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.
The lotus edition rulebook claims that face down personalities with the ninjitsu trait can attach items, spells, and followers regardless of normal restrictions. However, just because they have spells attached doesn't mean they can use them... right?
Correct.
