I wish Harry had spent more time looking into the many powerful artefacts he has. I really do. Because after just 10 minutes with the map and the cloak, I made a terrifying discovery. The cloak is one of the deathly hallows, as in, a legendary artefact popularly believed to only be a myth. From my light reading on enchantment and the diagnostic charms that go with it, I also discovered that someone had tampered with it, from what it looks like there are locating and tracing charms applied to the cloak which makes it virtually useless in the face of anyone who can detect simple charms or has an artefact to see magic in it's lower levels, which are mainly used for detecting pranks or even booby traps. Thankfully I'm not an Idiot and dispel them, for a powerful ancient artefact saturated in magic dispelling foreign magic is easy no matter the power of the person that cast the charms simply because by nature such artefacts are resistant to tampering, the magic of the cloak doesn't want those charms embedded in its fabric but it can't dispel them because it has no will, it's simply the natural magic of the cloak fighting the foreign charms that were forcefully attacked to it, so with a simple finite the magic of the cloak combines with the basic cleansing spell and ejects the spells placed upon it and I have a clean Deathly hallow on my hands that I spent most of that year testing to see how far it can go and oh my word does it perform.
