Draugr Fiends are essentially stronger versions of Draugr Butchers. The only key difference is that Fiends can envelop themselves in flame after performing a combo, and striking them makes them explode, blowing Kratos backwards. When one's ignited, try not to show some restraint, and hit them with a ranged attack to get rid of their fiery aura.
Draugr Fiends are aggressive undead that wield dual axes. They have a long combo that can be surprisingly difficult to judge and parry.
Fiends can be a pain if they're grouped up with other enemies. Their attacks tend to be relentless, and they'll skate away from danger if your combo doesn't kill them.
Fortunately, most of their strikes can be blocked, or, if you're feeling confident, parried. A good old fashioned stun might be the best way to deal with a Fiend if you're having trouble, so don't be afraid to get your bare hands out.
