I upgraded my Smouldering Core from an ancient to a primal ancient using the cube. After i enchanted and used a gift on it to add a gem slot it is telling me that I can only use one of those items.
You can only equip one crafted primal. Natural dropped primals have no limitations.
That would be whats wrong then. I missed that we could only use one crafted primal.
If you encounter some problems with the armory/wardrobe, you’ll find some informations here
