When is an action considered to begin resolving? Is it when it's announced? Or after costs are paid, when the effects begin to resolve? Or is it at any other time?
Action resolution
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.
When is an action considered to begin resolving?
I think I need more context for this one. When effects resolve is usually more important.
That said, the Rules Archive section on Actions may contain useful information.
