Obviously the scariest mob is going to be the heavy hitter in whatever the latest biome is. I think the most dangerous mob relative to the gear + food one level below the biome they live in is indeed the 2* draugr archer. They are ranged and can easily one shot you at that level.

As mentioned above, the 2 star mages may actually be even scarier than this one even relative to the biome, but since they aren't hostile I don't include them.
