SeanOfTheShred There is a Dungeon called Temporal Sanctum. After defeating the Dungeon Boss you are allowed to transfer mods from an exalted item from the same item type to an Unique.
Let's say you have a 2LP Jelkhors Dagger, then you can craft an exalted dagger for it with desired mods.
The dungeon craft at the end will randomly pick 2 mods of the exalted item and transfer it onto the unique.
Best case scenario would be an exalted dagger with Melee Attack Speed, Melee Lightning Dmg, Chill Chance, Armour Shred. All 4 will benefit to the build.
