Okay, according to Shiro Kitsuki, I pull out 4 non-unique different personalities from my deck and attach away.
What if I can only find 3 or less?
Is the trait a must? Or can you choose to not attach anyone?
SK and attaching personalities
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from the Wayback Machine (its copy), so posts 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.

Hm. As worded, strictly speaking, you must do it. I'm going to kick this to the Rules Junta, though.
You must attach four Personalities.
