If you could use a level 35 epic amulet for example and trade it in to a vendor for another random epic amulet (Iron bits cost aswel ofc) from level 32 - 37 or something x) . I feel this would help players in the early game and unlucky ones later game aswell ^^
EDIT : I would like to add that maybe there could be a 20% chance it turns into a random yellow amulet which cant be gambled. I forgot to mention that the lowest rarity you could use it with would be Epic+. I know its like Diablo’s Kadala but its a much better format then Kadala, it adds an additional Iron Bits sink.
