Could I get a little more clarification on my question. You said that you can't negate the action if you don't target an unbowed tactition. I don't under stand why that's a requirement. I totally understand the INTENT of this card's design but it seems there has been a lot of talk about second effects on cards still going off even if the first effect fails and this card appears to work the same way. I play the interrupt, I bow a tactition if possible and I negate the battle/engage action. If bowing the tactition is not a cost then anyone should be able to play it.

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.

All targeting is mandatory unless imeadiately prefaced with "you may."
Unless you can actually fulfill all mandatory targeting, the action cannot be announced and thus not taken.
This is covered under the second part of the Good Faith Rule, as found in the Reference Rules document.
