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.

Must I still discard a card if I use the Stronghold action of Temple of Purity on Bofana? It was my understanding that even though the trait doesn't specifically target the Stronghold, that the Stronghold is still immune such things. But in light of this ruling, I'm no longer sure.

Only Personalities and Followers may perform actions.
Therefore, assuming you're referring to Daigotsu Bofana, any action from a Stronghold will not be performed by a card with force equal to or higher than his base force, and the player who took the action will need to discard a card if it is the first such action of a phase.
