Once Wendigo starts to run to you, try to dodge him but do not get hit If you dodge him successfully, he will stop. Go behind him and hit him once. Then, grab his tail by pressing Circle and swing him. Do this four times to defeat him.

Wait for him to stop chasing you, then run behind him. Hit him once or twice, then option for your special will appear. When you use your special, you will grab his tail. Spin him around and toss him. After several tosses, he will stand weak in the middle. Run up to him and use your special.
