What Does the Crown of Roots Do in Valheim?

The Crown of Roots is a wearable headpiece in Valheim that players can buy from the Bog Witch, a friendly NPC found in Swamp biomes who sells a variety of cooking and potion-making ingredients. However, before the Bog Witch starts selling the Crown of Roots, you'll first need to defeat a Writhan, a freaky-looking bog creature that can also be found in swamps. There's a bit more to this than just monster hunting and shopping, though, so if you want this headpiece in Valheim, you'll need to know the intricacies behind it.
