This profile performs best using a melee class or hunter, as the ghosts have very low armor.
But any other is of course also fine.
Your char should be able to handle 2 mobs simultaneously though.
The ghosts also have less life but they hit hard.
They drop greens,rune cloth and enchant icy chill, so do not forget to deactivate skinning.
I used it from 54 to 60.
Ghost path begins next to Everlook.
