss’s favor, so be warned.

Moder Loot & Rewards

Defeating Eikthyr, The Elder, and Bonemass typically grants Forsaken Powers to help players reduce some of Valheim’s growing pains, such as fast stamina depletion. On the other hand, besting this dragon boss rewards you with the Moder Trophy. Placing and interacting with it grants the Moder’s Forsaken Power for 300 seconds, which includes the following benefits:

• +300 to Maximum Carry Weight
• Increases Resistance versus Frost
• +10% Movement Speed

Aside from this unique power, winning the Moder boss fight also rewards you with 10x Dragon Tear. Use 2x Dragon Tear and 10x Wood to craft the Artisan Table, a workstation that allows you to build structures like the Blast Furnace, Stone Oven, and Spinning Wheel.
