This is part of the quest " A Little Braver, and finding the Howl’s Fang isn’t too difficult. You can get the item early on, so long as you make a point to fetch it. If you’re having trouble locating it, the quick guide below tells you everything you need to know.
How to Find Howl’s Fang
Fight Howl, Get Double Jump
Past the Ori and the Will of the Wisps prologue, you’ll arrive in Inkwater Marsh. Your only option will be heading to your right, where you’ll eventually run into the great beast Howl, who will chase you to a campfire.
Pick up the torch and fight off Howl. From there, progress through the game until you find Spirit Edge and descend into the Howl’s Den section of the Marsh.
One of the two paths at the bottom of the chasm is blocked by a Keystone door, so head right until you reach a way down. Use the save point as a waypoint, and jump across to a long path leading left. Continue going left until you reach a Spirit Tree. Commune with it to receive Double Jump.
Backtrack for Howl’s Fang
Double Jump will allow you to head back toward the top of Inkwater Marsh. You’ll find a Moki named Mokk the Brave just to the right of the intersection where you ran from Howl. Speak to him to receive the “A Little Braver” quest, which asks you to find a Howl Fang.
Mokk will tell you he heard the howler fighting to the east, so make your way back to the Howl boss room to the right and use Double Jump to ascend past the arena.
You’ll come to an orange and green room with multiple hanging platforms and death vines on the floor. Jump across until you reach a set of branches holding up an item. This is Howl’s Fang. Run over it to place it in your inventory and head back to Mokk the Brave to complete the quest.
That’s everything you need to know about how to get Howl’s Fang early on in Ori and the Will of the Wisps. If you found this guide helpful, consider giving it a share!
