Could one perhaps require from the Room of Requirements an object which is powerful enough to destroy a Horcrux?

Let's say you could even be specific, for example: 'I need a Basilisk Fang'.

I'm not saying why didn't this happen because that would be silly, but is this possible?


More than just a Basilisk Fang; what about the Sword of Gryffindor (after is is imbued with the Basilisk venom)? or any other known destroyers of a Horcrux?

    I suppose that the Room might do some sort of sanitation of requests (e.g. “I want a terrible weapon to destroy the entire castle” would be declined) to ensure your safety, and the safety of the rest of the castle. Since most anti-Horcrux tools are deadly weapons (Basilisk fangs, venom-tinged swords, FiendFyre), I wonder if this might get turned down. Just a thought. – alexwlchan Mar 12 '14 at 8:56

    Further, can the room actually be used just to produce stuff? If it could, we'd perhaps have: "I need a five-foot long essay for Professor Snape on Amortentia." Maybe the room can be used only to, uh, transform itself into a room which would satisfy the needs of the person. Like the DA asked for a room to practice DADA, so that's what they got. There is a mention of Dobby finding antidotes and a bed, but he may have asked for a nursing room for a wounded elf. Just a thought. :D – The Dragon Rider who Lived Apr 17 '14 at 8:51


The room seems to operate under Gamp's Law of Elemental Transfiguration.

So, if Basilisk fangs are part of one of the Five Exceptions to it (we only really know one exception from canon - food), they wouldn't be possible to obtain; otherwise they should be possible.

    Basilisk fangs are body parts of a living being and living beings can generally be used as food. Maybe this argument support the applicability of Gamp's Law of Elemental Transfiguration. – Philipp Mar 12 '14 at 15:35
  • @Philipp Mar: What if you simply asked for "a vial of Basilisk venom"? It might be able to get around "no body parts/food(-like) items" exception. We know that Filch occasionally found some cleaning products when he needed them (OotP,Ch18) and that Dobby found some "butterbeer antidotes" (same chapter) so certain (non-edible) substances might be feasible. – Fen1ks Mar 31 '14 at 13:31
  • @DVK - Basilisk fangs are just 1 example. It is not the only thing that can destroy a horcrux. The room can generate inanimate objects. The sword of Godric Gryffindor was an inanimate object. I think the question also covers such objects. – Stark07 Apr 17 '14 at 4:49
  • @Philipp can you use a basilisk fang as food? I don't think so... therefore, if Basilisk fangs are part of one of the Five Exceptions, they can only be part of one of the other four exceptions. – A. Darwin Feb 28 '16 at 10:17

I'd imagine it falls under the Law of Elemental Transfiguration. The Room of Requirement is subject to this law (cannot summon food) and there are four other categories of non-transfigurable/summonable items not explicitly mentioned in the books, which may include Basilisk fangs in some way. I'd imagine "body parts" is a reasonable candidate for one of the other categories.

  • "Which may include" and "I'd imagine" are generally not found in a good answer. Those phrases are indicative of opinion and conjecture. (Not downvoting or voting to close, just a comment.) – Meat Trademark Mar 12 '14 at 6:28

    I guess this would be a tricky question to answer without some amount of conjecture. – Möoz Mar 12 '14 at 20:24
