The Draugr Fang is possibly one of the best bows you can get in Valheim due to it’s insane damage numbers AND applicable poison damage. It’s not the easiest bow to grind out the resources for, but if you’re willing to venture deep into the swamps, and mine silver high up on the mountain tops, you’ll get yourself quite the powerful weapon.
Oh, and it looks friggin awesome, I’d use it even if it dealt absolute crap damage just cause it looks cool.
