I can understand how you feel somewhat. Magic is part of Norse mythology. So for it to be included in Valheim is natural. I just think that some of the type of magic being added is well outside Norse Mythology. But then again the whole premise of Valheim, a 10th world, is outside of Norse beliefs. Them ain't Valkyrjur that drop you at your spawn point. And if Huginn is as annoying in real life as he is in the game, totally get why Odin sends him out to travel Midgard. The All-Father probably just wanted some peace and quiet.

So my approach to Valheim isn't one expecting adherence to what little we know about Norse Mythology and Beliefs, but more like Marvel's approach - very, very loose for mass appeal.

Do hope that you find a game to your liking. I know there are a few RPG's that stick close to reality in medieval times. Good luck.
