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 am a bit unsure how to properly word this question so please read it flexibly. Can I use the reaction on Shokushu no Oni with my stronghold being Spider's Lair (does the cost get paid?)?
Reaction: When paying for a Spell attaching to this Personality, lose honor equal to its printed Gold cost: You need not pay its Gold cost.

Yes. For now.
This ruling is tentative and based on some Samurai Edition considerations, which I can't go into detail about. So don't fret about it.
