What does it mean if an item is glitched?

more defence

u take an eth armor ( or item using armor as ex.) cube it with tal thul ptopaz ( other items require different recipies) transmute and it add 50% more def and random socks 1-4( depending on armor and max socks or the armor ofc

eth armors can be socketed using cube recipe, and it will also get a defense bonus. if you get lucky and roll the right number of sockets along with the bump in defense, you got a winner
