How do you find and defeat Moder in the Mountains biome?

Defeating Moder, the dragon boss of the Mountains biome in Valheim, is a challenging but rewarding task. To begin, you must first locate Moder''s summoning altar. This requires finding a Vegvisir runestone in the Mountains biome, which will mark the altar''s location on your map. Moder''s altar is typically found in high-altitude areas, so prepare for a steep climb and cold weather. Before attempting to summon Moder, ensure you are well-equipped with frost-resistant gear, powerful weapons, and ample supplies.\n\nTo survive the cold in the Mountains biome, you need frost resistance. This can be achieved by crafting a Wolf Fur Cape or Lox Cape, both of which require materials from the Mountains biome. Alternatively, you can drink Frost Resistance Mead, crafted at a Fermenter using Honey, Thistle, Bloodbag, and Greydwarf Eye. Without frost resistance, you will take constant damage from the cold, making the fight nearly impossible. Additionally, bring a Campfire or Portal materials to set up a safe base near the altar for respawns and rest.\n\nOnce you are prepared, summon Moder by placing three Dragon Eggs at her altar. Dragon Eggs are heavy and require significant stamina to carry, so plan your route carefully. You may need to make multiple trips or use a Cart to transport them. Moder is a formidable opponent with powerful ranged and melee attacks, including ice breath and claw swipes. She can also summon ice shards from the ground, so stay mobile and avoid standing in one place for too long.\n\nFor the fight, bring a Draugr Fang bow with plenty of Poison or Needle Arrows, as ranged combat is highly effective against Moder. Melee weapons like the Blackmetal Sword or Frostner can also be useful, but be cautious of her close-range attacks. Use the terrain to your advantage by hiding behind rocks or trees to avoid her ice breath. If you have a shield, blocking her claw swipes can save you from significant damage. Always keep an eye on your stamina and health, and use healing meads like Medium Healing Mead or Tasty Mead to stay alive.\n\nAfter defeating Moder, you will receive her trophy and Dragon Tears. The trophy can be placed at the Forsaken Altar to unlock her power, which grants a strong tailwind when sailing, making ocean travel much faster. Dragon Tears are essential for crafting the Artisan Table, which unlocks advanced crafting options like the Blast Furnace and Windmill. These tools are crucial for progressing to the Plains biome and beyond.\n\nPractical tips for this fight include bringing a fully upgraded set of Wolf Armor for maximum protection and frost resistance. Always have a backup plan, such as a Portal nearby, in case you need to retreat and restock. If you are struggling with the fight, consider bringing a friend or two, as Moder''s health scales with the number of players. Finally, practice patience and persistence, as Moder is one of the toughest bosses in Valheim but also one of the most rewarding to defeat.
