I saw before that eternal equips is going to be shown even if your in a eternal league because you can’t edit a eternal equip so it’s easier to spot a cheated item. I can’t remember when it was posted though or if it was just a suggestion. Maybe pets can be shown too because we can base a pet on it’s name and if a set affix was change we could tag the user as a cheater.
For other affixes that isn’t eternal the developers made a item checker to check equips that isn’t possible if equip’s affix is not possible that affix will be turned to an empty slot
You could convert 20 epic chest to legend chest then to 20 legend chest to eternal chest.
Eternal chest is 100% eternal item but still by chance if it’s going to be a chest.
I know the lowest point of getting a gladiator trophy is until your in legend league.
