Yesterday I got Lubrae's Ruin from the Vow of the Disciple raid. But its design differs from other weapons in the same raid.
Weapons from VoD, except for Lubrae's Ruin, all have a pillar formed by a series of square blocks rotating. However, Lubrae's Ruin that we can get doesn't have this kind of design, and it's different from RHULK's one that dropped on the ground when finishing the raid.
