Draugr Scouts are ranged foes that throw fireballs from a distance. They have both low health and a low stun threshold.
As is the case with any projectile-spewing foe, you should make killing Draugr Scouts a priority. Getting to them can be a hassle if they're fighting alongside other Draugr, but once you're in, they offer little resistance.
Meanwhile, the projectiles themselves can be blocked or parried, and they move quite slowly through the air. A merely annoying enemy at worst.
