I'd wager that most Soulsborne players have, at one time or other, ventured into a new area before being torn to shreds by an overpowered enemy. Me? I've never had my Hollow Warrior Helm handed to me quicker than during my first encounter with New Londo's Darkwraiths. These bastards are the latest class to be modded into Darkest Dungeon.
