Valheim Wiki

Bosses are unique creatures found throughout Valheim. They possess high volumes of health and output large numbers of damage respective to their biome location.


Main article: Eikthyr

Eikthyr is the first boss and is found in Meadows.

The fight against Eikthyr is not particularly difficult and serves to test the player's understanding of the basic game mechanics. Players may want to be rested for the fight and have the best food, armor and weapon available. Eikthyr has no resistances to any damage type, so the player can use their preferred weapon.

All of Eikthyr's attacks can be blocked with a Wood shield. Hitting Eikthyr in-between his attacks allows the player to whittle him down in under three minutes.

An easy way to deal with this boss is to use a bow. You can keep your distance and run around the big rocks of the altar while shooting him. The rocks will keep you safe from his forward charge however his AoE lightning discharge will still reach you if you are close to him.

The Elder

Main article: The Elder

The Elder is the second boss after Eikthyr and is found in Black Forests.

He has a total of 2500 HP, with neutral resistances to most damage types, but is weak to Fire. As with all boss fights, the player will have the greatest odds of success when equipped with the strongest armor and weapons available (such as bronze equipment) and consuming the best available food.

Dealing with attacks

Vine shoot

The four pillars around the altar are indestructible and can be hidden behind for cover. The Elder will not use this attack against a player in melee range.


Can be blocked, ran away from, or avoided with the brief invincibility of rolling. A solo player with a fully upgraded Bronze Buckler can fully block most stomps without being staggered. Parrying or having a block skill of 18 means the player will never be staggered. This is not the case when playing in a group, as enemies deal 4% more damage per extra player in the area.

Spawn roots

Running away from summoned Roots may be preferable to attacking them. They will despawn after a short while.

Other strategies and notes

  • Ranged attacks with a bow can be a safer and simpler strategy than melee. The best bow typically available at this phase of the game is the Finewood bow and fire arrows are the most effective arrows. For a solo player, 200 fire arrows may be necessary, but the exact amount depends on bow skill.
  • Use of Eikthyr Power can be desirable to reduce stamina drain from running.
  • The entire area under the altar platform can be excavated, with the altar platform forming a sturdy roof to a large underground chamber. There's enough room for a fully equipped base down there, with a workbench, forge, and portal, beyond the reach of the Elder and any other enemy, for that matter.

Group strategies

  • Splitting up so his ranged vine attacks only target one individual will allow other players to focus on attacking him, rather than running from his attacks.
  • The Elder typically targets the player closest to him, so designating one player as the "tank" or even cycling this designated player may help the group manage the fight.
  • Multiple players attacking The Elder with melee weapons can deal high amounts of damage in return for a higher level of danger to the stomp attack.
  • Fire damage from multiple players do not stack separately per player. i.e. enemies can only be affected by a single fire effect at a time.


Main article: Bonemass

Bonemass is the third boss after The Elder and is found in Swamps.

Dealing with its attacks

  • The fight is balanced around the expectation that players will use Poison resistance mead which reduces poison damage by 75%. Not doing so can be very dangerous, and would require prior experience with the fight to avoid being poisoned.
  • Summon minions: If the minions are not prioritized they may overwhelm the player. Bonemass' armpit glob summon is generally aimed away from players and has a very slow animation, during which it is vulnerable to attack. Alternatively the player may prefer to back up and prepare to attack the spawned creatures the moment they land. The Stagbreaker and Iron sledge are very effective for this.
  • Poison Cloud: To completely avoid this attack, players in melee range may need to start running away immediately when it looks like Bonemass is about to sneeze. Rolling can be too slow and drains more stamina than running.
  • Melee: Very strong and poison-inflicting, normal blocking will likely stagger the player and inflict the leftover damage. Can be parried, or dodged using the brief invincibility of rolling. It can also be avoided by sprinting out of range.

Damage types

  • Bonemass and its minions are weak to blunt damage and resistant to almost everything else. Players wanting as short of a fight as possible will want to use clubs.
    • Frostner is the ideal weapon for fighting Bonemass due it dealing both blunt and frost damage. It is theoretically possible to craft it prior to fighting Bonemass but finding the required silver is extremely difficult without the Wishbone.
  • Pierce damage (including bows) is extremely ineffective. Of the available arrows, Frost arrows are somewhat effective, but requires mountain exploration to gather the required Obsidian and Frost glands from Drakes.

Other strategies and notes

  • Using a hoe to level out and/or raise the area around the summoning altar will serve the dual purpose of allowing better mobility for the player during the fight and also preventing leeches from interfering with the fight.
  • Having multiple Medium healing mead and high health Food may be desirable.
  • Use of Eikthyr Power can be desirable to reduce stamina drain from running and jumping.
  • Crafting a hundred or so frost arrows and shooting Bonemass from up high in the trees is a safe and easy way of defeating Bonemass. Some spawn locations may have a large stone tower that can be accessed as well.
  • Bonemass may be easily defeated using Poison Resistance Mead and a two-handed club, such as the Iron Sledge. By first summoning the boss, then climbing atop its altar from the rear, the player can take advantage of the large area of effect of some weapons to deal damage to Bonemass whilst knocking any spawned enemies off of the alter from knockback, and remaining out of range of any of its attacks. The player is still likely to get poisoned, so Poison Resistance Mead is necessary.

