If a personality can no longer perform actions due to The Direct Approach can he seppuku?
The Direct Approach and seppuku
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.
If a personality can no longer perform actions due to The Direct Approach can he seppuku?
If the rulebook reaction is used, yes.
