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.

Both me and my opponent control Personalities which will be destroyed by Fury of the Dark Lord. During my turn, I play Fury of the Dark Lord. As a reaction to my personality´s destruction, I play Assigning Blame on the opponent´s personality. He loses 3 Honor, his personality is dishonored, then destroyed (by Fury of the Dark Lord).
Does this work? Or is his personality already out of play at the time I could play Assigning Blame?
If it works: Will it work if all of my Couriers will be destroyed by Fury of the Dark Lord? (Note the restriction on Assigning Blame)

The latter.
