Vordt of the Boreal Valley
Once you’ve made your way through the High Wall of Lothric, you’ll come to an opening where you’re greeted by Vordt of the Boreal Valley. Vordt’s not a particularly difficult fight, though his bulk combined with his high speed later on in the fight can seem intimidating.
Once again, like with Iudex Gundyr, rolling is recommended here. Vordt will often try and attack you with his mace, but the thing about this boss is that all of his attacks come from the front. If you hug his rear and attack him, he can’t hit you.
