The latest update to Diablo 4, titled Lord of Hatred, introduces the Horadric Cube as a significant crafting tool, enhancing gameplay mechanics and altering the trading ecosystem. Blue-rarity magic items, previously considered salvage, can now be valuable for crafting, with max-level blue items selling for tens of billions of gold and rare items with desirable affixes approaching 100 billion. The crafting process allows players to customize items to fit their builds, increasing the value of lower-rarity items and encouraging exploration of trading opportunities. The satisfaction from crafting is noted to surpass that of simply purchasing items.
