Item altering idea

what if they added a very hard boss in game , once you kill him your able to add a 2nd aspect to an item with a chance to delete the item, or add a rare orb in game that allows a chance to add 2nd aspect to an item which slight chance to lose or ruin that item. Or maybe add a rare ointment you can get from a new rare treasure goblin that allows you to do this.
Also would like to see some Seasonal mechanics with new types of items/loot along with it.
What do you guys think

So unnerf Uber Lilith and make her the farm boss is what you’re saying

sure same concept. I wouldnt mind it
