Welcome to the Official Redemption® Message Board!
ITB only applies to the battle you are in. It would d/c sword of the Lord, but not much else.
The card says to interrupt and discard all good Enhancements in play. That applies to every single one in the Field of Play, on either side of the table, and in (unprotected) Fortresses, and placed on other cards. EVERYthing.The default rule for the current battle applies to the term "in battle".As a side note, ITB was mentioned briefly in this thread but Devourer does not have the ability "interrupt the battle". It specifically targets all good Enhancements.
