I thought I read somewhere that when you win a duplicate item, you can trade it for essence. Anyone know how this works? I have a duplicate protective tablet that I'd like to get rid of... it would be nice to get something in return. Thanks for the help!
Sorry, your slightly mistaken. When you win a hero or a skin, that you already own, that will automatically trade for essence. Tablets, inscriptions, consumables are not included in the sanctum. Its purely heroes and skins. Welcome to the forums!
Should also note that you only win essence in the Deluxe Lottery, the 65-emblem lottery transfer fragments for Gambler's Greeds.
