As some of us may know when you try to equip for example (level 60 blindfold) when you are level 50 it wont let you equip the item in your vanity slot. You should be able to equip high level items for vanity regardless of your actual player’s level.
Accessories include Sunken Helmets, Wizard Hats, Amulets, etc. They need levels or else you can wear a Singularity Power Amulet at level 1, they would also be un-upgradable without a revamp to the system
id say this would be good for jen’s hat could be obtained at your level (like your example, a blindfold can obtained at level 50 so therefore a level 60 one should be allowed to vanity only) but i wouldn’t say the same for items you haven’t even unlocked yet. would be kinda weird for a level 10 to be rocking a singularity amulet.
