Anybody know how to beat the following:

1.) Umbra
2.) Mannimarco
3.) Umaril the Unfeathered

Take note with OOO, their HP skyrocket to near 850s.

take note that I'm a pacifist (Not doing anything to add my kill count.)

So the only weapons possible are skull of corruption, sanguine rose and command-a-guard. Non are powerful enough, and all of those bosses have a healing spell.

Non-npc can be taken care of Wabbajack+ Sanguine Rose.

If not then I'll just leave their quest unfinished
