Sabway is way overloaded with defense if you're running a SY warrior and/or 2 monks. I cleared all 4 back to back with the following:
Human W/A: 14 Swordsmanship, 13 Strength
[skill]dragon slash[/skill]
[skill]flail[/skill][skill]enraging charge[/skill][skill]"for great justice!"[/skill][skill]swap[/skill]

Take along Cynn, Lina, Mhenlo and Zho. SV/AV removes the need for Frozen soil because they don't have enough energy to heal, let alone res (take the cleaver's out first). SV/SoS on the death nec and swap on the human assumes you're using the "cheap" method of taking out Duncan (not entirely a problem - you can just flag your nec in place while you go off and watch some tv or something. Lina/Mhenlo will happily keep her alive and she'll slowly kill Duncy over 10-15minutes).
