Look For Alternate Routes and Shortcuts
Just like the Dark Souls III base game, Ashes of Ariandel plays around a lot with verticality as well. Each time you enter a new area or a new building, chances are, there’s likely going to be an upper level or area that you can get to. Not only that, sometimes these areas might house shortcuts that lead you back to the nearest bonfire. You might also be able to find new paths that allow you to flank enemies.
If you happen to come up against a really tough enemy, or a group of enemies that seem impossible to beat, try looking around for other areas you can go to. You just might find a new vantage point or positioning that allows you to backstab them or bypass that mob altogether. You can always come back to them once you’ve gotten a little stronger. The areas are very interconnected, and most of them are winded around each other. Keep exploring different paths to find different ways of progression.
