A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Regarding this post
Isn't "After the effects resolve" merely a timing trigger for the reaction, and not a restriction that an effect must kill them. Thus a "cost" (e.g. greater sacrifice) of an action would be a valid trigger for Adeiko to use her reaction, though the effects of said action must have resolved before it is legal to announce Adeiko's reaction.
