JK Rowling is the best.

Voldemort was a real dick in a historical sense I mean he took Slytherin’s locket, Ravenclaw’s diadem and Hufflepuff’s cup and made them horcruxes, leading to them all being destroyed. We know that the diadem had magical properties, and that Gryffindor’s sword was a magically crafted weapon. Honestly I’d have a hard time believing Hufflepuff and Slytherin’s things didn’t have magical properties as well. The locket(before being made into a horcrux) probably only opened to true Slytherins and held their secrets for them. The cup must have supplied resources, or strengthened whatever drink that was put into it to benefit the drinker. Hufflepuff did something rad with that cup. We’ll never know tho exactly what because Voldemort had a huge ass ego and wanted to put his ugly soul in it.
Honestly Voldemort just sucked in every way possible. The only exception would be that he led to the possibility of someone being in possession of all the hallows. I’m also curious though as to how the resurrection stone was affected by being a horcrux. Was the horcrux the stone or the ring itself? Did Voldemort ever use the stone? Is there a chance that he had tracked down the invisibility cloak? Giving him extra motivation to kill the Potters? Honestly JK Rowling shouldn’t have made Pottermore she should have just written a giant ass encyclopedia explaining all these things.
