Can you use Hand of the Jade Dragon's reaction to negate the attached personalities death if doomed undertaking gives the personality a zero chi or lower?
Hand of the Jade Dragon:
After an action resolves: Negate this personalities destruction from the actions effects.
Doomed Undertaking:
Terrain Battle: Non shadowlands personalities have -2f/-1c
I dont remember where I found this at, but it was ruled that:
A chi penalty death results from the last action that gave a chi penalty, or from the rulebook if no such action took place.
