Rules FAQ

  • The phrase "if able" means that this ability can be initiated even if one or more opponents do not have an eligible attachment to discard. Any opponent who does must still choose and discard one.

  • You can keep initiating this effect as long as you have power on characters and there is at least one attachment that can be discarded from play.

  • An attachment can be saved from this effect. If any attachment is saved, the pre-then aspect of the effect has not successfully resolved in full, so the post-then aspect of the effect does not attempt to resolve either. That means you cannot initiate this effect again in that scenario. (See The word "Then".)

  • If the effect is initiated again, it can be canceled by Outwit or Someone Always Tells, since the triggering condition "when the effects (of something) would initiate" occurs again. Note that the specific wording of this card makes it an exception to the general rule that the post-then aspect of the effect cannot be canceled separately.

  • The pre-then and post-then aspects of the effect share a common reaction window, which opens after the entire effect has resolved. For instance, if a non-loyal attachment is discarded from play, the choice of whether to initiate the effect again happens before the reaction of Edric Dayne (HMW). If multiple non-loyal attachments are discarded by initiating the effect multiple times, Edric can choose among them once the entire When Revealed ability has resolved. (See FAQ.)

One quick comment about the last entry... Since the wording is similar to the original Forced March, there was a dilemma whether to also follow the official ruling about Forced March that was in direct contradiction with FAQ entry 1.8, saying that there is indeed a reaction window between the pre-then and the post-then aspect of the effect. But since the original Forced March is no longer part of the legal card pool, and since that ruling did not elaborate why and in which part it overruled the official FAQ, it was decided to just follow the FAQ instead for Burning the Books and all similar abilities going forward. — Odrl 1245
