History YMMV / Valheim

** Deathsquitos are arguably the most famous enemy for how many expeditions they have ruined. At only 10 hp even early game players can one-shot them quite easily. The catch is that Deathsquitos deal 90 damage a hit, fly and are among the fastest enemies in the game. Experienced players with the gear to bring down the damage to acceptable levels and a good shield tend to be fine, but players below the the silver age may find themselves in trouble. Deathsquitos have a large aggro range, can be difficult to see coming and have a habit of hanging out near the borders of other biomes, sometimes locking onto players still well into a neighbouring biome. Their ability to fly means they may also fly over water to harass any boat accidentally sailing too close to a plains coast. Deathsquitos ar so loathed it has spawned a multitude of memes and the developers even nerfed their initial damage output.

** Greydwarf Shamans are arguably the most dangerous enemy once the player gains access to the Black Forest, mainly due to their ability to poison the player. For many players it will be the first enemy encountered capable of doing so and chances are the player's food options are still very limited. They are also often accompanied by Greydwarves and can heal allied mobs.

** Greydwarf Shamans are arguably the most dangerous enemy once the player gains access to the Black Forest. They are often accompanied by Greydwarves, can heal allied mobs, and use various poison attacks that can quickly deplete your health.

** Depending on your progress in the game, archer enemies such as Skeletons and Draugrs can quickly become this. Their bows have very tight tracking and they are able to hit you from a long distance. Skeletons and draugrs are also often found in close proximity to each other. Running out of stamina with such an enemy tracking you quickly becomes lethal.

** Greyling Shamans are arguably the most dangerous enemy once the player gains access to the Black Forest. They are often accompanied by Greydwarves, can heal allied mobs, and use various poison attacks that can quickly deplete your health.

** The gas cloud attack of Blobs and Oozers are particularly nasty, as it's near instantaneous once executed and can't be blocked by any means. The poison inflicted by Oozers also has a high duration value.

** Nighttime in general. As night falls, a particular theme starts playing. Enemy spawn rates increase, including the chances to encounter the more powerful star versions of regular foes. Some biomes also feature dangerous night-exclusive enemies.

* Encountering Odin for the first time. He only appears at night, makes no movement or sound and simply stares at the player from a distance, dressed in his trademark black robes and with a single glowing eye.

* GuideDangIt: Figuring out how to obtain Sea Serpent scales without using a guide is quite an ordeal. If a serpent is slain on open water, its valuable scales will sink and can't be retrieved. In order to obtain them, the serpent must be defeated on land. How do you pull this off? Turns out you can craft a harpoon. However, the harpoon can't be made using stone, flint or metal. Instead, the player must venture out into the open sea to search for Leviathans, enormous yet benign creatures of which only the top of their stony carapaces are not submerged. The player must hop onto the island-like creature and use a pickaxe to mine the Abyssal Barnacles found there, which will yield Abyssal Chitin. With enough of this Chitin, a harpoon can then be made. Finally, the player can set out to find a sea serpent and harpoon it. Once you got one harpooned, you must make your way to the nearest coast all the while making sure the Serpent's struggles don't sink your boat first. Sail too fast, however, and your line breaks, resulting in the serpent swimming off. Once on land you must balance your stamina as you alternate between attacking the serpent and re-harpooning it. Quite often random mobs will come harass you as you drag your catch ashore. If you don't balance your stamina well, your line will break and the serpent slithers back into the ocean, fleeing immediately. Good luck, sailor!

** Boars in the meadows. They're also particularly fond of hit-and-run tactics. At the very least the resources they drop are useful.

* {{Squick}}: Sausages are made with meat and Draugr entrails.

* ThatOneSidequest: Finding Haldor the Merchant. For one, there is no indication in the game he even exists[[note]]Outside of the game, though, he appears in one of the screenshots on the game's Steam store page.[[/note]], and finding him is almost purely RNG, with the only limitation being that he's "somewhere" in the Black Forest. With good luck he might be near your starting area or the Elder altar, but with bad luck... let's just say there's a reason most guides tell you to just turn on cheats and fly around, or use a seed with his location already known.

* SugarWiki/AwesomeMusic: The background music can be considered one of the game's best points. Each boss and biome has its own personal background music to set the mood perfectly.

** Greyling Shamans are arguably the most dangerous enemy once the player gains access to the Dark Forest. They are often accompanied by Greydwarves, can heal allied mobs and use various poison attacks, which can quickly deplete one's health.

** Greydwarves are numerous in the Dark Forest biome and will often attempt to gang up on the player. Quite commonly they only serve to distract the player from a more powerful enemy, like a Shaman, Brute or Troll.

* {{Squick}}: I'm sorry the sausages are made from what now?
* ThatOneLevel: The swamp biome has all the ingredients that make swamp levels notorious. It is rife with [[DemonicSpiders dangerous enemies]] that can poison you, catch you off guard and deal a lot of damage. The area has low light even during the day and it often rains. The many puddles and gnarled trees hamper your movement and can obscure hostile creatures to boot.

* SpecialEffectsFailure: About the biggest complaint you will see for the game is that the graphics are very outdated, the game can make it work and look beautiful from a distances but one you get up close its hard not to notice the blocky shapes and basic texture mapping.
