I have noticed at this point it is currently impossible to enchant boots, bracers and jewellery(Rings, Earrings and Necklace). And I have just crafted the Purple Rarity Oathbreaker Greatsword and that weapon is not enchantable either? is that a bug or intended?
Have not yet been able to craft other purple rarity armour or weapons to check if they can be enchanted.
Or is there another location that I haven't found yet that has higher tier enchanting
