Learn how to unlock Sorcerer Enchantment Slots in Diablo IV by completing the 'Legacy of the Magi' quest, finding the Forgotten Codex, and understanding how enchantments work.
To unlock Enchantment Slots, you must reach level 15. This will trigger the quest Sorcerer: Legacy of the Magi. Your first objective is to travel to the southwestern Desolate Highlands in Fracture Peaks to find Mordarin. He needs the book called the “Forgotten Codex,” which is guarded by demons in a nearby dungeon.
Head east to find The Lost Archives dungeon. You don't need to clear the entire dungeon, but you must complete the first objective, “Slay the Demonic Vanguard.” After that, look for a “Dust-Covered Chest” to find the Forgotten Codex. You can ignore the second objective, “Return the Mechanical Box to the Pedestal.”
Once you have the Forgotten Codex, return to Mordarin. Follow him into his shack and assist him with a ritual by lighting braziers. Demons will appear; defeat them. Mordarin will then give you the Forgotten Codex.
The Forgotten Codex unlocks your Enchantment Slots. To use them, go to your skill tree and access the skill equipment menu. There are two slots labeled “Enchantments” below the skill icons. You can equip any skill you know into these slots for a passive bonus. One slot unlocks at level 15, and the second at level 30.
