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.
I'm pretty sure I'm correct, but in regards to viewtopic.php?f=59&t=90580
If an ability that reads:
Tactical Battle: blah blah blah
is copied by (or on to) a personality without the tactician keyword, then that personality cannot perform the action correct?