Group strategies

It may be ideal to have most players focused on killing the skeleton and blob spawns as soon as they land. While there is a cap on how many minions Bonemass can have spawned at once, it is very high at 8 Skeletons and 8 Blobs.

If the group is 3 or more players with a preference for bows, a ranged strategy can still work even without frost arrows. Despite the boss's resistances, the groups constant, combined damage can whittle it down fairly quickly. Players should spread out from each other so that only the one player Bonemass is currently chasing needs to run away. Minions should be focused as soon as they spawn, ideally switching to blunt melee damage to kill them quickly, and then swap back to bows for Bonemass.


Main article: Moder

Moder is the fourth boss after Bonemass and is found in Mountains.

Unlike the previous Bonemass fight, this fight can be done without top-tier armor as all of Moder's attacks are much easier to avoid. Provided the player keeps their distance from her, it is possible to complete the fight without taking damage. Her barrage can be avoided by running, rolling, blocking, or using the terrain. Building a pillar by raising the terrain with a hoe makes for effective cover to hide behind. Beware that her attacks will destroy naturally spawned rocks and trees due to the chop and pickaxe damage.

Players should consider the possibility of their weapons breaking, and have either a forge or a portal nearby. Beware that Moder can choose to attack exposed major structures if she sees them, but will not specifically attack walls and roofing. Starting the fight late in the day can make the fight a lot harder than it needs to be, because at night dangerous creatures such as starred Wolves or Fenrings may join the fight.


Because of her size, Moder can't navigate through rough terrain very well, making her vulnerable to ranged attacks during her grounded phase. If she doesn't see a flat path to approach a player then she won't move much until she decides to go airborne again. This leaves her very vulnerable to arrows and makes the fight especially simple for a single player when compared to Bonemass and the swarm of Blobs.

Arrow effectiveness

Arrow effectiveness is typically in the order of Needle > Obsidian > Fire > Poison. Moder's only weakness is to fire, but Fire arrows still do slightly less damage than Obsidian arrows. However fire arrows can be easier to craft.

Poison arrows can potentially do high damage but most of the damage is usually wasted because reapplying the poison doesn't stack the damage. Players in a group should make sure that only a single player is using them. Poison arrows can still be useful when mixed with other arrows which gives the poison more time to expire. However there isn't any reason to craft them as they are more expensive than obsidian arrows.


With Bonemass Power activated or with fully-upgraded wolf armor, fighting in melee range is viable, and melee attacks with silver-tier weapons do significantly more damage than arrows. Additionally, blocking with a silver shield will mitigate most of the damage from Moder's melee attacks. For quick health recovery, the player can consume a medium healing mead. A bow is essential for doing damage while Moder is flying.


Main article: Yagluth

Yagluth is the fifth boss after Moder and is found in Plains.

Attacks and abilities

  • The fight is balanced around the expectation that players will use Fire resistance barley wine which reduces fire damage by up to 75%. Not doing so can be very dangerous. Armor further reduces fire damage.
  • Meteors: They can be outrun, or the stone pillars can be used as cover. If melee'ing Yagluth, remaining in front of his face is an option, as his head will block most of the meteors.
  • Nova: Can be dodged using the brief invincibility of rolling as Yagluth slam's his fist down.
  • Fire Breath: Yagluth only uses this attack against a player not in melee range. It can be avoided by moving in either side direction. The stone pillars can be used as cover, although they will take damage and eventually break from repeated attacks. It can also be blocked with a shield, but this is not an effective strategy as it will rapidly drain the players stamina.

Melee strategies

Trying to avoid taking damage entirely can make for a very long fight, as Yagluth doesn't provide many openings. With Bonemass Power, good Food and reasonable armor, his attacks can be ignored for quite a while before getting low on health. Otherwise it may be preferable to dodge-roll his Nova, as it deals up to 130 raw blunt damage.

Other strategies

  • Frost arrows are the best arrow type for dealing damage to Yagluth.
  • It is possible to hit freely and backstab Yagluth while he is raising from the ground (starting animation).
  • Yagluth takes spirit damage, making the Silver sword and Frostner decent weapon choices against him. Raw damage of Blackmetal sword also works.
  • A tunnel can be dug under his altar to provide a safe place to regenerate health and repair weapons or portal out. A campfire can be built for the resting bonus.
  • Yagluth will not cast Fire Breath and Meteors when his target is beyond a certain range. Players can hit him with arrows whilst standing in this "safe" spot.
  • Yagluth only becomes Wet when completely submerged which means trying to make him a Frost weakness is not practical.
