Kimandatsu (Thorborg Silverskorr) escaped the final battle of Night of Frozen Shadows.
This battle took almost 3 hours of real time, but in the end Kimandatsu was forced to flee because of a 1st-level spell:
The wizard cast Grease spells on each of her weapons (first Oathtaker, then her bow). With her low REF, she failed the initial REF saves thus she would have to make additional saves for the next few minutes just to pick her weapons back up...
(The grease spell ignores her SR)
So I had her go invisible and into gaseous form and escape.
Question: how/when would she mount a revenge attack (especially after realizing her Rimerunners Guild cover has been blown and all her Frozen Shadow allies have been killed)?
I believe it is suggested in the book that she would gather some reinforcements (call in nearby ninja from assignments, or get fresh troops from Minkai) and harass the PC's during the trek across the crown of the world in the next book.
