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 you bow a shugenja for Shiba Iaimiko's ability, do you get both +1 Force and cavalry?
When you bow a shugenja for Shiba Iaimiko's ability, do you get both +1 Force and Conqueror?
Or just +1 force or the trait(s)?
Iaimiko reads;
Open: Bow your target unbowed Shugenja or Ikoma Aimi to give Iaimiko +1F, Cavalry, or Conqueror. You may use this action three times per turn.
Sorry about the repeat, I was unclear how to word it.

Only one of the three, your choice, but no more than one. The conjunction "or" is only written once because we still write the cards in proper english, and grammar says multiple disjunctives need just one conjunction before the last of the alternatives.
