Infusion
Infusion is the process of converting rare equipment into epic equipment.
Weapons - Requires completion of the quest "The Lost and Found" in Episode 3: "Mine of Mantuban" - Requires 3 rare (purple) weapons, one from each faction (Guardian, Cryoknight, Hammermage). - Go to an Obelisk, and select the option to infuse. - All 3 items will be consumed to convert the centermost item to Epic rarity. - The level of the created item will be an average of the 3 rares that were used (?).
Armour - No idea if it will be added, but it seems reasonable to expect that it will.
