I came here on an unrelated question, but answered my own problem through the powers of the search tool. I did some across this thread, however, which is still under discussion. May I ask why that is? From the EE Rulebook's Chi Death Rule: "This destruction for having zero Chi may only be negated or prevented by effects that specifically negate or prevent destruction for having zero Chi."
Neither Megumi's Guidance nor Wide Valley specifically negate the destruction for having zero Chi. Gift Armor, of course, does (because it negates Chi penalties in the first place), although in the example where the Armor is removed, the Personality still dies from Chi death (and from the rulebook rather than an action, so neither other negation would have applied anyway, I don't think).
